Chapter 4 <BIOS Setup>
The single board computer uses the Award BIOS for the system configuration. The
Award BIOS in the single board computer is a customized version of the industrial
standard BIOS for IBM PC AT-compatible computers. It supports Intel x86 and
compatible CPU architecture based processors and computers. The BIOS provides
critical low-level support for the system central processing, memory and I/O
sub-systems.
The BIOS setup program of the single board computer let the customers modify the
basic configuration setting. The settings are stored in a dedicated battery-backed
memory, NVRAM, retains the information when the power is turned off. If the battery
runs out of the power, then the settings of BIOS will come back to the default setting.
The BIOS section of the manual is subject to change without notice and is provided here
for reference purpose only. The settings and configurations of the B IOS are current at
the time of print, and therefore they may not be exactly the same as that displayed on
your screen.
To activate CMOS Setup program, press <DEL> key immediately after you turn on
the system. The following message “Press DEL to enter SETUP” should appear in the
lower left hand corner of your screen. When you enter the CMOS Setup Utility, the Main
Menu will be displayed as Figure 5-1. You can use arrow keys to select your function,
press <Enter> key to accept the selection and enter the sub-menu.

EFIR : Extended Fun ction Index Register. ( Same addr . with EFER. )
EFDR : Extended Funct ion Data R egister .( Located at addr.[ EFIR +1 ] )
For instance ;
(*1) Enter extended function mode
MOV DX,2EH
MOV AL,87H

LD8-CRF7- Bit[3..0] : Select IRQ resource for WDT time-out
( Setting of 2 selects SMI )
(3) WDT Programmimg g uide
Step 1 . Enter extended function mode as mentioned as above.
Step 2 . Program WDT related CR.
(2-1) CR2B-b[4]P[0] ; Set pin output as WDT function
(2-2) CR07-P08h ; Point to LD8
(2-3) CRF6-Pxyh
; Program WDT time-out period an d start
count down . xy = 00 ; No WDT time-out and counting
xy = 01 ; WDT time-out = 30 sec. and starts counting .
............
(2-4) Read CRF7-b4 if needed ; 0 : WDT counting
1 : WDT time-out happened
Step 3. Exit e xtended function mode as mentioned as above.
Example (ENABLE WDT AND SET WDT time-out = 5 minutes)
Step 1 .

REMARK :
**** I/O PORT 2Eh --> Index port for programming CR .
2Fh --> Data port for programming CR .
**** LD8-CRF6-P05 h :
Program CR index F6h of Logical Device 8
with the value "05h" .
