2. FEATURES  
2.1.2 Special Features  
ACPI Ready: Advanced Configuration Power Interface (ACPI) provides more  
Energy Saving Features for operating systems that support OS Direct Power  
Management (OSPM) functionality. With these features implemented in the OS,  
PCs can be ready around the clock, yet satisfy all the energy saving standards.  
To fully utilize the benefits of ACPI, an ACPI-supported OS such as Windows  
98 must be used.  
Easy Installation: Incorporates BIOS that supports autodetection of hard disk  
drives, PS/2 mouse, and Plug and Play devices to make the setup of hard disk  
drives, expansion cards, and other devices virtually automatic.  
New Compliancy: Both the BIOS and hardware levels of this motherboard meet  
the stringent requirements for PC99 certification. The new PC99 requirements  
for systems and components are based on the following high-level goals: Sup-  
port for Plug and Play compatibility and power management for configuring  
and managing all system components, and 32-bit device drivers and installation  
procedures for Windows95/98/NT . Color-coded connectors and descriptive icons  
make identification easy as required by PC99.  
Symbios SCSI BIOS: Supports optional ASUS SCSI controller cards through  
the onboard SYMBIOS firmware.  
2.1.3 Performance Features  
Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-  
ter busses to the memory and processor.  
SDRAM Optimized Performance: Supports the new generation memory - Syn-  
chronous Dynamic RandomAccess Memory (SDRAM) which increases the data  
transfer rate to 800MB/s max using PC100-compliant SDRAM.  
High-Speed Data Transfer Interface: The CUBX-L motherboard supports  
UltraDMA/33 and can handle data transfer rates up to 33MB/s. The CUBX-E  
motherboard supports UltraDMA/100, which increases the data transfer rate to  
100MB/s. UltraDMA/100 is backward compatible with DMA/66, DMA/33, and  
DMA and with existing DMA devices and systems so there is no need to up-  
grade current EIDE/IDE drives and host systems. (UltraDMA/66 and UltraDMA/  
100 require a 40-pin 80-conductor cable to be enabled.)

2. FEATURES  
2.1.4 Intelligence  
Dual Function Power Button: Pushing the power button for less than 4 sec-  
onds when the system is in the working state places the system into one of two  
states: sleep mode or soft-off mode, depending on the BIOS or OS setting (see  
PWR Button < 4 Secs in 4.5 Power Menu). When the power button is pressed  
for more than 4 seconds, the system enters the soft-off mode regardless of the  
BIOS setting.  
Fan Status Monitoring and Alarm: To prevent system overheat and system  
damage, the CPU, power supply, and system fans can be monitored for RPM  
and failure. All fans are set for its normal RPM range and alarm thresholds.  
Message LED (requires ACPI OS support): Turbo LEDs now act as informa-  
tion providers. Through the way a particular LED illuminates, the user can de-  
termine if a message has been received from a fax/modem. A simple glimpse  
provides useful information to the user.  
Remote Ring On (requires modem): This allows a computer with this mother-  
board to be turned on remotely through an internal or external modem. With this  
feature, users can access their computers from anywhere in the world!  
System Resources Alert: Todays operating systems such as Windows 95/98/  
NT and OS/2, require much more memory and hard drive space to present enor-  
mous user interfaces and run large applications. The system resource monitor  
will warn the user before the system resources are used up to prevent possible  
application crashes. Suggestions will give the user information on managing  
their limited resources more efficiently.  
Voltage Monitoring and Alert: System voltage levels are monitored to ensure  
stable voltage to critical motherboard components. Voltage specifications are  
more critical for future processors, so monitoring is necessary to ensure proper  
system configuration and management.

This section explains in detail how to change your motherboards function settings  
through the use of switches and/or jumpers.  
WARNING! Computer motherboards and expansion cards contain very delicate  
Integrated Circuit (IC) chips. To protect them against damage from static electric-  
ity, 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.  
WARNING! Make sure that you unplug your power supply when adding or  
removing system components. Failure to do so may cause severe damage to  
your motherboard, peripherals, and/or components. The onboard LED when lit  
acts as a reminder that the system is in suspend or soft-off mode and not powered

3.5 System Memory (DIMM)  
NOTE: No hardware or BIOS setup is required after adding or removing memory.  
This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are  
available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Ac-  
cess Memory (SDRAM). One side (with memory chips) of the DIMM takes up one  
row on the motherboard.  
To utilize the chipsets Error Checking and Correction (ECC) feature, you must use a  
DIMM module with 9 chips per side (standard 8 chips/side + 1 ECC chip).  
Memory speed setup is recommended through SDRAM Configuration in 4.4.1  
Chip Configuration.

3.5.1 General DIMM Notes  
For the system CPU bus to operate at 100MHz, use only PC100-compliant  
DIMMs. When this motherboard operates at 100MHz, most system will not  
even boot if non-compliant modules are used because of the strict timing issues  
involved under this speed. If your DIMMs are not PC100-compliant, set the  
CPU bus frequency to 66MHz RAM to ensure system stability.  
ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the  
memory of choice for best performance vs. stability.  
Two possible memory chips are supported: SDRAM with and without ECC.  
SDRAM chips are generally thinner with higher pin density than EDO (Ex-  
tended Data Output) chips.  
BIOS shows SDRAM memory on bootup screen.  
Single-sided DIMMs come in 16, 32, 64,128MB; double-sided come in 32, 64,  
128, 256MB.

WARNING! Make sure that you unplug your power supply when adding or  
removing memory modules or other system components. Failure to do so may  
cause severe damage to both your motherboard and expansion cards (see 3.3  
Hardware Setup Procedure for more information).  
Insert the module(s) as shown. Because the number of pins are different on either  
side of the breaks, the module will only fit in the orientation shown. DRAM SIMM  
modules have the same pin contacts on both sides. SDRAM DIMMs have different  
pin contacts on each side and therefore have a higher pin density.

The DIMMs must be 3.3Volt unbuffered SDRAMs. To determine the DIMM type,  
check the notches on the DIMMs (see figure below).  
The notches on the DIMM will shift between left, center, or right to identify the type  
and also to prevent the wrong type from being inserted into the DIMM slot on the  
motherboard. You must tell your retailer the correct DIMM type before purchasing.  
This motherboard supports four clock signals per DIMM.

3.6 Central Processing Unit (CPU)  
The motherboard provides a ZIF Socket 370. The CPU that came with the mother-  
board 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.  
WARNING! Be sure that there is sufficient air circulation across the processors  
heatsink by regularly checking that your CPU fan is working. Without sufficient  
circulation, the processor could overheat and damage both the processor and the  
motherboard. You may install an auxiliary fan, if necessary.  
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 angle. Insert the CPU with the correct orientation as shown.  
The notched corner should point towards the end of the lever. Because the CPU has  
a corner pin for two of the four corners, the CPU will only fit in the orientation as  
shown. The picture is for reference only; you should have a CPU fan that covers the  
face of the CPU. With the added weight of the CPU fan, no force is required to  
insert the CPU. Once completely inserted, close the sockets lever while holding  
down the CPU.After the CPU is , install an Intel recommended fan heatsink. Locate  
the CPU fan connector (see 3.1 Motherboard Layout or 3.8 Connectors) and con-  
nect the CPU fan cable to it.  
NOTE: Do not forget to set the correct Bus Frequency and Multiple (frequency  
multiple setting is available only on unlocked processors) for your Socket 370 pro-  
cessor or else boot-up may not be possible. Socket 370 processors provide internal  
thermal sensing so that a socket mounted thermal resistor is not needed.  
CAUTION! Be careful not to scrape the motherboard when mounting a clamp-  
style processor fan or else damage may occur to the motherboard.

3.7 Expansion Cards  
WARNING! 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.  
3.7.1 Expansion Card Installation Procedure  
1. Read the documentation for your expansion card and make any necessary hard-  
ware or software settings for your expansion card, such as jumpers.  
2. Remove your computer systems cover and the bracket plate on the slot you  
intend to use. Keep the bracket for possible future use.  
3. Carefully align the cards connectors and press firmly.  
4. Secure the card on the slot with the screw you removed above.  
5. Replace the computer systems cover.  
6. Set up the BIOS if necessary  
(such as IRQ xx Used By ISA: Yes in 4.4.3 PCI Configuration)  
7. Install the necessary software drivers for your expansion card.

3.7.2 Assigning IRQs for Expansion Cards  
Some expansion cards need an IRQ to operate. Generally, an IRQ must be exclu-  
sively assigned to one use. In a standard design, there are 16 IRQs available but  
most of them are already in use, leaving 6 IRQs free for expansion cards. If your  
motherboard has PCI audio onboard, an additional IRQ will be used. If your moth-  
erboard also has MIDI enabled, another IRQ will be used, leaving 4 IRQs free.  
IMPORTANT: If using PCI cards on shared slots, make sure that the drivers sup-  
port Share IRQor that the cards do not need IRQ assignments. Conflicts will arise  
between the two PCI groups that will make the system unstable or cards inoperable.  
The following table lists the default IRQ assignments for standard PC devices. Use  
this table when configuring your system and for resolving IRQ conflicts.

3. HARDWARE SETUP  
Both ISA and PCI expansion cards may require IRQs. System IRQs are available to  
cards installed in the ISA expansion bus first, then any remaining IRQs are available  
to PCI cards. Currently, there are two types of ISA cards.  
The original ISA expansion card design, now referred to as legacy ISA cards, re-  
quires that you configure the cards jumpers manually and then install it in any  
available slot on the ISA bus. To see a map of your used and free IRQs in Windows  
98, the Control Panel icon in My Computer, contains a System icon, which gives  
you a Device Manager tab. Double-clicking on a specific hardware device gives  
you the Resources tab which shows the Interrupt number and address. Double-click  
Computer to see all the interrupts and addresses for your system. Make sure that no  
two devices use the same IRQ or your computer will experience problems when  
those two devices are in use at the same time.  
To simplify this process, this motherboard complies 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 con-  
figuration of the BIOS setup utility can be used to indicate which IRQs are being  
used by legacy cards. For older legacy cards that do 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 as-  
signs an IRQ to PCI cards that require an IRQ. To install a PCI card, you need to set  
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 (see 4.4.3 PCI Configuration. Choose Yes in IRQ xx Used By  
ISA and DMA x Used By ISA for those IRQs and DMAs you want to reserve).

3.8 Connectors  
WARNING! Some pins are used for connectors or power sources. These are  
clearly distinguished from jumpers in the Motherboard Layout. Placing jumper  
caps over these connector pins will cause damage to your motherboard.  
IMPORTANT: Ribbon cables should always be connected with the red stripe to  
Pin 1 on the connectors. Pin 1 is usually on the side closest to the power connec-  
tor on hard drives and CD-ROM drives, but may be on the opposite side on  
floppy disk drives. Check the connectors before installation because there may  
be exceptions. IDE ribbon cables must be less than 46 cm (18 in.), with the  
second drive connector no more than 15 cm (6 in.) from the first connector.  
1) PS/2 Mouse Connector (Green 6-pin PS2KBMS)  
The system will direct IRQ12 to the PS/2 mouse if one is detected. If one is not  
detected, expansion cards can use IRQ12. See PS/2 Mouse Function Control  
in 4.4 Advanced Menu.

4. BIOS SETUP  
4.1 Managing and Updating Your BIOS  
4.1.1 Upon First Use of the Computer System  
It is recommended that you save a copy of the original motherboard BIOS  
along with a Flash Memory Writer utility (AFLASH.EXE) to a bootable  
floppy disk in case you need to reinstall the BIOS later. AFLASH.EXE is a  
Flash Memory Writer utility that updates the BIOS by uploading a new  
BIOS file to the programmable flash ROM on the motherboard. This file  
works only in DOS mode. To determine the BIOS version of your mother-  
board, 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.  
1. Type FORMAT A:/S at the DOS prompt to create a bootable system  
floppy disk. DO NOT copy AUTOEXEC.BAT & CONFIG.SYS to the  
disk.  
2. Type COPYD:\AFLASH\AFLASH.EXEA:\ (assuming D is your CD-  
ROM drive) to copy AFLASH.EXE to the just created boot disk.  
NOTE: AFLASH works only in DOS mode. It will not work with DOS  
prompt in Windows and will not work with certain memory drivers that  
may be loaded when you boot from your hard drive. It is recommended  
that you reboot using a floppy.  
3. Reboot your computer from the floppy disk. NOTE: BIOS setup must  
specify Floppyas the first item in the boot sequence.  
4. In DOS mode, type A:\AFLASH <Enter> to run AFLASH.  
IMPORTANT! If unknownis displayed after Flash Memory:, the memory  
chip is either not programmable or is not supported by theACPI BIOS and there-  
fore, cannot be programmed by the Flash Memory Writer utility.

6. Type a filename and the path, for example, A:\XXX-XX.XXX and then  
press <Enter>.  
4.1.2 Updating BIOS Procedures (only when necessary)  
1. Download an updated ASUS BIOS file from the Internet (WWW or  
FTP) (see ASUS 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>. The Update BIOS  
Including Boot Block and ESCD screen appears.  
5. Type the filename of your new BIOS and the path, for example, A:\XXX-  
XX.XXX, and then press <Enter>.  
NOTE: To cancel this operation, press <Enter>.

6. When prompted to confirm the BIOS update, press Y to start the update.  
7. The utility starts to program the new BIOS information into the flash  
ROM. The boot block will be updated automatically only when neces-  
sary. This will minimize the chance of a failed updating. When the pro-  
gramming is finished, Flashed Successfully will be displayed.  
8. Follow the onscreen instructions to continue.  
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, up-  
date 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 servicing.

4. BIOS SETUP  
4.2 BIOS Setup Program  
This motherboard supports a programmable EEPROM that can be updated using  
the provided utility as described in 4.1 Managing and Updating Your BIOS.  
The utility is used if you are installing a motherboard, reconfiguring your system,  
or prompted to Run Setup. This section describes how to configure your system  
using this utility.  
Even if you are not prompted to use the Setup program, at some time in the future  
you may want to change the configuration of your computer. For example, you  
may want to enable the Security Password Feature or make changes to the power  
management settings. It will then be necessary to reconfigure your system using  
the BIOS Setup program so that the computer can recognize these changes and  
record them in the CMOS RAM of the EEPROM.  
The EEPROM on the motherboard stores the Setup utility. When you start up the  
computer, the system provides you with the opportunity to run this program. This  
appears during the Power-On Self Test (POST). Press <Delete> to call up the Setup  
utility. If you are a little bit late in pressing the mentioned key, POST will continue  
with its test routines, thus preventing you from calling up Setup. If you still need to  
call Setup, restart the system by pressing <Ctrl> + <Alt> + <Delete>, or by press-  
ing the Reset button on the system chassis. You can also restart by turning the  
system off and then back on again. But do so only if the first two methods fail.  
The Setup program has been designed to make it as easy to use as possible. It is a  
menu-driven program, which means you can scroll through the various sub-menus  
and make your selections among the predetermined choices.  
To access the BIOS Setup program, press the <Delete> key after  
the computer has run through its POST.  
NOTE: Because the BIOS software is constantly being updated, the following  
BIOS screens and descriptions are for reference purposes only and may not re-  
flect your BIOS screens exactly.

CPU Speed [Manual]  
When the motherboard is set to JumperFree mode (see 3.4 Motherboard  
Settings), this field allows you to select the internal speed of your CPU.  
Available options include multiples of 66 and 100. Select [Manual] if you  
want to make changes to the subsequent 2 fields. Note that selecting a fre-  
quency higher than the CPU manufacturer recommends may cause the sys-  
tem to hang or crash. See System Hangup later in this section.  
CPU Core:Bus Freq. Multiple (when CPU Speed is set to [Manual])  
This field is for unlocked processors only. This sets the frequency multiple  
between the CPUs internal frequency and external frequency. This must be  
set in conjunction with CPU Bus/PCI Frequency to match the speed of  
your CPU. Configuration options vary according to the external frequency  
of your CPU.  
CPU Bus/PCI Freq. (MHz)  
(when CPU Speed is set to [Manual])  
This feature tells the clock generator what frequencies to  
send to the local bus and PCI devices onboard. The bus fre-  
quency (external frequency) multiplied by the bus multiple  
equals the CPUs internal frequency (the CPU speed).

7.2 ASUS CIDB Intrusion Detection Module  
The optional ASUS CIDB is a module for providing audible intrusion alarm and  
logging for ASUS motherboards equipped with the chassis connector. The module  
detects a chassis intrusion by either light striking its photo sensor or by the closing  
or opening of a chassis-mounted momentary toggle switch. An intrusion memory  
function allows detection and clearing the intrusion notification by the BIOS pro-  
gram on the next bootup.

7.2.1 Using the ASUS CIDB  
1. You must have an ASUS motherboard with: (1) a chassis connector and (2) a  
System Management Bus (SMB) connector.  
2. Connect the CIDB directly to the chassis connector or use the provided exten-  
sion cable and mount the CIDB to the chassis using a double-sided foam adhe-  
sive tape or with screws and spacer posts.  
CAUTION! The CIDBs component pins and metallic points must not come in  
contact with another metallic surface or else shorting will occur!  
3. Use the SMBIN connector and the provided SMB cable to connect the CIDB to  
the SMB connector on the motherboard. If another SMB device is already used  
on the motherboard, you may unplug it and connect it to the SMBOUT connec-  
tor on the CIDB.  
4. Check the hardware settings:  
PHOTO jumper should be enabled to use the photo sensor.  
MS1 and/or MS2 connectors should be connected to momentary toggle  
switches mounted on the chassis to use the switch close or switch open  
method for triggering an intrusion event.

7. APPENDIX  
5. To stop the alarm from sounding, use the BIOS setup or momentarily place a  
jumper on (or short manually) the CLR jumper. Note that the jumper must be  
removed for the CIDB to work normally again.  
6. If you have an updated BIOS with intrusion support, booting the computer after  
an intrusion may require a password if configured through BIOS.

7.2.3 ASUS CIDB Additional Considerations  
1. If there is no power to the motherboard (i.e. removing the power cord or turning  
the power supplys switch off), the alarm will not sound but the CIDB will still  
memorize an intrusion event which BIOS will detect on the next bootup.  
2. Any chassis intrusion detection components on the motherboard will not work if  
the CIDB is used.  
3. The P2B-LS motherboard must use an external battery pack on the EXTBATT  
connector or else neither the alarm or intrusion memory functions will work.

7.3 Glossary  
1394  
1394 is the IEEE designation for the high performance serial bus at 12.5, 25 or  
50MBytes/sec speeds. This serial bus defines both a back plane physical layer and a  
point-to-point cable-connected virtual bus. The primary application of the cable ver-  
sion is the integration of I/O connectivity at the back panel of personal computers  
using a low-cost, scalable, high-speed serial interface. The 1394 standard also pro-  
vides new services such as live connect/disconnect capability for external devices  
including disk drives, printers and hand-held peripherals such as scanners and cam-  
eras. This is a new standard to complement the slower USB interface and to compete  
with the more expensive SCSI interface.  
AC97 (Audio Codec '97)  
AC '97 is the next step in enabling PCs with audio quality comparable to consumer  
electronics devices. The specification defines new cost-effective options to help in-  
tegrate the components necessary to support next-generation auto-intensive PC ap-  
plications such as DVD, 3-D multiplayer gaming and interactive music. The speci-  
fication also defines new extensions supporting modem and docking to help both  
desktop and mobile manufacturers adopt these new technologies more quickly and  
cost-effectively. This specification uses software emulation to compete with the PCI  
SoundBlaster specification.  
ACPI (Advanced Configuration and Power Interface)  
TheACPI specification defines a cross-platform interface designed to support many  
operating systems. ACPI defines a flexible and abstract hardware interface that pro-  
vides a standard way to integrate power management features throughout a PC sys-  
tem, including hardware, operating system and application software. This enables  
the system to automatically turn ON and OFF peripherals such as CD-ROMs, net-  
work cards, hard disk drives, and printers, as well as consumer devices connected to  
the PC such as VCRs, TVs, phones, and stereos. With this technology, peripherals  
will also be able to activate the PC. For example, inserting a tape into a VCR can  
turn on the PC, which could then activate a large-screen TV and high-fidelity sound  
system.  
AGP (Accelerated Graphics Port)  
An interface specification that enables high-performance 3D graphics on mainstream  
PCs. AGP was designed to offer the necessary bandwidth and latency to perform  
texture mapping directly from system memory.

BIOS (Basic Input/Output System)  
BIOS is a set of routines that affect how the computer transfers data between com-  
puter components, such as memory, disks, and the display adapter. The BIOS in-  
structions are built into the computers read-only memory. BIOS parameters can be  
configured by the user through the BIOS Setup program. The BIOS can be updated  
using the provided utility to copy a new BIOS file into the EEPROM.  
Bit (Binary Digit)  
Represents the smallest unit of data used by the computer. A bit can have one of two  
values: 0 or 1.

7. APPENDIX  
Boot  
Boot means to start the computer operating system by loading it into system memory.  
When the manual instructs you to bootyour system (or computer), it means to  
turn ON your computer. Rebootmeans to restart your computer. When using Win-  
dows 95 or later, selecting Restartfrom Start | Shut Down...will reboot your  
computer.  
Bus Master IDE  
PIO (Programmable I/O) IDE requires that the CPU be involved in IDE access and  
waiting for mechanical events. Bus master IDE transfers data to/from the memory  
without interrupting the CPU. Bus master IDE driver and bus master IDE hard disk  
drives are required to support bus master IDE mode.  
Byte (Binary Term)  
One byte is a group of eight contiguous bits. A byte is used to represent a single  
alphanumeric character, punctuation mark, or other symbol.  
COM Port  
COM is a logical device name used by to designate the computer serial ports. Point-  
ing devices, modems, and infrared modules can be connected to COM ports. Each  
COM port is configured to use a different IRQ and address assignment.  
Concurrent PCI  
Concurrent PCI maximizes system performance with simultaneous CPU, PCI and  
ISA bus activities. It includes multi-transaction timing, enhanced write performance,  
a passive release mechanism and support for PCI 2.1 compliant delayed transac-  
tions. Concurrent PCI provides increased bandwidth, reduced system latencies, im-  
proves video and audio performance, and improves processing of host based appli-  
cations.  
CPU (Central Processing Unit)  
The CPU, sometimes called Processor,actually functions as the brainof the  
computer. It interprets and executes program commands and processes data stored  
in memory. Currently, there are socket 370 (for Pentium III FC-PGA and Celeron-  
PPGA), socket 7 (for Pentium, AMD, Cyrix, IBM), slot 1 (for Pentium II and III),  
slot 2 (for Xeon), and slot A (for AMD) processors.  
Device Driver  
A device driver is a special set of instructions that allows the computers operating  
system to communicate with devices such as VGA, audio, printer, or modem.  
DOS (Disk Operating System)  
DOS is the foundation on which all other programs and software applications oper-  
ate, including Windows. DOS is responsible for allocating system resources such as  
memory, CPU time, disk space, and access to peripheral devices. For this reason,  
DOS constitutes the basic interface between you and your computer.  
DRAM (Dynamic Random Access Memory)  
There are several different types of DRAM such as, EDO DRAM (Extended Data  
Output DRAM), SDRAM (Synchronous DRAM), and RDRAM (Rambus DRAM).  
Flash ROM  
The flash ROM is designed to be a resident program and can be updated by a spe-  
cific programming method. Normally, the flash ROM is used for system BIOS which  
initiates hardware devices and sets up necessary parameters for the OS. Since the  
contents of flash ROM can be modified, users are able to update the BIOS by them-  
selves.  
IDE (Integrated Drive Electronics)  
IDE devices integrate the drive control circuitry directly on the drive itself, elimi-  
nating the need for a separate adapter card (in the case for SCSI devices). UltraDMA/  
100 IDE devices can achieve up to 100MB/Sec transfer.

7. APPENDIX  
LPT Port (Line Printer Port)  
Logical device name reserved by DOS for the computer parallel ports. Each LPT  
port is configured to use a different IRQ and address assignment.  
MMX  
A set of 57 new instructions based on a technique called Single Instruction, Multiple  
Data (SIMD), which is built into the new Intel Pentium PP/MT (P55C) and Pentium  
II (Klamath) CPU as well as other x86-compatible microprocessors. The MMX in-  
structions are designed to accelerate multimedia and communications applications,  
such as 3D video, 3D sound, video conference.  
OnNow  
The OnNow design initiative is a comprehensive, system-wide approach to system  
and device power control. OnNow is a term for PC that is always ON but appears  
OFF and responds immediately to user or other requests. The OnNow design initia-  
tive involves changes that will occur in the Microsoft Windows operating system,  
device drivers, hardware, and applications, and also relies on the changes defined in  
the Advanced Configuration and Power Interface (ACPI) specification.  
PC100  
SDRAM is Intel's goal is to ensure that memory subsystems continue to support  
evolving platform requirements and to assure that memory does not become a bottle-  
neck to system performance. It is especially important to ensure that the PC memory  
roadmap evolves together with the performance roadmaps for the processors, I/O  
and graphics.  
PCI Bus (Peripheral Component Interconnect Local Bus)  
PCI bus is a specification that defines a 32-bit data bus interface. PCI is a standard  
widely used by expansion card manufacturers.  
PCI Bus Master  
The PCI Bus Master can perform data transfer without local CPU help and further-  
more, the CPU can be treated as one of the Bus Masters. PCI 2.1 supports concur-  
rent PCI operation to allow the local CPU and bus master to work simultaneously.  
Plug and Play BIOS  
The ISA bus architecture requires the allocation of memory and I/O address, DMA  
channels and interrupt levels among multiple ISA cards. However, configuration of  
ISA cards is typically done with jumpers that change the decode maps for memory  
and I/O space and steer the DMA and interrupt signals to different pins on the bus.  
Further, system configuration files may need to be updated to reflect these changes.  
Users typically resolve sharing conflicts by referring to documentation provided by  
each manufacturer. For the average user, this configuration process can be unreli-  
able and frustrating. Plug and play (PnP) BIOS eliminates the ISA add-on card hard-  
ware conflict problem. The PnP BIOS uses a memory block to define and remember  
each card's configuration, which allows the user to change the card's IRQs and DMA  
in BIOS either automatically or manually.  
POST (Power On Self Test)  
When you turn ON the computer, it will first run through the POST, a series of  
software-controlled diagnostic tests. The POST checks system memory, the mother-  
board circuitry, the display, the keyboard, the diskette drive, and other I/O devices.  
PS/2 Port  
PS/2 ports are based on IBM Micro Channel Architecture. This type of architecture  
transfers data through a 16-bit or 32-bit bus. A PS/2 mouse and/or keyboard may be  
used on ATX motherboards.  
RDRAM (Rambus DRAM)  
Developed by Rambus, Inc., this type of memory can deliver up to 1.6GB of data  
per second. RDRAM is the first interface standard that can be directly implemented  
on high performance VLSI components such as, CMOS DRAMs, memory control-  
lers, and graphics/video ICs.

7. APPENDIX  
ROM (Read Only Memory)  
ROM is nonvolatile memory used to store permanent programs (called firmware)  
used in certain computer components. Flash ROM (or EEPROM) can be repro-  
grammed with new programs (or BIOS).  
SCSI (Small Computer System Interface)  
High speed multi-threaded I/O interface defined by the X3T9.2 committee of the  
American National Standards Institute (ANSI) for connecting many peripheral de-  
vices. The standard started from 10MBytes/sec to 160MBytes/sec available today.  
SDRAM (Synchronous DRAM)  
The SDRAM features a fully synchronous operation referenced to a positive edge  
clock whereby all operations are synchronized at a clock input which enables the  
coexistence of high performance and a simple user interface. SDRAM takes memory  
access away from the CPU's control; internal registers in the chips accept the re-  
quest, and let the CPU do something else while the data requested is assembled for  
the next time the CPU talks to the memory. As they work on their own clock cycle,  
the rest of the system can be clocked faster. There is a version optimized for video  
cards, and main memory for motherboards.  
SPD for SDRAM module  
Serial Presence Detect (SPD) is most like an ID detect for SDRAM module, it using  
a EEPROM component on DIMM module for storing module configuration infor-  
mation inside. The Serial Presence Detect function is implemented using a 2048 bit  
EEPROM component. This nonvolatile storage device contains data programmed  
by the DIMM manufacturer that identifies the module type and various SDRAM  
organization and timing parameters.  
SSE (Streaming SIMD Extensions)  
A set of new instructions added to existing architectures that enables a better visual  
experience with an accelerated 3D geometry pipeline and support for new applica-  
tions, such as real-time video encoding and speech recognition.  
System Disk  
A system disk contains the core file of an operating system and is used to boot up the  
operating system.  
UltraDMA  
Ultra DMA/33 is a "synchronous DMA" protocol designed by Intel. This function is  
included into Intel's PIIX4 chipset. The traditional IDE transfer only uses one edge  
of the data stroke as the data transfer. Ultra DMA/33 uses both edges of data strobe  
when the data is transferred. Hence, the data transfer rate is double of the PIO mode  
4 or DMA mode 2 (16.6MB/s x2 = 33MB/s) on ATA-2 devices.  
Ultra ATA/66, also known as Ultra DMA/66, is an extension of current Ultra ATA/  
33 interface. This new high-speed interface has doubled the Ultra ATA/33 burst data  
transfer rate to 66.6 Mbytes/sec and maximized disk performance under current PCI  
local bus environment  
USB (Universal Serial Bus)  
A 4-pin serial cable bus that allows up to 127 plug and play computer peripherals  
such as keyboard, mouse, joystick, scanner, printer, modem, and monitor to share a  
bandwidth through a host scheduled token based protocol. This allows attaching or  
detaching while the host and other peripherals are in operation. Supports synchro-  
nous and asynchronous transfer types over the same set of wires up to 12Mbit/sec.  
USB 2.0 provides twice the transfer rate compared to USB 1.0 and competes with  
the 1394 standard.  
Wake-On-LAN  
Computer will automatically wake-up upon receiving a wake-up packet through a  
Network interface when it is under power soft-off, suspend or sleep mode.
