Recovery Boot Active Procedure (Force BIOS flash, Switch 10 Down Position)
Recovery Boot Active Procedure
(Force BIOS flash, Switch 10 Down Position)
If, for example, during a BIOS flash, the procedure is interrupted by a power
failure, and the system does not restart, then you can force a BIOS flash.
However, it should be noted that during the procedure, there is no image on
the screen, nor access to the keyboard or mouse (only “vital” devices that
are required to boot on the floppy device are initialized)
.
To force a BIOS flash, do the following steps:
1 Ensure that you have created a DOS-bootable diskette (1.44 MB diskette
only). This floppy diskette contains all the recovery and system BIOS pro-
gramming software (phlash.exe, platform.bin and hb1xxxyy.Ful). Include
the flash command in the autoexec.bat, for example: phlash /mode=3
hb1xxxyy.Ful
2 Turn off the computer.
3 Set Switch 10 to the DOWN position (=on).
4 Insert the DOS-bootable diskette.
5 Power on the computer.
6 During the recovery process, short beeps are emitted. The recovery
process is finished when there is a much longer beep (approximately
around 1 to 2 minutes).
7 Power off the computer. Press the power ON/OFF button (for about 5
seconds), until the ON/OFF light switches off. Set the Switch 10 to the UP
position (=off).
