Recovering System BIOS - switch 2
Switch RCV enables recovery of the old system BIOS after an attempt to update has failed. To
restore the old system BIOS you need a Flash BIOS Diskette (please call our customer service
center).
On
The System BIOS executes from standard floppy drive A: and the inserted "Flash-
BIOS-Diskette" restores the System BIOS on the system board.
Off
Normal operation (default setting).
Write protection for floppy disks - switch 3
Switch 3 is used to define whether floppy disks can be written or deleted in the standard floppy disk
drive. To write and delete floppy disks, the write-protection in
BIOS Setup
must be disabled (in menu
Security
, the field
Diskette Write
must be set to
Enabled
).
On
The standard floppy disk drive is write-protected.
Off
Read, write and delete floppy disks is possible (default setting).
Clock frequency - switches 5 to 8
New processors select the clock frequency automatically. The settings of the switches 5 to 8 will be
ignored.
!
The switches may only be set as specified in the tables below for the particular processor
used.
There are also processors, which automatically always operate at the proper frequency,
regardless of the switch position.
As these new processors do not differ externally from the previous processors, we
recommend always setting the switches in accordance with the processor.
This system board you may use with Pentium II processors with 100 MHz Front Side Bus
