Recovering the BIOS (Crisis Mode)
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 113
.
3
Create (or edit) the file, AUTOEXEC.BAT
This should contain a single line of text:
“
phlash /c /mode=3 /s IQ0105US.FUL
”
(rename the BIOS filename with the one on the floppy disk).
4
Power off the PC and remove the power cord.
5
Remove the cover.

Set switch
7
to the
ON
position.

Insert the floppy disk into the floppy disk drive.
8
Reconnect the power cord and switch on the PC.

The PC boots from the floppy disk, then flashes the BIOS. However, it
should be noted, that during the flash process, the screen
remains blank.
