AR-B1375/AR-B1376 User s Guide

7.6.2 Auto Configuration with Fail Safe Setting

User can load the Fail-Safe BIOS Setup option settings by selecting the Fail-Safe item from the Default section of the BIOS Setup main menu.

The Fail-Safe settings provide far from optimal system performance, but are the most stable settings. Use this option as a diagnostic aid if the system is behaving erratically.

Load failsafe settings (Y/N) ?

7.7 BIOS EXIT

This section is used to exit the BIOS main menu in two types situation. After making your changes, you can either save them or exit the BIOS menu and without saving the new values.

7.7.1 Save Settings and Exit

This item set in the <Standard CMOS Setup>, <Advanced CMOS Setup>, <Advanced Chipset Setup> and the new password (if it has been changed) will be stored in the CMOS. The CMOS checksum is calculated and written into the CMOS.

As you select this function, the following message will appear at the center of the screen to assist you to save data to CMOS and Exit the Setup.

Save current settings and exit (Y/N) ?

7.7.2 Exit Without Saving

When you select this option, the following message will appear at the center of the screen to help to Abandon all Data and Exit Setup.

Quit without saving (Y/N) ?

7.8 BIOS UPDATE

The BIOS program instructions are contained within computer chips called FLASH ROMs that are located on your system board. The chips can be electronically reprogrammed, allowing you to upgrade your BIOS firmware without removing and installing chips.

The AR-B1375/AR-B1376 provides FLASH BIOS update function for you to easily upgrade newer BIOS version. Please follow the operating steps for updating new BIOS:

Step 1: Turn on your system and don’t detect the CONFIG.SYS and AUTOEXEC.BAT files. Keep your system in the real mode.

Step 2: Insert the FLASH BIOS diskette into the floppy disk drive.

Step 3: In the MS-DOS mode, you can type the AMIFLASH program.

A:\>AMIFLASH

Step 4: The screen will show the message as follow:

Enter the BIOS File name from which Flash EPROM will be programmed. The File name must and with a <ENTER> or press <ESC> to exit.

Step 5: And then please enter the file name to the box of <Enter File Name>. And the box of <Message> will show the notice as follow. In the bottom of this window always show the gray statement.
