BIOS Setup Utility
The AMI BIOS Setup utility program is used to configure the main components
of the computer.
The computer ships from the factory with the correct system parameters for the
configuration. Unless optional hardware is added, it’s not necessary to run the
BIOS Setup utility to operate the system. However, the Setup utility should be
run to set features that customize the system, such as security features.
System configuration information is stored in a nonvolatile memory device. The
device retains its data when system power is turned off. Nonvolatile memory is
stored in a complementary metal-oxide semiconductor (CMOS) memory chip
backed up by a battery on the system board. The battery supplies continuous
power to CMOS memory and maintains configuration information when system
power is off (see “Battery Replacement” in Section 3).
NEC CSD recommends that the current BIOS Setup parameters be printed out
or written down and the information stored in a safe place. This lets you restore
the system to the current parameters if replacing the battery.
How to Start BIOS Setup
Follow these steps to start the BIOS Setup utility.
1. Turn on or reboot the system.
2. Press F2 as soon as you see the following message at the bottom of the NEC
startup screen.
Press F2 to enter BIOS Setup
You have about five seconds to press F2 before the system boot continues.

FLASH Utility
The system BIOS resides on a ROM chip in the system and is updated using the
following procedure. Before starting the BIOS update, NEC recommends that
you first contact NEC CSD for assistance (see Section 8 for contacts).
Update the Flash ROM with a BIOS flash diskette. You can get the diskette
from NEC CSD or download the BIOS from the NEC CSD website or Bulletin
Board System (BBS). See Section 8 for download, website, and bulletin board
system information.
Update the BIOS from the BIOS flash diskette as follows.
1. Write down the BIOS Setup parameters currently set on your system, then
turn off the system.
2. Put the flash diskette in drive A and turn on the system.
3. At the flash upgrade menu, type Y (without parenthesis) when prompted to
save the existing BIOS.
When asked for a file name for the existing BIOS, choose a name easily
recognized and with no more than eight characters. An extension is not
required but, if desired, you can use .rom (without parenthesis).
Press Enter to save the existing BIOS file.
4. At the prompt asking for a file name for the BIOS update:
Use the form biosname.rom where biosname represents the BIOS
filename of the BIOS update on the diskette.

NEC OS Restore CD
The following procedures describe how to use the NEC OS Restore CD that
ships with the system.
Read the following subsections in their entirety before using the NEC OS
Restore CD to restore the Windows operating system or factory-installed drivers
on the system.
Introducing OS Restore Options
The NEC OS Restore CD contains the Windows 95, Windows 98, or Windows
NT operating system and device drivers for the hardware that was factory-
installed in the system. Use this CD to restore the system to its working state if a
problem occurs that causes data loss or corruption.
After restoring the operating system, use the NEC Application and Driver CD to
install applications, optional drivers, and online documents.
Note: Use the NEC Application and Driver CD to install or
restore applications, optional drivers, and online documents (see
“NEC Application and Driver CD” later in this section).
Choosing a Restore Program
The OS Restore program allows you to reinstall the Windows 95, Windows 98,
or Windows NT operating system. Restore can be done in the following ways:
Auto, which reformats and repartitions the hard drive before restoring the
Windows OS and factory-shipped drivers (see “Auto Rebuild and
Restore”)
Custom, which reformats the hard drive with the option to repartition
before restoring the Windows OS and factory-shipped drivers (see
“Custom Rebuild and Restore”)
Fix OS for Windows 95 and Windows 98 systems, which reinstalls the
Windows OS while leaving data files intact. This restores the system to
where you can back up data files. This option is intended as a precursor to
a full format and restore (see “Fixing the Operating System”).
System Configuration 2-19
Download from Www.Somanuals.com. All Manuals Search And Download.
The operating system and factory-shipped drivers are always restored regardless
of which program was chosen.

Intel Processor Serial Number Control Utility
The Intel Processor Serial Number Control utility is a Windows program that
enables or disables the reading of the Pentium III processor serial number by
software. This function lets you control which software programs or websites
have permission to read the processor serial number. When installed, the utility
runs automatically each time the system powers on.
Note: The Intel Processor Serial Number Control Utility
is for use with systems shipping with the Intel Pentium III
processor. Installing this utility on a system which does not
contain a Pentium III processor generates an error message.
This utility places an icon in the Windows system tray. The icon provides a
visual status of the processor serial number. You have the option of hiding the
system tray icon. You can disable the processor serial number at any time.
However, enabling the serial number requires restarting the system.
The following information describes:
system requirements
installation procedures
processor serial number features
FAQs
errata
technical support.
System Requirements
The Intel Processor Serial Number Control utility requires:
Pentium III processor-based system
Windows 95, Windows 98, or Windows NT® 4.0 (or later)
2 megabytes of hard drive space.
Installation
The Intel Processor Serial Number Control Utility (version 1.0) comes on the
NEC Application and Driver CD. See the user’s guide for information about
using the NEC Application and Driver CD. Run setup.exe from the directory
where you unzip the file.

Processor Serial Number
The Intel processor serial number, a new feature of the Pentium III processor, is
an identifier for the processor. The processor serial number is designed to be
unique, and when used in conjunction with other identification methods, can be
used to identify the system or user. This number can be used in a wide variety of
applications which benefit from stronger forms of system and user
identification.
The processor serial number is analogous to a conventional serial number, with
these important differences:
A software application can read the processor serial number.
You can disable the reading of the serial number via utility programs
such as this one, or via the BIOS, depending on the system configuration.
For additional information about the Pentium III processor and the processor
serial number, please visit www.intel.com/pentiumiii.
FAQs
What are the benefits of the processor serial number?
You can use the processor serial number in applications which benefit from
stronger forms of system and user identification.
Why would I want to turn off my processor serial number?
Intel believes the processor serial number can provide compelling benefits to
users. They are developing features in conjunction with the processor serial
number to allow responsible service providers to provide services which
maintain your privacy. However, if you are concerned that a given
application/service using your processor number might impact your privacy, you
can turn off the processor serial number using the utility.
What is the default state of the processor serial number?
The default state of the processor serial number is on, until the Processor Serial
Number Control utility is installed. Once the Processor Serial Number Control
utility is installed, it turns the processor serial number off by default. You can
use the utility to turn on the processor serial number.
Can a website read my serial number without my knowledge?
No, generally not. Websites cannot read serial numbers unless you allow them
to download a program which can read the processor serial number. Almost all
browsers are configured to warn users whenever they download executable
software. Unless you disable the warning in the browser, you should receive a
notification.

Does Intel track serial numbers?
Generally not, other than related to the manufacturing process. Intel does not, in
the absences of advance and express consent of a user, collect serial number
data which is otherwise identified with a user.
Which programs and/or websites currently use the processor serial
number?
You can find a complete list of programs which can take advantage of the
processor serial number and other new capabilities of the Pentium III processor
at http://www.intel.com/pentiumiii/utility.htm.
How can I tell if my processor serial number is turned on?
The vast majority of Pentium III processor-based systems ship with the
processor serial number enabled. The control utility allows you to check the
status by:
Viewing the icon itself. The disabled icon shows a red circle with a
white “x.”
Clicking the task tray icon and selecting the “Status” menu item. Or you
can select the menu from the tool tip shown when you position the mouse
over the task tray icon.

Processor and Secondary Cache
The system uses an Intel Celeron, Pentium II, or Pentium III processor with an
internal clock speed of 300 MHz, 333 MHz, 350 MHz, 366 MHz, 400 MHz,
433 MHz, 450 MHz, or 500 MHz (depending on type of processor and model).
The processor is an advanced pipelined 32-bit addressing, 64-bit data processor
designed to optimize multitasking operating systems. The 64-bit registers and
data paths support 64-bit addresses and data types.
To use the processor’s power, the system features an optimized 64-bit memory
interface and 512 KB (128 KB for Celeron) of secondary write-back cache on
the processor.
The processor is compatible with 8-, 16-, and 32-bit software written for the
Intel386™, Intel486™, Pentium, and Pentium Pro processors. The processor is
mounted in S.E.C. cartridge with an attaching heatsink that installs as a unit in
Slot 1 on the system board.
System BIOS
The ISA- and PCI-compatible BIOS is contained in a flash memory device on
the system board. The BIOS provides the Power-On Self-Test (POST), the
system Setup program, a PCI and IDE auto-configuration utility, and BIOS
recovery code.
The system BIOS is always shadowed. Shadowing allows any BIOS routine to
be executed from fast 32-bit DRAM on the system board, instead of from the
slower 8-bit flash device.
The Flash ROM allows fast, economical BIOS upgrades. The Flash ROM is a
reprogrammable EPROM containing both the system and video BIOS. Using
the Flash ROM to change the ROM BIOS provides the following advantages:
the BIOS upgrade is performed quickly and easily
the expense of replacing ROM BIOS chips is eliminated, so system
maintenance costs are reduced
there is less chance of inadvertently damaging the system board than
when physically replacing ROMs
new technology can be incorporated while maintaining corporate
standards
network administrators can exercise company-wide control of BIOS
revisions.
The BIOS programs execute the Power-On Self-Test, initialize processor
controllers, and interact with the display, diskette drive, hard drives,
communication devices, and peripherals. The system BIOS also contains the
Setup utility. The POST copies the ROM BIOS into RAM (shadowing) for
maximum performance.
4-12 System Board
Download from Www.Somanuals.com. All Manuals Search And Download.
The Flash ROM allows the system and video BIOS to be upgraded with the
BIOS Update utility, without having to physically remove the ROM (see
Section 2 for further information on the BIOS Update utility). The Flash ROM
supports the reprogramming of the system BIOS and the video BIOS.
System Memory
The system comes with between 32 MB and 256 MB of SDRAM installed in
DIMM sockets on the system board.
The memory configuration consists of two sockets. The DIMM sockets accept
168-pin, 64-bit (non-ECC) 16-, 32-, 64-, and 128-MB DIMMs. See “DIMM
Sockets” for a list of supported DIMMs.
Plug and Play
The system comes with a Plug and Play BIOS in support of Plug and Play
technology. Plug and Play simplifies setup procedures for installing Plug and
Play expansion boards. With Plug and Play, adding a Plug and Play expansion
board is done by turning off the system, installing the board, and turning on the
system. There are no jumpers to set and no system resource conflicts to resolve.
Plug and Play automatically configures the board. (Some Plug and Play devices
may need to be jumpered if used in a system running the Windows NT
operating system.)
ISA Bus
The system board uses the ISA bus for transferring data between the processor
and some I/O peripherals and expansion boards. The ISA bus supports 16-bit
data transfers and typically operates at 8 MHz.
PCI Local Bus
The 32-bit PCI local bus is the primary I/O bus for the system. The PCI bus is a
highly integrated I/O interface that offers the highest performance local bus
available for the Celeron or Pentium processor. The bus supports burst modes
that send large amounts of data across the bus, allowing fast displays of high-
resolution images.
The PCI local bus is a high-performance bus that provides a processor-
independent data path between the CPU and high-speed peripherals. The PCI
bus is a robust interconnect mechanism designed specifically to accommodate
multiple high performance peripherals for graphics and full motion video.
The PCI local bus supports memory transfer rates of over 100 MB per second
for reads and over 120 MB per second for writes, depending on processor
configuration.
System Board 4-13
Download from Www.Somanuals.com. All Manuals Search And Download.
PCI/IDE Ports
The system board supports two high-performance PCI/IDE ports: a primary port
and a secondary port on the system board. Each port supports up to two devices
for a total of four IDE devices. The primary PCI/IDE port has an enhanced IDE
interface that supports PIO Mode 4 devices with 16 MB per second 32-bit wide
data transfers on the high-performance PCI local bus. Each port supports Ultra
DMA/33.
The installed hard drive is connected to the primary PCI/IDE connector with a
three-connector cable. If a CD-ROM drive is included in the system, it is
connected to the secondary PCI/IDE port with a three-connector cable. A second
device can be added to the primary PCI/IDE port.
Parallel Interface
The system has a 25-pin bidirectional parallel port on the system board. Port
specifications conform to the IBM-PC standards. The port supports Enhanced
Capabilities Port (ECP) and Enhanced Parallel Port (EPP) modes for devices
that require ECP or EPP protocols. The protocols allow high-speed bi-
directional transfer over a parallel port and increase parallel port functionality
by supporting more devices.
The BIOS has automatic ISA printer port sensing that works with most devices.
If the BIOS detects an ISA printer port mapped to the same address, the built-in
printer port is disabled. (Verify in the BIOS Setup that printer ports mapped to
the same address are enabled or disabled appropriately.) The BIOS also sets the
first parallel interface port it finds as LPT1 and the second port it finds as LPT2.
The interrupt is set at IRQ7 via the BIOS Setup utility. Software-selectable base
addresses are 228h, 378h, and 278h.
Sets of I/O addresses for the parallel port are given in the following table (see
Section 2, “System Configuration,” for interrupt levels). This is a list of all
possible configurations; the parallel port uses only one set.

Serial Interface
The system has two 16C550 UART compatible serial ports (COM1 and COM2)
integrated on the I/O controller. The serial ports support the standard RS-232C
interface. The buffered high-speed serial ports support transfer rates up to
115.2 KB. These ports allow the installation of high-speed serial devices for
faster data transfer rates.
Sets of I/O addresses for the two channels are given in the following table (see
Section 2, “System Configuration,” for interrupt levels). Soft-selectable base
addresses are 3F8h, 2F8h, 3E8h, and 2E8h.

through the BIOS Setup utility. See Section 9, “Specifications,” for the serial
interface specifications.
Serial interface signals are output through the system board’s 9-pin,
D-subconnectors. The connectors are located at the back of the system unit.
USB Interface
The Universal Serial Bus (USB) ports allow new Plug and Play serial devices to
be added without having to open the system. One USB device may be plugged
into each USB port for direct system connection. With a hub and the proper
cabling, up to 127 USB devices per port can be addressed by the system. The
USB determines system resources for each peripheral and assigns them without
user intervention. Boot support for a USB keyboard is present so the system can
be booted with a USB keyboard instead of a standard keyboard.
Graphics Capabilities
The system supports AGP boards and PCI graphics boards. A PCI graphics
board installs in one of the computer’s PCI expansion slots. An AGP board
installs in the system board’s AGP slot.

Download from Www.Somanuals.com. All Manuals Search And Download.
This section contains general information for cleaning and checking the system,
keyboard, and monitor.
The system unit, keyboard, and monitor require cleaning and checking at least
once a year, and more often if operating in a dusty environment. No other
scheduled maintenance is required.
!
WARNING
Unplug all power cords before performing any maintenance.
Voltage is present inside the system and monitor even after
the power is off. All voltage is removed only when the power
cord is unplugged.
System Cleaning
Use the following procedure for cleaning the system.
1.
2.
Power off the system and unplug all power cables.
Wipe the outside of the system, keyboard, mouse, and monitor with a soft,
clean cloth. Remove stains with a mild detergent. Do not use solvents or
strong, abrasive cleaners on any part of the system.
3.
4.
Clean the monitor screen with a commercial monitor screen cleaning kit. As
an alternative, use a glass cleaner, then wipe with a clean lint-free cloth.
Local distributors and dealers may sell diskette drive head cleaning kits.
These kits contain special diskettes and cleaning solution. Do not use the
abrasive head cleaning kits (kits without cleaning solution).
Insert the diskette immediately after powering on the system, before disk
bootup. Allow the diskette drive heads to clean for about 30 seconds.
Keyboard Cleaning
As necessary, inspect and clean the inside of the keyboard as follows.
1.
Turn the keyboard over and remove the screws holding the keyboard
enclosure together.
!
CAUTION
The keyboard and cable together are considered a whole-
unit, field-replaceable assembly. Therefore, disassembly of
the keyboard is necessary only when cleaning the inside.
2.
Separate the two halves of the enclosure.
6-2 Preventive Maintenance
Download from Www.Somanuals.com. All Manuals Search And Download.
3. Clean the enclosure and keys with a damp cloth. A small, soft-bristle brush
may be used to clean between the keys.
Do not wet or dampen the keyboard’s printed circuit board. If the board gets
wet, thoroughly dry it before reattaching the keyboard to the system unit.
Mouse Cleaning
The mouse has a self-cleaning mechanism that prevents a buildup of dust or lint
around the mouse ball and tracking mechanism under normal conditions.
Periodically, however, the mouse ball must be cleaned. Use the following
procedure to clean the mouse.
1. Unplug the mouse from the system.
2. Turn the mouse upside down and locate the ball cover.
3. Turn the ball cover counterclockwise and remove the cover.
Removing the Mouse Ball Cover

Troubleshooting
Checklist
Diagnostics
Download from Www.Somanuals.com. All Manuals Search And Download.
This section provides information to help isolate and repair system malfunctions
at the field level. The system has a built-in program that automatically checks its
components when the system is powered on. If there is a problem, the system
displays an error message. If this happens, follow any instructions on the screen.

information in this section to help determine and correct the problem. For the
more common problems, refer to “Checklist” for assistance. If the information
in the checklist does not help, refer to “Diagnostics ” for more detailed problem
solving.
If disassembly is required, see Section 3, “Disassembly and Reassembly.”
Jumper settings are given in Section 2, “System Configuration” and in
Section 4, “System Board.”
Checklist
Check the following list for a match to the system problem and the possible
cause and solution.
System Problems
No power and power lamp not lit.
Check that all power switches are on.
Check that the power cable is plugged into the system power socket and
that the other end is plugged into a live, properly grounded AC power
outlet or surge protector.
Check the outlet or surge protector by plugging in a lamp.
Non-System Disk error message displays when the system is started.
A diskette is in the diskette drive, and the diskette drive is set before the
hard drive in boot order. Remove the diskette from drive A and restart the
system.
Operating system not found error message displays when the system
is started.
If a CD is left in the CD-ROM drive, the system may not be able to boot.
Try removing the CD and rebooting.
The hard drive might need more time to spin up before the system boots.
Change the “Hard Disk Pre-Delay” to a higher setting from the BIOS
Setup utility.
System does not boot and error message displayed on screen.
Run the Setup utility (see Section 2, “System Configuration”). Check that
the parameters are set correctly, particularly if you just installed an
option.
7-2 Troubleshooting

System emits continuous beeps.
Turn the system off, wait at least five seconds, and turn the system on. If
the beeps continue, call the NEC CSD Technical Support Center.
System does not maintain date, time, system configuration
information.
Change the battery (see “Battery Replacement” in Section 3,
“Disassembly and Reassembly”).
System does not boot from hard drive.
The system usually tries to start from the diskette drive before it starts
from the hard drive. Remove the diskette from the diskette drive.
Run the Setup utility (see Section 2, “System Configuration”) and set the
initial Boot parameter to Hard Drive instead of Removable Device.
System does not boot immediately after hard drive spins up.
The “Hard Disk Pre-Delay” in the BIOS Setup utility can be changed to a
lower setting. (If a message “operating system not found” appears after
changing the setting, the delay is set too low. Set the hard disk pre-delay
slightly higher.)
System performance appears sluggish.
Check that the system is set for optimal operation. See the operating
system documentation.
Check the memory requirements of the software applications. If required,
install additional DIMM memory.
If optional DIMM memory was added, check that it is correctly installed.
System password forgotten.
Clear the password and reset it. See “Clearing the CMOS and Password”
in Section 4, “System Board.”
Microsoft Windows does not recognize the Pentium III processor
Windows incorrectly identifies the Pentium III processor as a Pentium II
or Pentium Pro on the General tab of the Windows System Properties
sheet. This does not effect in any way the performance of the Pentium III
processor. The system BIOS correctly detects the Pentium III processor at
startup. A patch can be obtained to fix the identification in the General
tab. Check for the patch at Microsoft’s website (www.microsoft.com) or
the NEC CSD website (www.nec-computers.com).

the Help menu, and select Product Update. This procedure takes you to the
Microsoft Internet Explorer 4.01 website where you can install these
components.
Identifying the Pentium III Processor
NEC computer systems with the Intel® Pentium® III processor come equipped
with the most advanced Intel Pentium processor available.
Because the new Pentium III processor was introduced after the release of
Microsoft® Windows® 98, Windows 95, and Windows NT® operating systems,
these operating systems are not able to correctly identify the processor. These
operating systems might identify the Pentium III processor as a Pentium II or
Pentium Pro processor.
Windows identifies the processor on the General tab of the Windows System
Properties sheet. You can get to System Properties in either of the following
ways:
Right click the My Computer icon on the Windows desktop and select
Properties from the drop-down menu.
Select Settings from the Windows Start menu, click Control Panel,
double click the System icon.
The Windows System Properties processor identification does not effect in any
way the performance of the Pentium III processor. At bootup, the system BIOS
detects the Pentium III processor.
You can obtain a patch to fix the Windows processor identification once
Microsoft releases the patch. Check for the patch on the Microsoft website
(www.microsoft.com) or NEC CSD website (www.nec-computers.com).
SCSI Drive Limitations
The following procedures and operating limitations apply to systems whose only
hard drive is a SCSI device.
Booting from a CD
In systems with only a SCSI hard drive, it is not possible to boot from an IDE
CD-ROM drive.

Using the NEC OS Restore CD with a SCSI Drive
If a situation arises in which a full operating system restore must be performed
using the NEC OS Restore CD, first boot the system from the bootable diskette.
(This might be necessary, for example, if the system does not boot from the hard
drive.) The bootable diskette comes with all systems that have a SCSI hard
drive. After the system boots, proceed with the NEC OS Restore procedure.
LS-120 SuperDisk Copy Utility
Using the LS-120 SuperDisk™ Copy utility on 1.44-MB or 120-MB media
intermittently causes system lockups and diskette eject failures. This condition
only occurs when you use the SuperDisk Copy utility supplied with the
SuperDisk Tools diskette shipped with the system.
To safely copy a 1.44-MB diskette, NEC CSD recommends using the standard
Microsoft® Disk Copy program supplied with the Microsoft Windows®
operating system. You can find the Microsoft Disk Copy program by double
clicking My Computer and right clicking the LS-120 icon. The context menu
displays Copy Disk as one of the available items. Using this Copy Disk program
allows the LS-120 SuperDisk drive to copy 1.44-MB diskettes without system
lockups and allows the drive to eject the 1.44-MB diskette. However, this utility
does not copy 120-MB media.
If you need to duplicate 120-MB media, you must use the SuperDisk Copy
utility. To avoid data loss, make sure you save all data and close all applications
before you attempt to copy 120-MB diskettes with the SuperDisk Copy utility.
To recover from a diskette eject failure or a system lockup after completing the
SuperDisk Copy, restart the system by pressing the power button to turn off the
system. Then press the power button again to turn on system power.
LS-120 SuperDisk Copy issues are currently under investigation and will be
fixed in the next version of the SuperDisk Utilities. Please check the NEC CSD
website below for updates.

NEC OS Restore CD
The following sections provide information about the “Fix OS” Restore option
on the NEC OS Restore CD. Please use this information in place of the Fix OS
information in the Chapter 3 “NEC OS Restore” sections of your
PowerMate VT 300i Series User’s Guide.
Using the Fix OS Restore Option
“Fix OS” is a Restore option on the NEC OS Restore CD for Windows 95 and
Windows 98 systems. The Fix OS restore option reinstalls the Windows
operating system while leaving data files intact. It allows you to restore your
system to the point where you can back up your data files. This option is
intended as a precursor to a full format and restore. See the next section, “Fixing
the Operating System,” to perform this restore procedure.
Fixing the Operating System
Use the following procedure to restore the operating system to a state for
retrieving and backing up data without repartitioning or reformatting the hard
drive. Once all data is backed up, perform another NEC OS Restore using the
Auto or Custom mode.
!
CAUTION
The Auto and Custom OS Restore programs delete all the
data on your hard drive. If possible, back up your data
before performing an OS Restore with these options.
1.
Launch the NEC OS Restore CD and follow the prompts to get to the
Restore Mode screen (see “Launching the OS Restore CD” in Chapter 3 of
the PowerMate VT 300i Series User’s Guide).
2.
3.
Fix OS
to do a basic operating system restore. The Fix OS screen
appears and displays two options (Back and Continue).
Click
Click
Continue
. The Installing Applications screen appears, showing the
status of the restore. It also displays the version of the Windows OS being
installed. The installation can take from 5 to 10 minutes.
Note: The drivers and other software components
required for the operating system are also loaded from the
CD.
After the OS finishes loading, the “Operating System Restore Completed”
screen appears.
4.
5.
Remove the CD from the CD tray.
Click
OK
to reboot.

This completes the OS Restore (or “Fix OS”) procedure. The system is now in a
state where data can be backed up. System settings previously located in the
C:\WINDOWS directory are now in a backup directory C:\WINDOWS.ORG.
!
CAUTION
Some or all applications might not exhibit full functionality
after the Fix OS is performed. To restore the system to its
factory-installed state, perform another OS Restore using
the Auto or Custom option.
!
CAUTION
Using the Fix OS option repetitively without using the Auto
or Custom option afterward might cause unpredictable
results.
To restore the system to its factory-installed state, perform another NEC OS
Restore using the Auto or Custom option (see “Launching the OS Restore CD”
in Chapter 3 of the PowerMate VT 300i Series User’s Guide).
PIIX4 Limitations
The following operating limitations apply to PIIX4 (PCI ISA IDE Xcelerator).
Reconfiguring Ultra DMA Support
The PCI IDE interface on the PowerMate VT 300i Series system supports the
latest ATA ULTRA DMA/33 interface. In order to do so, the PIIX4 component
that was recently released from Intel Corporation was incorporated in the
system. However, standard versions of Windows® 95 were released prior to the
release of PIIX4; these versions do not recognize the PIIX4 as capable of
supporting ULTRA DMA/33.
Several information files (.INF files) need to be added to standard versions of
Windows 95 so the operating system can incorporate PIIX4 features. NEC CSD
already includes these .INF files in the preinstalled software that comes with
your system. NEC CSD recommends that customers use the version of
Windows 95 that is included with their system.
Note: NEC CSD recommends that customers use the
version of Windows 95 that is included with their system
because this version is already configured for Ultra DMA/33.
NEC PowerMate VT 300i Series Release Notes A-9
Download from Www.Somanuals.com. All Manuals Search And Download.
When users install their own version of Windows 95, ULTRA DMA/33 does
not function without the addition of these files. These .INF files can be added to
a new install of Windows 95 by using the NEC OS Restore CD. This results in
full ULTRA DMA/33 support.
Determining IDE Device Compatibility
The new PIIX4 component contains a small change in the IDE interface. This
change to lower voltage levels on one signal has no effect on most of the IDE
hard drives on the market. A small number of older drives fail to function with
this new setting. If you have a concern about an older drive that you would like
to use with your PowerMate VT 300i Series system, NEC CSD Technical
Support Services can help you determine if there might be a problem.
New System Board Jumper Settings
The system board configuration label attached to the system chassis does not
contain a complete listing of jumper settings for this system. See the following
figure for updated jumper setup information.

Intel Processor Serial Number Control Utility
The Intel® Processor Serial Number Control utility is a Windows® program that
enables or disables the reading of the Pentium® III processor serial number by
software. This function lets you control which software programs or websites
have permission to read the processor serial number. When installed, the utility
runs automatically each time the system powers on.
This utility places an icon in the Windows system tray. The icon provides a
visual status of the processor serial number. You have the option of hiding the
system tray icon. You can disable the processor serial number at any time.
However, enabling the serial number requires restarting the system.
The following information describes:

Intel believes the processor serial number can provide compelling benefits to
users. They are developing features in conjunction with the processor serial
number to allow responsible service providers to provide services which
maintain your privacy. However, if you are concerned that a given
application/service using your processor number might impact your privacy, you
can turn off the processor serial number using the utility.
What is the default state of the processor serial number?
The default state of the processor serial number is on, until the Processor Serial
Number Control utility is installed. Once the Processor Serial Number Control
utility is installed, it turns the processor serial number off by default. You can
use the utility to turn on the processor serial number.
Can a website read my serial number without my knowledge?
No, generally not. Websites cannot read serial numbers unless you allow them
to download a program which can read the processor serial number. Almost all
browsers are configured to warn users whenever they download executable
software. Unless you disable the warning in the browser, you should receive a
notification.
Does Intel track serial numbers?
Generally not, other than related to the manufacturing process. Intel does not, in
the absences of advance and express consent of a user, collect serial number
data which is otherwise identified with a user.

Which programs and/or websites currently use the processor serial
number?
You can find a complete list of programs which can take advantage of the
processor serial number and other new capabilities of the Pentium III processor
at http://www.intel.com/pentiumiii/utility.htm.
How can I tell if my processor serial number is turned on?
The vast majority of Pentium III processor-based systems ship with the
processor serial number enabled. The control utility allows you to check the
status by:
Viewing the icon itself. The disabled icon shows a red circle with a
white “x.”
Clicking the task tray icon and selecting the “Status” menu item. Or you
can select the menu from the tool tip shown when you position the mouse
over the task tray icon.

Glossary
A
access time
The time period between the supply of an access signal and the output or
acceptance of the data by the addressed system. Examples are the access times for
DRAMs, SRAMs, hard drives, and CD-ROM drives. Hard drive access time is the
time it takes for a computer to get data from the drive. A hard drive with an 11 ms
access time is fast. A CD-ROM drive with a 280-ms access time is fast.
ACPI
Advanced Configuration and Power Interface. A power management specification
developed by Intel, Microsoft, and Toshiba. When installed on the system, ACPI
enables the operating system to control the amount of power given to each device
attached to the computer. With ACPI, the operating system can turn off peripheral
devices (such as CD-ROM drives) when they are not in use. As another example,
ACPI enables manufacturers to produce computers that automatically power up as
soon as you touch the keyboard.
adapter
An expansion board or component on the system board that communicates with
peripherals (such as the display monitor or network devices).
address
A hexadecimal number that represents a location in storage or memory. Also used
to identify communication ports. To communicate with a storage device.

Accelerated Graphics Port. A high-speed, high-performance video standard
supported by a dedicated connector on the system board. The connector allows the
connection of an AGP board to the system board’s AGP bus. AGP boards feature
64- or 128-bit graphics acceleration with an integrated digital video engine and
accelerated 3-D graphics, texture mapping, and shading functions. Fast refresh
rates, high resolution, and color depth allow for incredible graphics suitable for
multimedia and graphic intensive applications.
algorithm
Any set of instructions to be followed in order.
anti-aliasing
Making jagged edges look smoother by filling in the jags with an intermediate
color. Usually used in reference to the edges of shapes, especially letters, on a
computer screen.

API
Application Programming Interface. An API is a series of functions that programs
can use to make the operating system do routine or repetitive tasks. Using Windows
APIs, for example, a program can open windows, files, and message boxes (as well
as perform more complicated tasks) by passing a single instruction. Windows has
several classes of APIs that deal with telephony, messaging, and other issues.
APM
Advanced Power Management. An API developed by Intel and Microsoft that
allows developers to include power management in the BIOS. APM defines a layer
between the hardware and the operating system that effectively shields the
programmer from hardware details.
application programs
Software designed to perform specific functions or a group of functions, like
solving business or mathematical problems. Examples of applications include word
processing, communications, or database management.
architecture
A general term for the design and construction of computer systems, particularly
hardware, but also operating systems and networks. The circuitry within a chip is
called its architecture; for example, Intel architecture can refer to a computer based
on the Intel Celeron, Pentium II, or Pentium III chips.
archive
Copying one or more files to a different location for long-term data storage,
especially for backup and security purposes. Files can then be added to or deleted
from the archive. Also refers to the location where data is stored.
ASIC

circuit board, or for a very narrow range of use. The digital signal processor chip on
a modem is an ASIC.
asynchronous
Refers to operations that do not require the clocks of communicating devices to be
coordinated. Instead, the devices send signals to each other indicating readiness to
receive or send. Compare synchronous.
asynchronous cache

interleave,” a method of including a digital movie and its accompanying sound in
the same file. Files in the AVI format have the .AVI extension.
B
bad sector
Part of a hard drive or diskette drive storage medium that doesn’t hold data.
Formatting generally detects and marks these areas so they won’t be used. Certain
utility programs do, too, and it is a good idea to run this type of utility occasionally
to prevent data loss if the condition of the drive changes.
bandwidth
A measure of how much information something can carry. Specifically, data path
times frequency. For example, the ISA bus has a data path of 16 bits (it can send 16
bits at a time) and typically operates at 8.33 MHz, so it has a bandwidth of
133.28 megabits per second (Mbps).
base RAM
Area of system memory between 0 and 640 kilobytes available to the user for
operating system and application programs.
batch file
A file that contains a series of DOS commands. Batch files have the extension .bat.
If you execute a batch file, DOS attempts to carry out all the commands in the file,
in order.
baud
A unit of measure for modem speed. Literally, the number of voltage transitions per
second. Phone line limitations limit the actual baud rate of modems to 2400 baud,
although the data transmission rate (bps) may be higher because of data
compression.
BBS
Short for Bulletin Board Service. Software that serves as a communication and
information source for computers that communicate by modem.
BIOS
Basic Input/Output System. A program or set of programs permanently stored in
ROM chips installed on the system board. The BIOS contains functions that control
the real-time clock, keyboard, disk drives, video display, and other peripheral
devices. For example, the BIOS Setup utility program is contained in the BIOS, and
when you change the drive type, you change the BIOS.

bit
Binary digit. The smallest unit of computer data. A single digital piece of
information, generally represented by the numeral 0 or 1. Usually the transition
between the states of +5V and -5V within a computer, the charge of a transistor in
an integrated circuit, or the change in polarity of a magnetic region on a disk. See
byte. Data compression schemes can enable the transmission of more than one bit
per voltage transition.
bit block transfer
Moving part of a screen image as a single block rather than moving a pixel at a
time. Bit block transfers are much faster than moving the same pixels individually,
and it is common in accelerated video cards.
bitBLT
Bit Block Transfer.
bitmap
Any occurrence where a single location in memory and a single pixel correspond.
Usually applies to screen or printer output. .BMP files are bitmapped graphics files.
bits per second
(bps) A unit of transmission. Also called baud rate.
block
A contiguous section of bits considered as a whole, especially in memory. On a
disk, the data in one sector; in modem data transfer, the bits between checksums.
board
Printed circuit board. Board onto which computer components are soldered and thin
wires are printed to connect the components.
boot
To start up a computer. The computer is generally booted in one of three ways: by
turning on the power switch (cold boot), by pressing the reset switch, or by
simultaneously pressing the Ctrl, Alt, and Del keys (warm boot). Booting the
system after it has already been powered up and booted is referred to as rebooting.
Also the process of booting itself. Boot is from “bootstrap,” a reference to a
computer’s ability to set itself up, or pull itself up by its own ‘bootstraps.’ See cold
boot and warm boot.
bootable device
Any type of hardware that carries the information (software) required by the
computer to start properly. This device must also have the capacity to be
recognized by the computer in the first stages of the boot process.
boot block
The part of a disk that contains the software (such as the operating system loader)
that enables the computer to start.
4 Glossary
Download from Www.Somanuals.com. All Manuals Search And Download.
boot sector
The part of the boot block that contains the operating system loader, a program that
starts by itself and loads the operating system.
bps
Bits per second. The number of bits of data that can be transmitted in one second.
Because data compression schemes enable more than one bit per voltage transition,
bps is equivalent to baud only if no compression is used.
buffer
A place, especially in RAM, for the temporary storage of data for the purpose of
speeding up an operation such as printing or drive access. Data from a buffer is
available more quickly than data from where the buffer got it. Typically buffers get
data before it is needed so it is ready quickly when needed. Similar to cache.
burst mode
When a device seizes control of the bus, sends data, then relinquishes control of the
bus. Any time a device sends data without interruption instead of taking turns with
other devices.
bus
A parallel electrical pathway on the system board, connecting and shared by the
parts of a computer system (especially the CPU, its support circuitry, memory, and
expansion cards), used for transmitting data or electrical power from one device to
another. Typically the lines in a bus are dedicated to specific functions, such as
control lines, address lines, and data lines. Different bus architectures have different
numbers and arrangements of these lines, and different names (for example, ISA,
PCI). The most useful way of distinguishing bus architectures is by the number of
simultaneous data bits they can carry. The ISA is a 16-bit bus, while PCI is a 32-bit
bus.
bus master
The ability of an expansion card to control the bus without needing intervention
from the CPU.
byte
Group of eight contiguous bits. Frequently written as an eight-digit binary number
or a two-digit hexadecimal number. One letter of the alphabet in ASCII code takes
one byte.
C
cache
A special block of fast memory used for temporary storage of frequently used data
for quick retrieval. A memory cache, sometimes called a cache store or RAM
cache, is a portion of memory made of high-speed static RAM (SRAM) instead of
the slower and cheaper dynamic RAM (DRAM) used for system memory. Memory
caching is effective because most programs access the same data or instructions
over and over. By keeping as much of this information as possible in SRAM, the
computer avoids accessing the slower DRAM. See “write-back” and “write-
through.”

chassis
The metal frame to which the electronic components of the computer (such as the
system board, power supply, and drive bays) are attached. The chassis goes inside
the system unit cover.
checksum
A number, calculated from a block of data, used to verify the integrity of that data.
For example, a modem could send a block of data and include the number of 1’s
that occur in the block. The receiving modem could count the number of 1’s it
receives and compare its own number with the transmitted number. If the numbers
are the same, the transmission was probably OK.
clock
Electronic timer (oscillator) used to synchronize computer operations. The
oscillator generates the timing pulses that coordinate and enable the flow of data
within a digital device. Also a circuit powered by battery that keeps track of the
date and time for human and various system requirements.
clock speed
The frequency at which a clock oscillates. In microcomputers, measured in MHz.
The faster the clock, the faster the computer can compute.
CMOS
Complementary Metal Oxide Semiconductor. A chip on the system board that
contains nonvolatile memory. CMOS is backed up by an internal lithium battery
that preserves clock/calendar data and system configuration parameters stored in
CMOS.
codec
Coder-decoder. Used primarily with Internet phone and video conferencing
products, this software compresses digitized data and decompresses it at the other
end, allowing for faster data transfer and less delays
cold boot
Process of starting up the computer by turning on the power. If power is already on,
the process means to turn off the computer and turn it on again. A cold boot
reinitializes all devices.
compression
Any scheme for recording data with fewer bits. For example, stating how many
times something occurs can be shorter than stating each occurrence. It is shorter to
say “print a million white pixels” than to say “print white pixel number one, print
white pixel number two . . .”
D
default
The system’s factory setting for a specific device feature or system function. A
setting that a computer uses if it has not been modified by a user.

Kbps to 1.3 Mbps. One of the features of DVD drives is that they are backward-
compatible with CD-ROM disks. This means that DVD players can play old CD-
ROMs, CD-I disks, and video CDs, as well as new DVD-ROMs. Newer DVD
players can also read CD-R disks. DVD uses MPEG-2 to compress video data. See
MPEG.
E
ECC memory

into the drive and delivers high throughput.
interface
A connection that enables two devices to communicate.
interrupt
A signal from part of a system, such as an I/O device, asking to use the CPU.
Interrupts are hierarchical, which prevents interrupts from interrupting each other.
(Whichever interrupt has higher priority makes the other interrupt wait.) When the
CPU receives an interrupt signal, it saves what it is doing, processes the routine
associated with the interrupt, then returns to what it was doing.
I/O address

IRQ
Interrupt Request. A signal that, when received by the CPU, makes it stop what it is
going to do something else. An interrupt is a way in which a particular device in a
computer communicates with the CPU. PCs have 16 IRQ lines that can be assigned
to different devices (for example, printers, scanners, modems). No two devices can
have the same IRQ address. See interrupt.
ISA
Industry Standard Architecture. The bus architecture used in the IBM PC/XT and
PC/AT. The AT version of the bus is called the AT bus and has become an industry
standard. The apparent successor is the PCI local bus architecture found in most of
today’s computers. Most modern computers include both an AT bus for slower
devices and a PCI local bus for devices that need better bus performance. In 1993,
Intel and Microsoft introduced a new version of the ISA specification called Plug
and Play ISA. Plug and Play ISA enables the operating system to configure
expansion boards automatically so that users do not need to fiddle with DIP
switches and jumpers. See plug and play.

PCI
Peripheral Component Interface/Interconnect. A self-configuring personal
computer local bus designed by Intel. Most modern PCs include a PCI bus in
addition to a more general ISA expansion bus. PCI is a 32-bit bus, but supports a
64-bit extension for new processors, such as the Pentium II. It can run at clock
speeds of 33 or 66 MHz. At 32 bits and 33 MHz, it yields a throughput rate of
133 megabits per second. 64-bit implementations running at 66 MHz provide
524 Mbps. See ISA.
peripheral
Input or output device not under direct computer control. A printer is a peripheral
device.
pixels
Picture elements. Tiny dots that make up a screen image. A pixel is the smallest
spot on the screen that a computer can address.
plug and play
Refers to the ability of a computer system to automatically configure expansion
boards and other devices. This enables a user to plug in a device and use it, without
worrying about setting DIP switches, jumpers, and other configuration elements.

port
Any connection by which data can enter or leave a computer or peripheral.
Provides the means for an interface between the microprocessor and external
devices. A cable connector is usually plugged into the port to attach the device to
the computer.
processor
In a computer, a functional unit that interprets and executes instructions.
prompt
A special symbol indicating the beginning of an input line. Also a message that
appears on the screen indicating that the user must take a certain action.
R
RAM
Random Access Memory. A storage device into which data is entered and from
which data is retrieved in a nonsequential manner. On the system board, RAM is
semiconductor-based memory that can be read and written to by the microprocessor
or other hardware devices. In RAM, data can be directly and randomly read or
written (with any choice for the address). It’s the storage location for data that
needs to be immediately available for every application in use on your computer.
read
To extract data from a storage device such as a diskette.
ROM
Read-Only Memory. Memory in which stored data cannot be modified by the user
except under special conditions.
reset
The process of returning a device to zero or to an initial or arbitrarily selected
condition.
resolution
The degree of screen image clarity. Video display resolution is determined by the
number of pixels on the screen. Resolution is usually specified in pixels by scan
lines, for example, 640 by 480. See pixels.
RS-232C
Standard interface for serial devices.
S
SEC
Single-Edge Contact. The SEC cartridge containing the Pentium processor. See
Slot 1.
serial interface
An interface that communicates information one bit at a time.

serial printer
A printer with a serial interface.
SGRAM
Synchronous Graphic Random Access Memory. A type of DRAM used
increasingly on video adapters and graphics accelerators. Like SDRAM, SGRAM
can synchronize itself with the CPU bus clock at speeds of up to 100 MHz. In
addition, SGRAM uses several other techniques, such as masked writes and block
writes, to increase bandwidth for graphics-intensive functions. Unlike VRAM and
WRAM, SGRAM is single-ported (it can only be accessed by one device at a time).
However, it can open two memory pages at once, which simulates the dual-port
nature of other video RAM technologies (access by two different devices
simultaneously). See VRAM and WRAM.
SIMM
Single Inline Memory Module. A small circuit board holding a group of memory
chips. Typically, SIMMs hold up to nine RAM chips. On PCs, the ninth chip is for
parity error checking. Unlike memory chips, SIMMs are measured in bytes rather
than bits. In today’s SIMMs, each chip holds 2 MB, so a single SIMM holds 16
MB. SIMMs are easier to install than individual memory chips. The bus from a
SIMM to the actual memory chips is 32 bits wide. A newer technology, called dual
in-line memory module (DIMM), provides a 64-bit bus. To take advantage of the
64-bit bus on Pentium processors, use either DIMMs or pairs of SIMMs. See
DIMMs.
Slot 1
The form factor for Intel Pentium processors. The Slot 1 package replaces the
Socket 7 and Socket 8 form factors used by previous Pentium processors. Slot 1 is a
242-pin daughter card slot that accepts a processor packaged as a Single Edge
Contact (SEC) cartridge. A system board can have one or two Slot 1s. See SEC.
SMART
Self-Monitoring Analysis and Reporting Technology. A hard drive feature that
works in conjunction with system software (for example, LANDesk Client
Manager, NEC Auto Backup) for identifying a potential problem on the hard drive
and automatically backing up system files to a user-specified device, such as a tape
or Zip drive.
sound card
An expansion card designed for sound input and output. Sound cards can record
and play back digital audio. Most also have a MIDI synthesizer, which means they
can play MIDI files; some also have MIDI inputs and outputs.
super video graphics array (SVGA)
A color bit-mapped graphics display standard that provides a resolution of 1024x
768 with up to 256 colors displayed simultaneously.
synchronous
Refers to protocols that require the clocks of the communicating machines to be
coordinated.

system board
The main printed circuit board inside the system unit into which other boards and
major chip components, such as the system microprocessor, are connected.
T
tpi
Tracks per inch.
track
Any of many concentric circular regions on a disk for storing data. Tracks are
divided into sectors. One measure of storage density of a disk is tpi.
U
Ultra DMA
A protocol developed by Quantum Corporation and Intel that supports burst mode
data transfer rates of 33.3 MBps. This is twice as fast as the previous disk drive
standard for PCs, and is necessary to take advantage of new, faster Ultra ATA disk
drives. The official name for the protocol is Ultra DMA/33.
USB
Universal Serial Bus. An external bus standard that supports data transfer rates of
12 Mbps (12 million bits per second). A single USB port can be used to connect up
to 127 peripheral devices, such as mice, modems, and keyboards. USB also
supports Plug-and-Play installation and hot plugging. It is expected to eventually
replace serial and parallel ports.
V
VESA
Video Electronics Standards Association. The source of a SuperVGA standard used
on many video boards.
virus
Software that copies itself onto hard drives and diskettes without user intervention,
usually when a diskette is placed into the drive of a computer. Viruses usually
trigger a harmless or destructive occurrence on the system, activated by some preset
condition. Viruses are frequently written with antisocial intent.
VGA
Video Graphics Array. Graphics technology that supports up to 256 K colors and a
graphics resolution of 640 by 480 pixels.
volatile memory
Storage media that loses its data when system power is turned off. Standard
memory and memory added to the system are volatile memory. See nonvolatile
memory.

VRAM
Video RAM. VRAM is special-purpose memory used by video adapters. Unlike
conventional RAM, VRAM can be accessed by two different devices
simultaneously. This enables a video adapter to access the VRAM for screen
updates at the same time that the CPU provides new data. VRAM yields better
graphics performance but is more expensive than normal RAM. A special type of
VRAM, called Windows RAM (WRAM), yields even better performance than
conventional VRAM. See SGRAM and WRAM.
W
warm boot
Process of resetting the computer without turning off the power through keyboard
input (pressing Ctrl, Alt, and Del keys simultaneously) or the reset button. The
system returns to an initial or arbitrarily selected condition.
WRAM
Windows RAM. A type of RAM that supports two ports. This enables a video
adapter to fetch the contents of memory for display at the same time that new bytes
are being pumped into memory. This results in much faster display than is possible
with conventional single-port RAM. WRAM is similar to VRAM, but achieves
even faster performance at less cost because it supports addressing of large blocks
(windows) of video memory. See VRAM and SGRAM.
write
To record or store information to a storage device.
write-back
Also called copy back. A cache strategy where write operations to data stored in the
internal microprocessor L1 cache aren’t copied to system memory until absolutely
necessary. In contrast, a write-through cache performs all write operations in
parallel; data is written to system memory and the L1 cache simultaneously. Write-
back caching yields somewhat better performance than write-through caching
because it reduces the number of write operations to main memory. See cache and
write-through.
write-through
Also write-thru. Write-through characterizes a cache strategy where data is always
written into system memory when data is written by the CPU. See cache and write
back.
