：
When system boots up without the MONITOR attached during the POST, the
VBIOS will disable the MONITOR output. Under this condition, the MONITOR display will not work and the system will need to be rebooted with the
MONITOR attached to enable the display. The problem originates from the
VBIOS of the IntelR Extreme Graphics Driver, which disables the MONITOR output if a MONITOR is not detected during POST.

Award BIOS Setup
AR-B1851 User’s Guide
4.1 Introduction
This chapter discusses the Setup program built into the BIOS. The
Setup program allows users to configure the system. This configuration is then stored in battery-backed CMOS RAM so that it retains the Setup information while the power is off.
4.2 Starting Setup
The BIOS is immediately active when you turn on the computer. While the BIOS is in control, the Setup program can be activated in one of two ways:
1. By pressing <Del> immediately after switching the system on, or
2. By pressing the <Del> key when the following message appears briefly at the bottom of the screen during the POST (Power On Self-
Test).
Press DEL to enter SETUP.
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 pressing <Ctrl>, <Alt>, and <Delete> 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...

Save & Exit Setup
Pressing <Enter> on this item asks for confirmation:
Save to CMOS and EXIT (Y/N)?
Y
Pressing “Y” stores the selections made in the menus in CMOS – a special section of memory that stays on after you turn your system off.
The next time you boot your computer, the BIOS configures your system according to the Setup selections stored in CMOS. After saving the values the system is restarted again.

Use this menu to load the BIOS default values that are factory settings for optimal performance system operations. While Award has designed the custom BIOS to maximize performance, the factory has the right to change these defaults to meet their needs.
When you press <Enter> on this item you get a confirmation dialog box with a message similar to:
Load Optimized Defaults (Y/N) ? N
Pressing ‘Y’ loads the default values that are factory settings for optimal performance system operations.
Exit Without Saving
Pressing <Enter> on this item asks for confirmation:
Quit without saving (Y/N)?
Y
This allows you to exit Setup without storing in CMOS any change. The previous selections remain in effect. This exits the Setup utility and restarts your computer.
Load Fail-Safe Defaults
Use this menu to load the BIOS default values that are factory settings for safety system operations.
When you press <Enter> on this item you get a confirmation dialog box with a message similar to:
Load Fail-Safe Defaults (Y/N) ? N
Pressing ‘Y’ loads the default values that are factory settings for
Fail-Safe system operations.

Appendix A. Watchdog Timer
The WDT(Watch Dog Timer)is used to generate a variety of output signals after a user programmable cont. 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.
WATCHDOG TIMER SETTING
The watchdog timer is a circuit that maybe be used from your program software to detect crash or hang up. The watchdog timer is automatically disabled after reset. Once you enabled the watchdog timer, your program should trigger the watchdog timer every time before it times out. After you trigger the watchdogtimer, the timer will be set to zero and start to count again. If your program fails to trigger the watchdog timer before times out, it will generate a reset pulse to reset the system or trigger the IRQ9 signal in order to tell your system that the watchdog time is out.
User could test watch dog function under ’Debug.exe’ program as follows:
WDT Example Description o 2e 87 o 2e 87 o 2e 07

;EFIR=EFER(Extended Function Index

Appendix B: Digital I/O
One characteristic of digital circuit is its fast response to high or low signal. This kind of response is highly needed for harsh and critical industrial operating environment. Digital Input and
Output, generally, are control signals. You can use these signals to control external devices that needs On/Off circuit or
TTL devices. You can read or write data to the selected address to enable the function of digital IO.
Users could test GPIO function under ‘Debug.exe’ program as follow:
