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 sort 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.

BIOS SETUP  
BIOS Introduction  
The Award BIOS (Basic Input/Output System) installed in your  
computer system’s ROM supports Intel® Pentium® 4 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.

The section below the setup items of the Main Menu displays the control  
keys for this menu. At the bottom of the Main Menu just below the  
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.

MB884 User’s Manual  
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 board 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.

Limit CPUID MaxVal  
The choices are:  
Enabled: Limits CPUID maximum value to 3 when used with older OS  
like Windows NT4.  
Disabled: Disables CPUID limit for Windows XP.  
Hard Disk Boot Priority  
36  
MB884 User’s Manual  
BIOS SETUP  
This item allows you to set the priority for hard disk boot. When you  
press enter, the selections shows the current hard disks used in your  
system as well as the Bootable Add-in Cardthat is relevant to other  
boot sources media such as SCSI cards and LAN cards.  
Virus Warning  
This item protects the boot sector and partition table of your hard disk  
against accidental modifications. If an attempt is made, the BIOS will  
halt the system and display a warning message. If this occurs, you can  
either allow the operation to continue or run an anti-virus program to  
locate and remove the problem.  
CPU L1 and L2 Cache  
Cache memory is additional memory that is much 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 items allow you to  
enable (speed up memory access) or disable the cache function..  
Hyper-Threading Technology  
Hyper-Threading Technology enables two logical processors on a single  
physical processor by replicating, partitioning, and sharing the resources  
within the Intel NetBurst microarchitecture pipeline.  
Quick Power On Self Test  
When enabled, this field speeds up the Power On Self Test (POST) after  
the system is turned on. If it is set to Enabled, BIOS will skip some  
items.  
First/Second/Third Boot Device  
These fields determine the drive that the system searches first for an  
operating system. The options available include Floppy, LS/ZIP, Hard  
Disk, CDROM, LAN, USB-FDD, USB-ZIP, USB-CDROM and Disable.  
Boot Other Device  
These fields allow the system to search for an operating system from  
other devices other than the ones selected in the First/Second/Third Boot  
Device.  
MB884 User’s Manual  
37  
BIOS SETUP  
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.  
Typematic Rate Setting  
When disabled, continually holding down a key on your keyboard will  
generate only one instance. When enabled, you can set the two typematic  
controls listed next. By default, this field is set to Disabled.  
Typematic Rate (Chars/Sec)  
When the typematic rate is enabled, the system registers repeated  
keystrokes speeds. Settings are from 6 to 30 characters per second.  
Typematic Delay (Msec)  
When the typematic rate is enabled, this item allows you to set the time  
interval for displaying the first and second characters. By default, this  
item is set to 250msec.  
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.  
38  
MB884 User’s Manual  
BIOS SETUP  
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
