UltraPerformance! Onboard IDE Bus Master controller with two connectors
that support four IDE devices in two channels. Supports UltraDMA/66, UltraDMA/
33 (IDE DMA Mode 2), PIO Modes 3 & 4, and supports Enhanced IDE devices,
such as Tape Backup, CD-ROM, CD-R/RW, and LS-120 drives.
Dual Speeds! CPU frequency can operate at either 66MHz or 100MHz while
system memory operates at either 100MHz or 66MHz. (100MHz CPU with 66MHz
SDRAM setting not supported) This asynchronous design can optimize the VGA
performance under shared memory configuration. Of course 100MHz/100MHz
synchronous host/DRAM clock is recommended for maximum performance.
Double or Quadruple the IDE Transfer Speed! IDE transfers using UltraDMA/
33 Bus Master IDE can handle rates up to 33MB/s and up to 66MB/s using
UltraDMA/66 technology. The best of all is that these new technology is compatible with existing ATA-2 IDE specifications so there is no need to upgrade
current IDE devices or cables.
Concurrent PCI! Concurrent PCI allows multiple PCI transfers from PCI master buses to memory to CPU.
SDRAM Optimized Performance! ASUS smart series motherboards support the
new generation memory, Synchronous Dynamic Random Access Memory (SDRAM),
which increases the data transfer rate to 800MB/s max using PC100 SDRAM.
ACPI Ready! ACPI (Advanced Configuration and Power Interface) is also implemented on all ASUS smart series motherboards. ACPI provides more Energy
Saving Features for future operating systems (OS) supporting 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.
Suspend and Go! Suspend-to-RAM (STR) provides maximum power savings
as an alternative to leaving the computer ON and QuickStart™ so that you do
not fall asleep waiting for system bootup. (STR requires OS support and does
not support ISA cards; ISA cards may fail to work coming out of STR mode.)
New Compliancy! Both the BIOS and hardware levels of the motherboard meet
PC’99 compliancy (on model without ISA). The new PC’99 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 procedures
for Windows 95/98/NT. Color-coded connectors and descriptive icons make identification easy as required by PC’99.
Highest Audio Quality! AC’97 DAC/ADC built into the audio CODEC reduces
noise to improve audio quality and performance for a SNR (signal to noise ratio) of
+90dB. These features greatly improve voice synthesis and recognition.
Extreme Graphics! The integrated motion compensation allows for smooth
MPEG1 or MPEG2 video playback. Fast 3D graphics engine allows for an exciting gameplay experience.

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 the fans are set for its normal RPM range and alarm thresholds.
Temperature Monitoring and Alert! To prevent system overheat and system
damage, this motherboard supports Socket 370 processor thermal sensing and
auto-protection.
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 Resources Alert! (Requires the future release of LDCM v6.0) Today’s
operating systems such as Windows 98, Windows NT, and OS/2, require much
more memory and hard drive space to present enormous 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.
Dual Function Power Button! Through BIOS, the power button can be defined
as the “Stand by” (a.k.a. Suspend or Sleep) button or as the Soft-Off (see ATX
Power Switch for more information) button. Regardless of the setting, pushing
the power button for more than 4 seconds will enter the Soft-Off mode.
Remote Ring On (requires modem)! This allows a computer to be turned on
remotely through an internal or external modem. With this benefit on-hand, users
can access any information from their computers from anywhere in the world!
Message LED (requires ACPI OS support)! Chassis LEDs now act as information providers. Through the way a particular LED illuminates, the user can
determine the stage the computer is in. A simple glimpse provides useful information to the user.
Peripheral Power Up! Keyboard or Mouse power up can be enabled or disabled through BIOS setup to allow the computer to be powered ON using your
keyboard or mouse click.

3.3 Hardware Setup Procedure
Before using your computer, you must complete the following steps:
• Check Motherboard Settings
• Install Memory Modules
• Install the Central Processing Unit (CPU)
• Install Expansion Cards
• Connect Ribbon Cables, Panel Wires, and Power Supply
3.4 Motherboard Settings
This section explains in detail how to change your motherboard’s function settings
through the use of switches and/or jumpers.
3. H/W SETUP
Motherboard Settings
WARNING! Computer motherboards and expansion 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.
Motherboard Feature Settings (DSW)
Besides jumper settings, some of the motherboard’s onboard functions are adjusted
through the DIP switches. The white block represents the switch’s position. The

Usually socket 370 processors have locked frequency multiples. In this case,
there is no way to exceed the specified multiple whether through motherboard
settings or BIOS setup. With unlocked socket 370 processors, exceeding the

8) CPU External Frequency Setting (DSW)
This option tells the clock generator what frequency to send to the CPU, DRAM,
and the PCI bus. This allows the selection of the CPU’s External frequency. The
CPU External Frequency multiplied by the Frequency Multiple equals the CPU’s
Internal frequency (the advertised CPU speed). NOTE: You may set the memory
speed independently from the CPU External Frequency. Depending on your
memory type PC66 (66MHz) or PC100 (100MHz), select the appropriate
“SDRAM” speed along with the appropriate “CPU” speed.
IMPORTANT: Only 66MHz CPU and 100MHz SDRAM should be used on
this motherboard with current 66MHz Socket 370 processors. Other settings are
for experienced users only. When JumperFree mode is enabled, use BIOS setup
in place of these switches (see CPU Speed in 4.4 Advanced Menu). Only selected switches are illustrated, see the next page for a complete frequency listing.
NOTE: In JumperFree mode, all dip switches (DSW) must be set to OFF.

processor does not have a locked Frequency Multiple, you must use CPU
Core:Bus Freq. Multiple in 4.4 Advanced Menu of the BIOS setup to set the
Frequency Multiple. If the Frequency Multiple is locked, setting the Frequency
Multiple in BIOS setup will have no effect.
WARNING! CPU frequencies above 66MHz exceed the specifications for current Celeron processors and are not guaranteed to be stable. Premature wearing of
the processor may result when overclocking. Be sure that the DIMM you use can
handle the specified SDRAM MHz or else bootup will not be possible.

greatly improve the onboard graphics’ performance.
3.5.1 General DIMM Notes
•
•
•
•
•
24
When this motherboard operates at 100MHz, PC100-compliant modules must
be used because of the strict timing issues involved under this speed. If your
DIMMs are not PC100-compliant, set the SDRAM bus frequency to 66MHz
RAM but onboard graphics performance and PCI expansion cards will suffer
tremendously.
ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the
memory of choice for best performance vs. stability.
SDRAM chips are generally thinner with higher pin density than EDO (Extended 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.

3.5.2 DIMM Memory Installation
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. DIMM modules are longer and have different pin contact on each side and therefore have a

3. HARDWARE SETUP
3.6 Central Processing Unit (CPU)
The motherboard provides a ZIF Socket 370. 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.
WARNING! Be sure that there is sufficient air circulation across the processor’s
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.
3. H/W SETUP
CPU
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 socket’s lever while holding
down the CPU.
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 processor 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 clampstyle processor fan or else damage may occur to the motherboard.

3.7 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.
3.7.1 Expansion Card Installation Procedure
3. H/W SETUP
Expansion Cards
1. Read the documentation for your expansion card and make any necessary hardware or software settings for your expansion card, such as jumpers or switches.
2. Remove your computer system’s cover and the bracket plate with screw on the
slot you intend to use. Keep the bracket for possible future use.
3. Carefully align the card’s connectors and press firmly.
4. Secure the card on the slot with the screw you removed above.
5. Replace the computer system’s cover.
6. Set up the BIOS if necessary
(such as IRQ xx Used By ISA: Yes in PNP AND PCI SETUP)
7. Install the necessary software drivers for your expansion card.
3.7.2 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 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 extra IRQ will be used. If your motherboard also has Midi enabled, an extra 1 IRQs will be used, leaving 4 IRQs free.
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,
requires that you configure the card’s 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. 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 whenever a PNP-compliant card is added to the system. For PNP cards, IRQs are assigned automatically from those available.
ASUS MEW User’s Manual
27
3. HARDWARE SETUP
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.
3.7.3 Assigning DMA Channels for ISA Cards
3. H/W SETUP
Expansion Cards
Some ISA cards, 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. To select a DMA channel, see PCI/
PNP ISA DMA Resource Exclusion in 4.4.3 PCI Configuration. NOTE: The onboard audio by default uses DMA1.
IMPORTANT: To avoid conflicts, reserve the necessary IRQs and DMAs for
legacy ISA cards (see PCI/PNP USA IRQ Resource Exclusion in 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).
3.7.4 Audio Modem Riser (AMR) Slot
This connector supports a specially designed audio and/or modem card called an AMR.
Main processing is done through software and controlled by the motherboard’s Intel
Controller Hub (ICH). This provides an upgradeable audio and/or modem solution at
an incredibly low cost. There are two types of AMR, one defined as primary and
another defined as secondary. This motherboard uses the primary channel so that a
secondary AMR can coexist without the need to disable the onboard CODEC. The
motherboard’s onboard CODEC must be disabled when using a primary AMR.
NOTE: An AMR is not included with this motherboard.

3.8 External 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 connector 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. Look on IDE ribbon cable must be less than 46 cm (18 in.), with
the second drive connector no more than 15 cm (6 in.) from the first connector.

Connectors
NOTE: Onboard Fast-Ethernet is optional at the time of purchase. The illustrations
below are that of the model without the onboard Fast-Ethernet.
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.
PS/2 Mouse (6-pin Female)
2) PS/2 Keyboard Connector (Purple 6-pin PS2KBMS)
This connection is for a standard keyboard using an PS/2 plug (mini DIN). This

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 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.
4. BIOS SETUP
Updating BIOS
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 COPY D:\AFLASH\AFLASH.EXE A:\ (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 it recommended that you reboot using a floppy.
3. Reboot your computer from the floppy disk. NOTE: BIOS setup must specify
“Floppy” as the first item in the boot sequence.
4. In DOS mode, type A:\AFLASH <Enter> to run AFLASH.
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.

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, 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 servicing.

4.2 BIOS Setup Program
This motherboard supports a programmable EEPROM that can be updated using
the provided utility as described in 4.1 Flash Memory Writer Utility.
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.
4. BIOS SETUP
Program Information
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 pressing 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.

Operating Systems
Although ASUS motherboards passed testing on several operating systems, the operating system shown in these sections will be that of Microsoft’s Windows 98. You
should always use the latest operating system and updates when using new hardware to ensure full compliancy. For Windows 95, you must use OSR 2.0 or later. For
Windows NT 4.0, you must use Service Pack 3.0 or later.
Windows 98
When Windows 98 is installed for the first time. Subsequent restarts will result in
the plug and play initializing the “Add New Hardware Wizard” and may attempt to
install a driver from its system registry. When prompted to restart, select No and
then follow the normal setup procedures later in this section.
IMPORTANT: Selecting No for the initial restart prompt is a necessary step
because Windows may load an older display driver that is incompatible with the
onboard VGA chip. Always use the driver available on the ASUS Support CD or
an applicable driver update from your ASUS vendor or from the ASUS web site.

DMI Utility
6.5 Desktop Management Interface (DMI)
Introducing the ASUS DMI Configuration Utility
This motherboard supports DMI within the BIOS level and provides a DMI Configuration Utility to maintain the Management Information Format Database (MIFD).
DMI is able to auto-detect and record information pertinent to a computer’s system
such as the CPU type, CPU speed, and internal/external frequencies, and memory
size. The onboard BIOS will detect as many system information as possible and
store those collected information in a 4KB block in the motherboard’s Flash EPROM
and allow the DMI to retrieve data from this database. Unlike other BIOS software,
the BIOS on this motherboard uses the same technology implemented for Plug and
Play to allow dynamic real-time updating of DMI information versus creating a new
BIOS image file and requiring the user to update the whole BIOS. This DMI Configuration Utility also allows the system integrator or end user to add additional
information into the MIFD such as serial numbers, housing configurations, and vendor information. Those information not detected by the motherboard BIOS and has
to be manually entered through the DMI Configuration Utility and updated into the
MIFD. This DMI Configuration Utility provides the same reliability as PnP updating and will prevent the refreshing failures associated with updating the entire BIOS.
Starting the ASUS DMI Configuration Utility
The DMI Configuration Utility (DMICFG2.EXE) must be used in real mode in
order for the program to run, the base memory must be at least 180K. Memory
managers like HIMEM.SYS (required by windows) must not be installed. You can
boot up from a system diskette without AUTOEXEC.BAT and CONFIG.SYS files,
“REM” HIMEM.SYS in the CONFIG.SYS, or press <Shift>+<F5> during bootup
to bypass your AUTOEXEC.BAT and CONFIG.SYS files.
1. In Windows, copy DMICFG2.EXE to your hard disk drive.
2. Restart your computer and press <Shift>+<F5> during bootup to enter safe mode
command prompt.
3. Go to the directory containing DMICFG2.EXE.
4. Type DMICFG2 and press <Enter> to run.

AUTOEXEC.BAT
AUTOEXEC.BAT is a special-purpose file that is automatically executed by DOS
whenever the computer is turned ON or restarted. This file contains important commands that help configure the system to work with certain software and devices.
Windows 95 and later has its own startup files and may not use or may ignore parts
of the AUTOEXEC.BAT file.
BIOS (Basic Input/Output System)
BIOS is a set of routines that affect how the computer transfers data between computer components, such as memory, disks, and the display adapter. The BIOS instructions are built into the computer’s 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.
Boot
Boot means to start the computer operating system by loading it into system memory.
When the manual instructs you to “boot” your system (or computer), it means to
turn ON your computer. “Reboot” means to restart your computer. When using Windows 95 or later, selecting “Restart” from “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.

CPU (Central Processing Unit)
The CPU, sometimes called “Processor,” actually functions as the “brain” of the
computer. It interprets and executes program commands and processes data stored
in memory. Currently, there are socket 370 (for Pentium Celeron-PPGA), socket 7
(for Pentium, AMD, Cyrix, IBM), slot 1 (for Pentium II and III), and slot 2 (for
Xeon) processors.
Device Driver
A device driver is a special set of instructions that allows the computer’s operating system to communicate with devices such as VGA, audio, ethernet, printer, or modem.
DOS (Disk Operating System)
DOS is the foundation on which all other programs and software applications operate, 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.
Hardware
Hardware is a general term referring to the physical components of a computer system, including peripherals such as printers, modems, and pointing devices.
IDE (Integrated Drive Electronics)
IDE devices integrate the drive control circuitry directly on the drive itself, eliminating the need for a separate adapter card (in the case for SCSI devices). UltraDMA/
33 IDE devices can achieve up to 33MB/Sec transfer.
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 instructions are designed to accelerate multimedia and communications applications,
such as 3D video, 3D sound, video conference.

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.
RAID (Redundant Array of Independent Disks)
RAID can be set up to provide mirroring (for fault tolerance), parity (for data guarding), or striping (for data distribution over several drives for increased performance).
A RAID card is required to setup a RAID system.
RAM (Random Access Memory)
There are several different types of RAM such as DRAM (Dynamic RAM), EDO
DRAM (Extended Data Output DRAM), SDRAM (Synchronous DRAM).
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 reprogrammed with new programs (or BIOS).
SCSI (Small Computer System Interface)
High speed parallel interface defined by the X3T9.2 committee of the American
National Standards Institute (ANSI) for connecting many peripheral devices.
System Disk
A system disk contains the core file of an operating system and is used to boot up the
operating system.
UltraDMA/33
UltraDMA/33 is a new specification to improve IDE transfer rates. Unlike traditional PIO mode, which only uses the rising edge of IDE command signal to transfer
data, UltraDMA/33 uses both rising edge and falling edge. Hence, the data transfer
rate is double of the PIO mode 4 or DMA mode 2. (16.6MB/s x2 = 33MB/s).
