Recovering The BIOS (crisis mode)
If for some reason the BIOS is corrupted and the standard flash cannot be used, use the
BIOS Recovery Mode (exceptional BIOS recovery operation) to restore the BIOS. To do
this:
1. Obtain a bootable DOS floppy disk.
2. Copy the BIOS files on to the floppy disk.
3. Create (or edit) the file, AUTOEXEC.BAT
This should contain a single line of text:
“phlash /c /mode=3 /s IX.W1.XX.FUL”
4. Rename the BIOS filename with the one on the floppy disk.
5. Shut down the workstation.
6. Power off the workstation and remove the power cord.
7. Remove the cover.
8. Set switch 7 to the ON position.
9. Insert the floppy disk into the floppy disk drive.
10. Reconnect the power cord and switch on the workstation.
11. The workstation boots from the floppy disk, then flashes the BIOS. However, it
should be noted, that during the flash process, the screen remains blank.
12. The recovery process is finished when there is one long beep.
13. Power off the workstation. Remove the floppy disk from the drive. Remove the power
cord.
14. Set switch 7 back to the OFF position.
15. Replace the cover, reconnect the power cord, then reboot the workstation.
