II. FEATURES
ASUS TX97 Smart Series Motherboards
Performance
•
SDRAM Optimized Performance - ASUS TX97 smart series motherboards
support the new generation memory - Synchronous Dynamic Random Access
Memory (SDRAM) which increases the data transfer rate from 264MB/s max
using EDO memory to 528MB/s max using SDRAM.
•
Double the IDE Transfer Speed - ASUS TX97 smart series motherboards with
Intel 430TX PCIset improves IDE transfer rate using Bus Master UltraDMA/33
IDE which can handle data transfer up to 33MB/s. The best of all is that this
new technology is compatible with existing ATA-2 IDE specs so there is no
need to upgrade current hard drives or cables.
•
Concurrent PCI - Concurrent PCI allows multiple PCI transfers from PCI master
busses to memory to CPU.
•
ACPI Ready - ACPI (Advanced Configuration and Power Interface) is also
implemented on all ASUS 430TX series of motherboards. ACPI provide more
Energy Saving Features for the future operating systems (OS) supporting OS
Direct Power Management (OSPM) functionality. With these features imple-
mented in the OS, PCs can be ready around the clock everyday, yet satisfy all
the energy saving standards. To fully utilize the benefits of ACPI, an ACPI-
supported OS such as in the next release of Windows 95 must be used.
•
PC ’97 Compliant - Both the BIOS and hardware levels of ASUS TX97 series
of motherboards meet PC ’97 compliancy. The new PC 97 requirements for
systems and components are based on the following high-level goals: Support
for Plug and Play compatibility and power management for configuring and
managing all system components, and 32-bit device drivers and installation pro-
cedures for both Windows 95 and Windows NT.
Intelligence: (with optional LM78/75 Hardware Monitor only)
•
Fan Status Monitoring and Alarm - To prevent system overheat and system
damage, the CPU fan and system fans are monitored for RPM and failure. Each
fan can be set for its normal RPM range and alarm thresholds.
•
Temperature Monitoring and Alert - To prevent system overheat and system
damage, there is a heat sensor under the CPU and on the motherboard itself to
monitor CPU and system temperature to make sure the system is operating at a
safe heat level to avoid any failures triggered by extremely high temperature.
ASUS TX97-XE User’s Manual

II. FEATURES
Voltage Monitoring and Alert: System voltage levels are monitored to ensure
stable current to critical motherboard components. Voltage specifications are
more critical for future processors, so monitoring is necessary to ensure proper
system configuration and management.
•
•
System ResourcesAlert: Today’s operating systems such as Windows 95, Win-
dows NT, and OS/2, require much more memory and hard drive space to present
enormous user interfaces and run large applications. The system resource moni-
tor will warn the user before the system resources are used up to prevent pos-
sible application crashes. Suggestions will give the user information on manag-
ing their limited resources more efficiently.
•
•
Virus Write Protection - Normally, viruses can destroy data on storage media
such as hard drivers, floppy diskettes, and MO. Some new-generation viruses
will not only destroy data on storage media, but also clear BIOS data which is
usually unprotected. ASUS TX97 series of motherboards were designed to co-
operate with BIOS, chipset, and flash EPROM to disable write permission when
the system’s initialization stage is completed upon boot-up.
CPU Slow Down - When CPU fans or system fans are malfunctioning, the
system will deactivate the CPU Clock line to decrease CPU utilization to the
speed upon detection of system overheat. This will prevent CPU damage from
system overheat. The CPU utilization will restore normal operations when tem-
perature falls below a safe level.
•
•
Auto Fan Off - The system fans will power off automatically even in sleep
mode. This function reduces both energy consumption and system noise, and
is a important feature to implement silent PC systems.
Dual Function Power Button (requires ATX power supply): The system can
be in one of two states, one is Sleep mode and the other is the Soft-Off mode.
Pushing the power button for less than 4 seconds places the system into Sleep
mode. When the power button is pressed for more than 4 seconds, it enters the
Soft-Off mode.
•
•
Remote Ring On (requires external modem and ATX power supply): This
allows a computer to be turned on remotely through an external modem. With this
benefit on-hand, any user can access vital information from their computer from
anywhere in the world!
Message LED (requires ACPI OS support): Chassis LEDs now act as infor-
mation providers. Through the way a particular LED illuminates, the user can
determine the stage the computer is in. A simple glimpse provides useful infor-
mation to the user.

III. INSTALLATION
Installation Steps
Before using your computer, you must complete the following steps:
1. Set Jumpers on the Motherboard
2. Install System Memory Modules
3. Install the Central Processing Unit (CPU)
4. Install Expansion Cards
5. Connect Ribbon Cables, Cabinet Wires, and Power Supply
6. Setup the BIOS Software
1. Jumpers
Several hardware settings are made through the use of jumper caps to connect jumper
pins (JP) on the motherboard. See motherboard layout for locations of jumpers. The
jumper settings will be described numerically, such as [----], [1-2], [2-3] for no con-
nection, connect pins 1&2, and connect pins 2&3 respectively. Pin 1 for our mother-
PIN 1
PIN 1
boards is always on top
the keyboard connector away from yourself. A“1” is written besides pin 1 on jumpers
with three pins. The jumpers will also be shown graphically such as to connect
pins 1&2 and to connect pins 2&3. Jumpers with two pins will be shown as
for Short (On) and for Open (Off). For manufacturing simplicity, the jump-
or on the left
when holding the motherboard with
ers may be sharing pins from other groups. Use the diagrams in this manual instead of
following the pin layout on the board. Settings with two jumper numbers require that
both jumpers be moved together. To connect the pins, simply place a plastic jumper
cap over the two pins as diagramed.
WARNING! Computer motherboards, baseboards and components, such as SCSI
cards, contain very delicate Integrated Circuit (IC) chips. To protect them against
damage from static electricity, you should follow some precautions whenever you
work on your computer.
1. Unplug your computer when working on the inside.
2. Use a grounded wrist strap before handling computer components. If you do
not have one, touch both of your hands to a safely grounded object or to a
metal object, such as the power supply case.
3. Hold components by the edges and try not to touch the IC chips, leads or
connectors, or other components.
4. Place components on a grounded antistatic pad or on the bag that came with
the component whenever the components are separated from the system.

2. System Memory (SIMM & DIMM)
This motherboard supports four 72-pin, 32-bit SIMMs (Single Inline Memory Mod-
ules) of 4, 8, 16, 32, or 64MB to form a memory size between 8MB to 256MB. The
SIMMs can be either 60ns or 70ns Fast Page Mode (FPM) (Asymmetric or Sym-
metric), or Enhanced Data Out (EDO) (BEDO & Parity are not supported). SIMMs
must be installed in pairs so that each Row (see Map of Motherboard for Row loca-
tions) contains 64-bits of the same size and type of memory chips. One side (with
memory chips) of the SIMM module takes up half a Row on the motherboard.
Dual Inline Memory Modules (DIMMs) can be used when the SIMM sockets are
not used. Two sockets are available for 3.3Volt (power level) Unbuffered Synchro-
nous DRAMs (SDRAM) or EDO DRAM of either 8, 16, 32, 64, or 128MB to form
a memory size between 8MB to 256MB. One side (with memory chips) of the
DIMM module takes up one row on the motherboard.
IMPORTANT: Memory speed setup is required through “Auto Configuration”
in BIOS Chipset Setup of the BIOS SOFTWARE. If both 60ns and 70ns memory
are used, set “Auto Configuration” to 70ns. Do not use memory modules with
more than 24 chips per module. Modules with more than 24 chips exceed the
design specifications of the memory subsystem and will be unstable.

3. Central Processing Unit (CPU)
The motherboard provides a 321-pin ZIF Socket 7 that is backwards compatible
with ZIF Socket 5 processors. The CPU that came with the motherboard should
have a fan attached to it to prevent overheating. If this is not the case then purchase
a fan before you turn on your system. Apply thermal jelly to the CPU top and then
install the fan onto the CPU.
WARNING! Without a fan circulating air on the CPU and heat sinks, the CPU
and/or heat sinks can overheat and cause damage to both the CPU and the moth-
erboard. (See “CPU Cooling Fan Connector” at the end of this section.)
To install a CPU, first turn off your system and remove its cover. Locate the ZIF
socket and open it by first pulling the lever sideways away from the socket then
upwards to a 90-degree right angle. Insert the CPU with the correct orientation as
shown. Use the notched corner of the CPU as your guide. The white dot should
point towards the end the of the lever. Notice that there is a blank area where one
hole is missing from that corner of the square array of pin holes and a “1” printed on
the motherboard next to that corner. Because the CPU has a corner pin for three of
the four corners, the CPU will only fit in the one orientation as shown. The picture
is for reference only; you should have a CPU fan that will cover the face of the CPU.
With the added weight of the CPU fan, no force is required to insert the CPU. Once
completely inserted, hold down on the fan and close the socket’s lever.
IMPORTANT: You must set jumpers for “CPU to BUS Frequency Ratio” and
jumpers for “BUS Frequency Selection” depending on the CPU that you install.

4. Expansion Cards
WARNING! Make sure that you unplug your power supply when adding or
removing expansion cards or other system components. Failure to do so may
cause severe damage to both your motherboard and expansion cards.
Expansion Card Installation Procedure:
1. Read your expansion card documentation on any hardware and software set-
tings that may be required to setup your specific card.
2. Set any necessary jumpers on your expansion card.
3. Remove your computer system’s cover.
4. Remove the bracket on the slot you intend to use.
Keep the bracket for possible future use.
5. Carefully align the card’s connectors and press firmly.
6. Secure the card on the slot with the screw you removed in step 4.
7. Replace the computer system’s cover.
8. Edit the BIOS settings if necessary.
(such as “IRQ xx Used By ISA: Yes” in PNP AND PCI SETUP)
9. Install the necessary software drivers for your expansion card.
Assigning IRQs for Expansion Cards
Some expansion cards need to use an IRQ to operate. Generally an IRQ must be
exclusively assigned to one use. In an standard design there are 16 IRQs available
but most of them are already in use by parts of the system which leaves 6 free for
expansion cards.
Both ISA and PCI expansion cards may need to use IRQs. System IRQs are avail-
able to cards installed in the ISA expansion bus first, and any remaining IRQs are
then used by PCI cards. Currently, there are two types of ISA cards. The original
ISA expansion card design, now referred to as “Legacy” ISA cards, requires that
you configure the card’s jumpers manually and then install it in any available slot on
the ISA bus. You may use Microsoft’s Diagnostic (MSD.EXE) utility included in
the Windows directory to see a map of your used and free IRQs. For Windows 95
users, the “Control Panel” icon in “My Computer,” contains a “System” icon which
gives you a “Device Manager” tab. Double clicking on a specific device gives you
the “Resources” tab, which shows the Interrupt number and address. Make sure that
no two devices use the same IRQs or your computer will experience problems when
those two devices are in use at the same time.
ASUS TX97-XE User’s Manual
23
III. INSTALLATION
To simplify this process this motherboard has complied with the Plug and Play (PNP)
specification which was developed to allow automatic system configuration when-
ever a PNP-compliant card is added to the system. For PNP cards, IRQs are as-
signed automatically from those available.
If the system has both Legacy and PNP ISA cards installed, IRQs are
assigned to PNP cards from those not used by Legacy cards. The PCI and PNP
configuration of the BIOS setup utility can be used to indicate which IRQs are being
used by Legacy cards. For older Legacy cards that does not work with the BIOS,
you can contact your vendor for an ISA Configuration Utility.
An IRQ number is automatically assigned to PCI expansion cards after those used
by Legacy and PNP ISA cards. In the PCI bus design, the BIOS automatically
assigns an IRQ to a PCI slot that has a card in it that requires an IRQ. To install a
PCI card, you need to set something called the INT (interrupt) assignment. Since all
the PCI slots on this motherboard use an INTA #, be sure that the jumpers on your
PCI cards are set to INT A.
Assigning DMA Channels for ISA Cards
Some ISAcards, both legacy and PnP, may also need to use a DMA(Direct Memory
Access) channel. DMA assignments for this motherboard are handled the same way
as the IRQ assignment process described earlier. You can select a DMA channel in
the PCI and PnP configuration section of the BIOS Setup utility.
IMPORTANT: To avoid conflicts, reserve the necessary IRQs and DMAs for legacy
ISA cards (under PNPAND PCI SETUP of the BIOS SOFTWARE, choose Yes in IRQ
xx Used By ISA and DMA x Used By ISA for those IRQs and DMAs you want to reserve).
ISA Cards and Hardware Monitor
The onboard hardware monitor uses the address 290H-297H so legacy ISA cards
must not use this address or else conflicts will occur.

2. Be sure that all switches are off (in some systems, marked with ).
3. Connect the power supply cord into the power supply located on the back of
your system case according to your system user’s manual.
4. Connect the power cord into a power outlet that is equipped with a surge protector.
5. You may then turn on your devices in the following order:
a. Your monitor
b. External SCSI devices (starting with the last device on the chain)
c. Your system power. For ATX power supplies, you need to switch
on the power supply as well as press the ATX power switch on the
front of the case.
6. The power LED on the front panel of the system case will light. ForATX power
supplies, the system LED will light when theATX power switch is pressed. The
monitor LED may light up after the system’s if it complies with “green” stan-
dards or if it has a power standby feature. The system will then run power-on
tests. While the tests are running, additional messages will appear on the screen.
If you do not see anything within 30 seconds from the time you turn on the
power, the system may have failed a power-on test. Recheck your jumper set-
tings and connections or call your retailer for assistance.
7. During power-on, hold down <Delete> to enter BIOS setup. Follow the instruc-
tions in the next section, BIOS SOFTWARE.
* Powering Off your computer: You must first exit or shut down your operating
system before switching off the power switch. For ATX power supplies, you
can press the ATX power switch after exiting or shutting down your operating
system. If you use Windows 95, click the Start button, click Shut Down, and
then click Shut down the computer?. The system will give three quick beeps
after about 30 seconds and then power off after Windows shuts down.
NOTE: The message “You can now safely turn off your computer” will not
appear when shutting down with ATX power supplies.

AFLASH.EXE: This is the Flash Memory Writer utility that updates the BIOS by uploading
a new BIOS file to the programmable flash ROM chip on the motherboard. To determine the
BIOS version of your motherboard, check the last four numbers of the code displayed on the
upper left-hand corner of your screen during bootup. Larger numbers represent a newer BIOS
file. This file works only in DOS mode.
NOTE: The following screen displays are provided as examples only and may not reflect the
screen contents displayed on your system.
Flash Memory Writer Utility
IMPORTANT! If “unknown” is displayed after Flash Memory:, the memory chip is
either not programmable or is not supported by the ACPI BIOS and therefore, cannot
be programmed by the Flash Memory Writer utility.

Managing and Updating Your Motherboard’s BIOS
Upon First Use of the Computer System
1. Create a bootable system floppy disk by typing [FORMAT A:/S] from the DOS
prompt without creating “AUTOEXEC.BAT” and “CONFIG.SYS” files.
2. Copy AFLASH.EXE to the just created boot disk.
3. RunAFLASH.EXE from this new disk and select option 1. Save Current BIOS
to File. See 1. Save Current BIOS To File on the previous page for more de-
tails and the rest of the steps.
Updating BIOS Procedures (only when necessary)
1. Download an updated ASUS BIOS file from the Internet (WWW or FTP) or a
BBS (Bulletin Board Service) (seeASUS CONTACT INFORMATION on page
3 for details) and save to the disk you created earlier.
2. Boot from the disk you created earlier.
3. At the “A:\” prompt, type AFLASH and then press <Enter>.
4. At the Main Menu, type 2 and then press <Enter>. See 2. Update BIOS In-
cluding Boot Block and ESCD on the previous page for more details and the
rest of the steps.
WARNING! If you encounter problems while updating the new BIOS, DO NOT
turn off your system since this might prevent your system from booting up. Just
repeat the process, and if the problem still persists, update the original BIOS file
you saved to disk above. If the Flash Memory Writer utility was not able to
successfully update a complete BIOS file, your system may not be able to boot
up. If this happens, your system will need service.

6. BIOS Setup
The motherboard supports two programmable Flash ROM chips: 5 Volt and 12 Volt.
Either of these memory chips can be updated when BIOS upgrades are released.
Use the Flash Memory Writer utility to download the new BIOS file into the ROM
chip as described in detail in this section.
All computer motherboards provide a Setup utility program for specifying the sys-
tem configuration and settings. If your motherboard came in a computer system, the
proper configuration entries may have already been made. If so, invoke the Setup
utility, as described later, and take note of the configuration settings for future refer-
ence; in particular, the hard disk specifications.
If you are installing the motherboard, reconfiguring your system or you receive a
Run Setup message, you will need to enter new setup information. This section
describes how to configure your system using this utility.
The BIOS ROM of the system stores the Setup utility. When you turn on the com-
puter, the system provides you with the opportunity to run this program. This ap-
pears during the Power-On Self Test (POST). Press <Delete> to call up the Setup
utility. If you are a little bit late pressing the mentioned key(s), POST will continue
with its test routines, thus preventing you from calling up Setup. If you still need to
call Setup, reset the system by pressing <Ctrl> + <Alt> + <Delete>, or by pressing
the Reset button on the system case. You can also restart by turning the system off
and then back on again. But do so only if the first two methods fail.
When you invoke Setup, the CMOS SETUP UTILITY main program screen will
appear with the following options:

Load Defaults
The Load BIOS Defaults option loads the minimum settings for troubleshooting.
Load Setup Defaults, on the other hand, is for loading optimized defaults for regu-
lar use. Choosing defaults at this level will modify all applicable settings.
A section at the bottom of the preceding screen displays the control keys for this
screen. Take note of these keys and their respective uses.
Standard CMOS Setup
Standard CMOS Setup allows you to record some basic system hardware configu-
ration and set the system clock and error handling. If the motherboard is already
installed in a working system, you will not need to select this option anymore. How-
ever, if the configuration stored in the CMOS memory on the board gets lost or
damaged, or if you change your system hardware configuration, you will need to
respecify the configuration values. The configuration values usually get lost or
corrupted when the power of the onboard CMOS battery weakens.
The preceding screen provides you with a list of options. At the bottom of this screen
are the control keys. Take note of these keys and their respective uses.
User-configurable fields appear in a different color. If you need information on the
selected field, press <F1>. The help menu will then appear to provide you with the
information you need. The memory display at the lower right of the screen is read-
only and automatically adjusts accordingly.
Details of Standard CMOS Setup:
Date
To set the date, highlight the “Date” field and then press either <Page Up>/<Page Down>
or <+>/<–> to set the current date. Follow the month, day and year format. Valid values
for month, day and year are: Month: (1 to 12), Day: (1 to 31), Year: (up to 2079)

Time
To set the time, highlight the “Time” field and then press either <Page Up>/<Page Down>
or <+>/<–> to set the current time. Follow the hour, minute and second format. Valid
values for hour, minute and second are: (Hour: (00 to 23), Minute: (00 to 59), Second:
(00 to 59). If you do not want to modify the current time, press <Enter> three times
to go to Hard Disks.
NOTE: You can bypass the date and time prompts by creating anAUTOEXEC.BAT
file. For information on how to create this file, refer to the MS-DOS manual.
Hard Disk Drives
This field records the specifications for all non-SCSI hard disk drives installed in
your system. The onboard PCI IDE connectors provide Primary and Secondary
channels for connecting up to four IDE hard disks or other IDE devices. Each chan-
nel can support up to two hard disks; the first of which is the “master” and the
second is the “slave”.
Specifications for SCSI hard disks need not to be entered here since they operate
using device drivers and are not supported by any the BIOS. If you install either the
optional PCI-SC200 or PCI-SC860 SCSI controller card into the motherboard, see
section VI for instructions. If you install other vendor’s SCSI controller card, refer
to their respective documentations on how to install the required SCSI drivers.
For IDE hard disk drive setup, you can:
•
•
Use the Auto setting for detection during bootup.
Use the IDE HDD AUTO DETECTION in the main menu to automatically
enter the drive specifications.
•
Enter the specifications yourself manually by using the “User” option.
The entries for specifying the hard disk type include CYLS (number of cylinders),
HEAD (number of read/write heads), PRECOMP (write precompensation), LANDZ
(landing zone), SECTOR (number of sectors) and MODE. The SIZE field auto-
matically adjusts according to the configuration you specify. The documentation
that comes with your hard disk should provide you with the information regarding
the drive specifications.
The MODE entry is for IDE hard disks only, and can be ignored for MFM and ESDI
drives. This entry provides three options: Normal, Large, LBA, or Auto (see below).
Set MODE to the Normal for IDE hard disk drives smaller than 528MB; set it to
LBA for drives over 528MB that support Logical Block Addressing (LBA) to allow
larger IDE hard disks; set it to Large for drives over 528MB that do not support
LBA. Large type of drive can only be used with MS-DOS and is very uncommon.
Most IDE drives over 528MB support the LBA mode.

Auto detection of hard disks on bootup
For each field: Primary Master, Primary Slave, Secondary Master, and Secondary
Slave, you can select Auto under the TYPE and MODE fields. This will enable auto
detection of your IDE hard disk during bootup. This will allow you to change your
hard disks (with the power off) and then power on without having to reconfigure
your hard disk type. If you use older hard disks that do not support this feature, then
you must configure the hard disk in the standard method as described earlier by the
“User” option.
NOTE: After the IDE hard disk drive information has been entered into BIOS, new
IDE hard disk drives must be partitioned (such as with FDISK) and then formatted
before data can be read from and write on. Primary IDE hard disk drives must have
its partition set to active (also possible with FDISK).
NOTE: SETUP Defaults are noted in parenthesis next to each function heading.
Drive A / Drive B (None)
These fields record the types of floppy disk drives installed in your system. The
available options for drives A and B are: 360KB, 5.25 in.; 1.2MB, 5.25 in.; 720KB,
3.5 in.; 1.44MB, 3.5 in.; 2.88MB, 3.5 in.; None
To enter the configuration value for a particular drive, highlight its corresponding
field and then select the drive type using the left- or right-arrow keys.
Floppy 3 Mode Support (Disabled)
This is the Japanese standard floppy drive. The standard stores 1.2MB in a 3.5inch
diskette. This is normally disabled but you may choose from either: Drive A, Drive
B, Both, and Disabled
Video (EGA/VGA)
Set this field to the type of video display card installed in your system. The options
are EGA/VGA, CGA 49, CGA 80, and Mono (for Hercules or MDA).
If you are using a VGA or any higher resolution card, choose EGA/VGA.
Halt On (All Errors)
This field determines which types of errors will cause the system to halt. Choose from
All Errors; No Errors; All,But Keyboard, All,But Diskette; and All,But Disk/Key.

BIOS Features Setup
BIOS Features Setup consists of configuration entries that allow you to improve
your system performance, or let you set up some system features according to your
preference. Some entries are required by the motherboard’s design to remain in
their default settings.
Asection at the lower right of the screen displays the control keys you can use. Take
note of these keys and their respective uses. If you need information on a particular
entry, highlight it and then press <F1>. A pop-up help menu will appear to provide
you with the information you need. <F5> loads the last set values, <F6> and <F7>
loads the BIOS default values and Setup default values, respectively.
NOTE: SETUP Defaults are noted in parenthesis next to each function heading.

Virus Warning (Disabled)
This field protects the boot sector and partition table of your hard disk against accidental
modifications. Any attempt to write to them will cause the system to halt and display a
warning message. If this occurs, you can either allow the operation to continue or use a
bootable virus-free floppy disk to reboot and investigate your system. This setting is rec-
ommended because of conflicts with new operating systems or some programs. Installa-
tion of these programs requires that you disable Virus Warning to prevent write errors.
CPU Internal Cache (Enabled)
Choose Disable to turn off the CPU’s built-in level 1 cache.
External Cache (Enabled)
Choose Disable to turn off the CPU’s external level 2 cache (Pentium Pro is built-in).
Quick Power On Self Test (Enabled)
This field speeds up the Power-On Self Test (POST) routine by skipping retesting a
second, third, and forth time. Setup default setting for this field is Enabled. A com-
plete test of the system is done on each test.

HDD Sequence SCSI/IDE First (IDE)
When using both SCSI and IDE hard disk drives, IDE is always the boot disk using
drive letter C (default setting of IDE). This new feature allows a SCSI hard disk
drive to be the boot disk when set to SCSI. This allows multiple operating systems to
be used on both IDE and SCSI drives or the primary operating system to boot using
a SCSI hard disk drive.
Boot Sequence (C,A)
This field determines where the system looks first for an operating system. Options are
C,A; A,CDROM,C; CDROM,C,A; D,A; E,A; F,A; C only; LS/ZIP, C; and A,C. The setup
default setting is to check first the hard disk and then the floppy disk drive; that is, C, A.
Boot Up Floppy Seek (Disabled)
When enabled, the BIOS will seek drive A one time.
Floppy Disk Access Control (R/W)
This allows protection of files from the computer system to be copied to floppy disk
drives by allowing the setting of Read Only to only allow reads from the floppy disk
drive but not writes. The setup default R/W allows both reads and writes.
IDE HDD Block Mode Sectors (HDD MAX)
This field enhances hard disk performance by making multi-sector transfers instead
of one sector per transfer. Most IDE drives, except older versions, can utilize this
feature. Selections are HDD MAX, Disabled, 2, 4, 8, 16, and 32.
Security Option (System)
This field determines when the system prompts for the password. The default set-
ting is System, where the system prompts for the User Password every time you boot
up. The other option is Setup, where the system always boots up, and prompts for
the Supervisor Password only when the Setup utility is called up. You can specify a
password by using the Supervisor Password or User Password option from the main
screen as explained later in this section.
PS/2 Mouse Function Control (Auto)
The default of Auto allows the system to detect a PS/2 mouse on bootup. If detected,
IRQ12 will be used for the PS/2 mouse. IRQ12 will be reserved for expansion cards
if a PS/2 mouse is not detected. Enabled will reserve IRQ12 for the PS/2 mouse, and
thus other devices will not be able to use IRQ12.
PCI/VGA Palette Snoop (Disabled)
Some display cards that are nonstandard VGAsuch as graphics accelerators or MPEG
Video Cards may not show colors properly. The setting Enabled should correct this
problem. Otherwise leave this on the setup default setting of Disabled.
OS/2 Onboard Memory > 64M (Disabled)
When using OS/2 operating systems with installed DRAM of greater than 64MB,
you need to Enable this option otherwise leave this on the setup default of Disabled.

Video ROM BIOS Shadow (Enabled)
This field allows you to change the video BIOS location from ROM to RAM. Relocat-
ing to RAM enhances system performance, as information access is faster than the ROM.
C8000 - CBFFF Shadow to DC000 - DFFFF Shadow (Disabled)
These fields are used for shadowing other expansion card ROMs. If you install other
expansion cards with ROMs on them, you will need to know which addresses the
ROMs use to shadow them specifically. Shadowing a ROM reduces the memory
available between 640KB and 1024KB by the amount used for this purpose.
Boot Up NumLock Status (On)
This field enables users to activate the Number Lock function upon system boot.
Typematic Rate Setting (Disabled)
When enabled, you can set the two typematic controls listed next. Setup default
setting is Disabled.
Typematic Rate (Chars/Sec) (6)
This field controls the speed at which the system registers repeated keystrokes. Op-
tions range from 6 to 30 characters per second. Setup default setting is 6; other
settings are 8, 10, 12, 15, 20, 24, and 30.
Typematic Delay (Msec) (250)
This field sets the time interval for displaying the first and second characters. Four
delay rate options are available: 250, 500, 750, and 1000.
