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.

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.

“Bootable Add-in Card” that is relevant to other boot sources media such as
SCSI cards and LAN cards.
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. By
default, these items are Enabled.
Hyper-Threading Technology
This feature is enabled when your processor supports Hyper-Threading
Technology. Otherwise, this field will be hidden.

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
