Force BIOS flash, Switch 9 (XA models) or
10 (XW and XA-s models) Down Position
WARNING:
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. This floppy diskette
contains all the recovery and system BIOS programming 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 9 (XA models) or,
Set Switch 10 (XW, XU and XA-s models) to the DOWN position (=on).
4 Insert the DOS-bootable diskette (refer to the above warning).
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).
WARNING: For Kayak XU Series 03xx, XA-s Series
02xx and XA Series 05xx, a specific 'Mini-Dos'
bootable disk has to be used. An image of this
'Mini-Dos' bootable floppy can be obtained from
the Alps/Info server (not available from the
external web site). If you do not have access to the
Alps/Info server, contact your escalation team.
