BIOS SETUP  
BIOS Introduction  
The Award BIOS (Basic Input/Output System) installed in your  
computer system’s ROM supports Intel processors. The BIOS provides  
critical low-level support for a standard device such as disk drives, serial  
ports and parallel ports. It also adds virus and password protection as  
well as special support for detailed fine-tuning of the chipset controlling  
the entire system.  
BIOS Setup  
The Award BIOS provides a Setup utility program for specifying the  
system configurations and settings. The BIOS ROM of the system stores  
the Setup utility. When you turn on the computer, the Award BIOS is  
immediately activated. Pressing the <Del> key immediately allows you  
to enter the Setup utility. If you are a little bit late pressing the <Del>  
key, POST (Power On Self Test) will continue with its test routines, thus  
preventing you from invoking the Setup. If you still wish to enter Setup,  
restart the system by pressing the ”Reset” button or simultaneously  
pressing the <Ctrl>, <Alt> and <Delete> keys. You can also restart by  
turning the system Off and back On again. The following message will  
appear on the screen:  
Press <DEL> to Enter Setup  
In general, you press the arrow keys to highlight items, <Enter> to  
select, the <PgUp> and <PgDn> keys to change entries, <F1> for help  
and <Esc> to quit.  
When you enter the Setup utility, the Main Menu screen will appear on  
the screen. The Main Menu allows you to select from various setup  
functions and exit choices.

control keys section, there is another section, which displays information  
on the currently highlighted item in the list.  
Note:  
If the system cannot boot after making and saving system  
changes with Setup, the Award BIOS supports an override to  
the CMOS settings that resets your system to its default.  
Warning: It is strongly recommended that you avoid making any  
changes to the chipset defaults. These defaults have been  
carefully chosen by both Award and your system  
manufacturer to provide the absolute maximum performance  
and reliability. Changing the defaults could cause the system  
to become unstable and crash in some cases.

BIOS SETUP  
Standard CMOS Setup  
“Standard CMOS Setup” choice allows you to record some basic  
hardware configurations in your computer system 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. You will need to  
run the Standard CMOS option, however, if you change your system  
hardware configurations, the onboard battery fails, or the configuration  
stored in the CMOS memory was lost or damaged.

CPU L1 and L2 Cache  
Cache memory is additional memory that is faster than conventional DRAM  
(system memory). CPUs from 486-type on up contain internal cache memory,  
and most, but not all, modern PCs have additional (external) cache 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. These allow  
you to enable (speed up memory access) or disable the cache function.  
MI940 User’s Manual

These fields allow the system to search for an OS from other devices  
other than the ones selected in the First/Second/Third Boot Device.  
Swap Floppy Drive  
This item allows you to determine whether or not to enable Swap Floppy  
Drive. When enabled, the BIOS swaps floppy drive assignments so that  
Drive A becomes Drive B, and Drive B becomes Drive A. By default,  
this field is set to Disabled.  
Boot Up Floppy Seek  
This feature controls whether the BIOS checks for a floppy drive while  
booting up. If it cannot detect one (either due to improper configuration  
or its absence), it will flash an error message.  
Boot Up NumLock Status  
This allows you to activate the NumLock function after you power up  
the system.  
Gate A20 Option  
This field allows you to select how Gate A20 is worked. Gate A20 is a  
device used to address memory above 1 MB.

Security Option  
This field allows you to limit access to the System and Setup. The default  
value is Setup. When you select System, the system prompts for the User  
Password every time you boot up. When you select Setup, the system  
always boots up and prompts for the Supervisor Password only when the  
Setup utility is called up.  
APIC Mode  
APIC stands for Advanced Programmable Interrupt Controller. The  
default setting is Enabled.  
MPS Version Control for OS  
This option is specifies the MPS (Multiprocessor Specification) version  
for your operating system. MPS version 1.4 added extended  
configuration tables to improve support for multiple PCI bus  
configurations and improve future expandability. The default setting is  
1.4.  
OS Select for DRAM > 64MB  
This option allows the system to access greater than 64MB of DRAM  
memory when used with OS/2 that depends on certain BIOS calls to  
access memory. The default setting is Non-OS/2.  
Report No FDD For WIN 95  
If you are using Windows 95/98 without a floppy disk drive, select  
Enabled to release IRQ6. This is required to pass Windows 95/98's SCT  
test. You should also disable the Onboard FDC Controller in the  
Integrated Peripherals screen when there's no floppy drive in the system.  
If you set this feature to Disabled, the BIOS will not report the missing  
floppy drive to Win95/98.  
Small Logo (EPA) Show  
The EPA logo appears at the right side of the monitor screen when the  
system is boot up. The default setting is Disabled.

C. Watchdog Timer Configuration  
The WDT is used to generate a variety of output signals after a user  
programmable count. The WDT is suitable for use in the prevention of  
system lock-up, such as when software becomes trapped in a deadlock.  
Under these sorts of circumstances, the timer will count to zero and the  
selected outputs will be driven. Under normal circumstance, the user  
will restart the WDT at regular intervals before the timer counts to zero.
