The Motherboard
Cache Memory
The processor comes with 16 KB of L1 cache, and is
available with 256 or 512 KB of internal L2 cache.
Accelerated Graphics Port
The Accelerated Graphics Port (AGP is a port on the Host-
to-PCI bridge that supports and AGP. The AGP provides fast
access to system memory.
2 MB-PII
Page 13
The AGP can be used as a fast PCI port (32 bits at 66 MHz
versus 32 bits at 33 MHz), or as an AGP port supporting 2x
data rate, a read queue and side band addressing.
Expansion Slots
There are a total of seven expansion slots and one accelerated
graphics port (AGP). One slot provides an ISA bus, four
slots are PCI busses and one PCI and one ISA are shared.

Jumpers
There are two sets of jumpers that configure the motherboard
with the installed processor, and one jumper that allows you
to clear real time clock (RTC) data from CMOS RAM.These
are the CPU Bus Frequency (FS0, FS1, FS2), the CPU Core
Bus Frequency (BF0, BF1, BF2, BF3) and CLRTC.
CPU Bus Frequency FS0, FS1, FS2
These jumpers tell the clock generator what frequency to send
to the processor. This allows the selection of the processors
external frequency (or Bus Clock). The Bus Clock multiplied
by the Bus Ratio equals the processors internal freqency (the
processors advertised speed).
CPU Core Bus Frequency BF0, BF1, BF2, BF3
These jumpers set the frequency ratio between the internal
frequency of the processor and the processors external
frequency. These must be set in conjunction with the CPU
Bus Frequency jumpers.

Clear Real Time Clock CLRTC
The CMOS RAM is powered by the onboard battery. To
clear the RTC data, follow these steps:
1) Turn off the computer and unplug the AC power.
2) Short the two points labeled CLRTC by installing onto
the pins and then removing a jumper shunt.
3) Plug in the AC power and turn on the computer.
4) Hold down the <Delete> key during bootup and enter
BIOS setup to re-enter user preferences.

System Memory
Only dual inline memory ,odules (DIMMs) can be used with
this motherboard. Three sockets are available for 3.3 volt
unbuffered synchronous DRAMs (SDRAM) or EDO DRAM,
of either 8, 16, 32 64 or 128 MB to form a memory size
between 8 MB and 384 MB.
To utilize the chipsets Error Checking and Correction (ECC)
feature, you must use a DIMM module with nine chips per
side (standard eight chips/side plus one parity chip) and make
proper settings in the BIOS Chipset Features Setup.
Important: Memory speed setup is required through Auto
Configuration in BIOS Chipset Features Setup.

Note: IRQ9, IRQ10, IRQ11, IRQ12, IRQ15, IRQ3, IRQ4,
IRQ5 and IRQ7 can be redirected to PCI add-in boards.
The PCI standard has a 4-IRQ limitation. Some PCI add-in
boards do not require IRQs. Some can share an IRQ with
another board of the same model and manufacture. Check the
add-in boards documentation for IRQ information.
Direct Memory Access
The system supports seven DMA channels:
Controller 1 Controller 2
Channel 0 - Spare Channel 4 - Cascade
for Controller 1
Channel 1 - SDLC Channel 5 - Spare
Channel 2 - Diskette Channel 6 - Spare
Channel 3 - Spare Channel 7 - Spare
The first DMA controller holds channels 0 through 3. These
channels support 8-bit data transfers between 8-bit I/O
adapters and 8- or 16-bit system memory. Each channel can
transfer data in 4 KB blocks.
The second DMA controller holds channels 4 through 7.
Channel 4 cascades channels 0 through 3 to the
microprocessor. Channel 5, 6 and 7 support 16-bit data
transfers between 16-bit I/O adapters and 16-bit system
memory. These DMA channels can transfer data throughout
the 16 MB system-address space in 128 KB blocks.
Channel 5, 6 and 7 cannot transfer data on odd byte
boundaries.

Configuration Utilities
Overview
BIOS Setup is a utility that defines and stores the
configuration of the machine. When the system boots, the
machines configuration loads into memory. Drives, video
adapter, memory and keyboard are described to the system.
The program is built into the CMOS chip on the
motherboard. To start the program, press the <Delete> key
while the system is booting. The Utilities menu displays:
If you discover after making and saving system changes that
you have made a mistake, the BIOS lets you override the

without power management or green features). If set up in
your system, your screen saver will not display with Blank
Screen selected. V/H SYNC + Blank blanks the scren and
turns off vertical and horizontal scanning.
The settings are DPMS Off, DPMS Reduce ON, Blank
Screen, V/H SYNC+Blank, DPMS Standby, and DPMS
Suspend.
PM Timers
This section controls the time-out settings for the Power
Managment scheme. The fields included in this section are
HDD Power Down, which places the hard disk into its lowest
powre consumption mode, and Doze, Standby and Suspend
system inactivation modes.
The system automatically wakes up from any power saving
mode when there is system activity such as when a key is
pressed or when there is activity detected from the enabled
IRQ channels.

Power Up Control
This section determines the ways the system can be controlled
when it is started or restarted, when modem activity is
detected, or when power to the computer is interrupted and
reapplied. The Soft-Off mode refers to powering off the
system through a momentary button switch (ATX switch) or
through the software as oposed to disconnecting the AC
power by way of a rocker switch or other means.
Fan Monitor (xxxxRPM)
The onboard hardware monitor is able to detect the Chassis
Fan Speed, CPU Fan Speed and the Power Supply Fan
Speed..Set to Ignore only if necessary.
Thermal Monitor
The onboard hardware monitor is able to detect the CPU and
motherboard (MB) temperatures. These values refresh upon
keyentries. Set to Ignore only if necessary.
Voltage Monitor
The onboard hardware monitor is ale to detect the voltages
put out by the voltage regulators. These values refresh upon
key entries. Set to Ignore only if necessary.
Note: If any of the monitored items are out of range, an error
message will appear: Hardware Monitor found an error,
enter POWER MANAGMENT SETUP for details. You will
then be prompted to Press F1 to continue, DEL to enter
SETUP.
