Recovering System BIOS - switch 1
Switch 1 enables recovery of the old system BIOS after an attempt to update has failed.
To restore the old BIOS you need a Flash BIOS Diskette (call customer service). The
existing BIOS settings are meaningless for restoring the system BIOS (e.g. the
Security
menu in the
Flash Write
field).
OFF
The System BIOS is started with the system BIOS from the system board
(default setting).
ON
The system is started from the Flash BIOS Diskette in drive A. A recovery
of the system BIOS is executed.

If switch 1 is set to
ON
, switch 3 must be set to
OFF (OPEN)
.

BIOS can be carried out, write protection for the system BIOS must also be disabled in
the
BIOS Setup

Flash Write
field must be set to
Enabled
). If you wish
to update your system BIOS, please consult our customer service.

System BIOS can be overwritten (default setting).

System BIOS is write protected.
Write protection for floppy disk drive - switch 4
