If you want a warning message to pop-up or a warning alarm to sound when an abnormal condition occurs, you must install the Hardware Doctor utility. This utility is included in the CD that came with the system board. Refer to the Hardware Doctor Utility section in chapter 4 for more information.

RTC Timer to Power-on the System

The RTC installed on the system board allows your system to automatically power-on on the set date and time.

Power On Function

This function allows you to use the keyboard or mouse to power-on the system. Refer to Setting the Power On Function in chapter 3 for more information.

Note :

1. The power button will not function once a keyboard password has been set in the KB Power On Password field of the Integrated Peripherals submenu. You must type the correct password to power-on the system. If you forget the password, power-off the system and remove the battery. Wait for a few seconds and install it back before powering-on the system.

2. The 5VSB power source of your power supply must support 720mA (minimum). If you are using the Suspend to RAM function, the 5VSB power source must support a minimum of 1.2A.

AC Power Failure Recovery

When power returns after an AC power failure, you may choose to either power-on the system manually, let the system power-on automatically or return to the state where you left off before power failure occurs. Refer to Selecting the Power Lost Resume State in chapter 3 for more information.

Year 2000 Compliant

ACPI

The system board is designed to meet the ACPI (Advanced Configuration and Power Interface) specification. ACPI has energy saving features that enables PCs to implement Power Management and Plug-and-Play with operating systems that support OS Direct Power Management. Currently, only Windows 98 supports the ACPI function. ACPI when enabled in the Power Management Setup will allow you to use the Suspend to RAM function.

With the Suspend to RAM function enabled, you can power-off the system at once by pressing the power button or selecting Standby when you shut down Windows 98 without having to go through the sometimes tiresome process of closing file, applications and operating system. This is because the system is capable of storing all programs and data files during the entire operating session into RAM (Random Access Memory) when it powers-off. The operating session will resume exactly where you left off the next time you power-on the system. Refer to Using the Suspend to RAM Function in chapter 3 for more information.

The ROM chips of your mainboard are configured with a customized Basic Input/Output System (BIOS) from Award Software Inc. The BIOS is a set of permanently recorded program routines that give the system its fundamental operational characteristics. It also tests the computer and determines how the computer reacts to specific instructions that are part of programs.

The BIOS is made up of codes and programs that provide the device level control for the major I/O devices in the system. It contains a set of routines (called POST, for Power-On Self Test) that check out the system when you turn it on. The BIOS also includes CMOS Setup programs, so no disk-based setup program is required. CMOS RAM stores information for :

< the date and time

< the memory capacity of the mainboard

< the type of display adapter installed

< the number and type of disk drives installed.

The CMOS memory is maintained by a battery installed on the mainboard. By using the battery, all memory in CMOS can be retained when the system power switch is turned off.

Use the CMOS Setup program to modify the system parameters to reflect the options installed in your system and to customize your system as desired. For example, you should run the Setup program after you :

< replace the battery

< install another disk drive

< receive an error code at startup

< use your system after not having used it for a long time

< find the original setup missing

Run the CMOS Setup program after you turn on the system. On-screen instructions explain how to use the program.
