F.3 EMERGENCY PROCEDURE
To run an emergency procedure, proceed as follows:
1. Remove battery jumper W5 to disconnect the battery from the board circuitry.
2. Install the EMERGENCY diskette in the floppy drive A (1.44MB) connected to the
PCI-934 board.
3. Power on the board. (Nothing appears on the screen.)
4. The Boot Block Flash update will be completed when you see POST code 55 (when
using a POST code card; see table below) or hear the associated beep code (see table
below) or when the floppy drive stops. If you see POST code 22, 33 or 44, an error has
occured. You should repeat the emergency procedure. If repeated attempts at updating
the boot block flash fail, that is, you are unable to generate POST code 55, contact the
TEKNOR Technical Support department.
5. After the procedure is successfully completed, power down the board, set your battery
jumper as it was previously and power up the board. Your PCI-934 boot block flash
BIOS should be correctly programmed and the system should run properly.
NOTE
If the emergency disk has been lost, see section G.2: Making an
Emergency Diskette.
