BIOS Setup
Boot To OS/2
This allows you to run the OS/2® operating system with DRAM larger than
64MB. When you choose No, you cannot run  the OS/2® operating system
with DRAM larger than 64MB. But it is possible if you choose Yes.
Internal Cache
Cache memory is additional memory that is much faster than conventional
DRAM (system memory). When the CPU requests data, the system transfers
the requested data from the main DRAM into cache memory, for even faster
access by the CPU. The setting controls the...

APIC Function
This field is used to enable or disable the APIC (Advanced Programmable
Interrupt Controller). Due to compliance to PC2001 design guide, the system
is able to run in APIC mode. Enabling APIC mode will expand available
IRQs resources for the system. Settings: Enabled, Disabled.
MPS Table Version
This field allows you to select which MPS (Multi-Processor Specification)
version to be used for the operating system. You need to select the MPS ver-
sion supported by...

Configure SDRAM Timing by
Selects whether DRAM timing is controlled by the SPD (Serial Presence
Detect) EEPROM on the DRAM module.  Setting to SPD enables
SDRAM Frequency, SDRAM CAS# Latency, Row Precharge Time, RAS
Pulse Width, RAS to CAS Delay and SDRAM Bank Interleave auto-
matically to be determined by BIOS based on the configurations on the
SPD.  Selecting User allows users to configure these fields manually.

BIOS Setup
SDRAM Burst Length
This setting allows you to set the size of Burst-Length for DRAM.  Burst-
ing feature is a technique that DRAM itself predicts the address of the
next memory location to be accessed after the first address is accessed.
To use the feature, you need to define the burst length, which is the ac-
tual length of burst plus the starting address and allows internal address
counter to properly generate the next memory location.  The bigger the
size, the faster the DRAM...

AGP Comp. Driving
This field is used to adjust the AGP driving force.  Selecting Manual
allows you to select an AGP driving force in Manual AGP Comp.
Driving.  It is strongly recommended to select Auto to avoid causing any
system error.
Manual AGP Comp. Driving
This item specifies an AGP driving force.
AGP Fast Write
This field enables or disables the AGP Fast Write feature. The Fast Write
technology allows the CPU to write directly to the graphics card without
passing anything...

Power Management Features
IPCA Function
This item is to activate the ACPI (Advanced Configuration and Power Man-
agement Interface) function. If your operating system is ACPI-aware, such as
Windows 98SE/2000/ME, select Yes.
ACPI Standby State
This item specifies the power saving modes for ACPI function. If your oper-
ating system supports ACPI, such as Windows 98SE, Windows ME and Win-
dows 2000, you can choose to enter the Standby mode in S1(POS) or S3
(STR) fashion through the setting...

USB Wakeup From S3
This item allows the activity of the USB device to wake up the system from
S3 (Suspend to RAM) sleep state.
Power Management/APM
Setting to Enabled will activate an Advanced Power Management (APM)
device to enhance Max Saving mode and stop CPU internal clock.
Power/Sleep LED
This item configures how the system uses power LED on the case to indicate
the sleep/suspend state. Available options are:

Set WakeUp Events
Press  and the following sub-menu appears.
Wake Up On PME, Resume On KBC (with “Wake-Up Key” and
“Wake-Up Password”), Resume On PS/2 Mouse
These fields specify whether the system will be awakened from power

PNP/PCI Configurations
Plug and Play Aware O/S
When set to Yes, BIOS will only initialize the PnP cards used for booting. The
rest of the cards will be initialized by the PnP operating system like Win-
dows
® 98, 2000 or ME. When set to No, BIOS will initialize all the PnP cards.
