KP915GV Product Manual

4.9.1 Normal Mode

This is the factory default position the jumper should be in for normal operation of the motherboard.

4.9.2 Configure Mode

The Configure mode forces the BIOS into Setup with the manufacturer defaults loaded. The mode

should be returned to normal before re-starting.

4.9.3 Recovery Mode

The Recovery mode expects a recovery disk in floppy disk drive A and will wait until one is found

before performing the recovery operation.

4.10 BIOS Update and Recovery

Note: Always refer to the applicable “read me” file available in the BIOS Configuration Tools

section of the 915 boards Technical Support Library under the Products section of the

RadiSys web page “www.radisys.com.” Also note that some BIOS updates will require that

the BIOS bootblock be unlocked by moving the jumper. Be sure to return the jumper to the

original position when the update is completed.

4.10.1 Update

The update process requires two files:

• The new BIOS file (e.g., newbios.bin)

• The upgrade utility (awdflash.exe).

Although it may be possible to use different media for the files, this manual assumes that you are

using a floppy disk. (The system HDD may need to be used if the file sizes exceed the floppy disk

capacity.) Prepare for the upgrade process as follows:

• Create a bootable floppy disk.

• Transfer the two Award files listed above onto the diskette.

• Check and configure the BIOS write-protection jumper.

You are now ready to start the upgrade process.

• Boot the system to DOS environment.

• Type awdflash newbios.bin /py /sn /wb in DOS Prompt Line and press ENTER

• Wait for upgrade process end, then power off the system.

• Set JP1 to location 1-2 for a few seconds to clear CMOS data and

then set back to normal location 2-3.

• Check and configure the BIOS write-protection jumper.

CAUTION

Do not interrupt the upgrade program while it is running! Interrupting the program leaves the

system without BIOS and renders the system unusable. If the power goes off during the few

seconds that the program is running, the system will be left without a working BIOS and it will be

necessary to install a correctly programmed flash EPROM.

4.10.2 Recovery

The recovery process should be used to recover a system BIOS when the motherboard no longer

operates after a failed BIOS update operation. The process is described below.

• Create a bootable floppy disk as in the Update section.

• Create a AUTOEXEC.BAT and following command included ‘AWDFLASH ****.BIN /py/sn/wb/r’

• Check and configure the operation mode jumper to recovery mode.
