MEMORY INSTALLATION
No jumper setting is necessary for DRAM setting, BIOS will check DRAM
type and size automatically. B598 motherboard contains 2 by 168-pin DIMM
sockets(DIMM1,DIMM2). B598 motherboard has table-free ( or auto-bank )
feature and user can install DIMM into any bank. The Two DIMMs Sockets for
system memory expansion from 8MB to 256 MB. Each bank provides 64-bit
wide data path.

Award BIOS ROM has a built-in Setup program that allows users to
modify the basic system configuration. This type information is stored in
battery-backed RAM so that it retains the Setup information when the power is
turned off.
ENTERING SETUP
Power on the computer and press <Del> immediately will allow you to
enter Setup. The other way to enter Setup is to power on the computer , when
the below message appears briefly at the bottom of the screen during the POST
(Power On Self Test), press <Del> key or simultaneously press <Ctrl>, <Alt>,
and <Esc> keys.
TO ENTER SETUP BEFORE BOOT PRESS CTRL-ALT-
ESC OR DEL KEY
If the message disappears before you respond and you still wish to enter
Setup, restart the system to try again by turning it OFF then ON or pressing the
"RESET" button on the system case. You may also restart by simultaneously
press <Ctrl>, <Alt> and <Del> keys. If you do not press the keys at the correct
time and the system does not boot , an error message will be displayed and you
will again be asked to,

This category flashes on the screen. During and after system boots up, any
attempt to write to the boot sector or partition table of the hard disk drive will
halt the system and the following error message will appear, in the mean time ,
you can run anti-virus programs to locate the problem.

CPU Internal Cache/External Cache
These two categories speed up memory access. However, it depends on
CPU/chipset design. The default value is Enabled.
Enabled: Enabled cache

Quick Power On Self Test
This category speeds up Power On Self Test (POST) after you power on the
computer. If it is set to Enable, BIOS will shorten or skip some check items
during POST.
Enabled: Enable quick POST
isabled: Normal POST
Boot Sequence
This category determines which drive computer searches first for the hard disk
operation system (i.e., DOS).
A, C,SCSI: System will first search for floppy disk drive then second
search hard disk driver, then SCSI driver.

B598

driver.
SCSI,A,C: System will first search SCSI hard disk driver then second
search for floppy disk driver then IDE hard disk driver.
C ROM,C,A:
System will first search for the CDROM driver ( If the CDROM
has a bootable CD title.)and second search hard disk driver then
floppy disk driver .
C,C ROM,A:
System will first search for the hard disk driver and second

title,) then search floppy disk driver.
LS120,C: System will first search LS120 disk driver and second search
for IDE hard disk driver.
Swap Floppy Drive
Users can enable this item so that the BIOS will see the hardware "Drive A:" as
"Drive B:", and hardware "Drive B:" as "Drive A:".
Boot Up Floppy Seek
During POST, BIOS will determine if the Floppy disk drive installed is 40 or
80 tracks. 360 K type is 40 tracks while 720K, 1.2M and 1.44M drive type as
they are all 80 tracks.
Enabled: BIOS searches for floppy disk drive to determine if it is 40 or 80
tracks. Note that BIOS can not tell from 720K, 1.2M or 1.44M
drive type as they are all 80 tracks.
isabled: BIOS will not search for the type of floppy disk drive by track
number. Note that there will not be any warning message if the
drive installed is 360K.
