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.
How to download the system BIOS is described on page 87 .
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 ”
(rename the BIOS filename with the one on the floppy disk).
4 Shut down the PC Workstation.
5 Power off the PC Workstation and remove the power cord.
6 Remove the cover.
7 Set switch
7 to the ON position.
8 Insert the floppy disk into the floppy disk drive.
9 Reconnect the power cord and switch on the PC Workstation.
10 The PC Workstation boots from the floppy disk, then flashes the BIOS.
However, it should be noted, that during the flash process, the screen
remains blank.
11 The recovery process is finished when there is one very long beep.
12 Power off the PC Workstation. Remove the floppy disk from the drive.
Remove the power cord.
13 Set switch 7 back to the OFF position.
14 Replace the cover, reconnect the power cord, then reboot the PC
Workstation.
