I have had a try with a pci video card now. No change. The Bios and 
video card do not post anything to
the display. In fact the screen (CRT) doesn't even wake up. Thus I 
believe the system is not being
initialised at all. The floppy drive is not polled at all. The light on 
the floppy drive doesn't come on and the
floppy doesn't 'click' like they normally do when the floppy starts to 
read a disk.

Ah, well I don't believe the ROM boot block is in tact. The floppy as 
indicated above is not being polled.
Even with an autoexec.bat file on the disk to run the flash utility, 
nothing happens.

Understood, however I can account for every jumper on the motherboard. I 
can visually match each jumper
to the plan in the mobo book and there are no other jumpers.

I have been trying this, both just with the clear cmos jumper and doing 
that as well as removing the cmos
backup battery and the power to the board.

The bios flash chip is in a socket - Not Soldered. Specifically, it is 
in a 32 pin PLCC32 package.
I have confirmed that I can remove the flash chip from the socket.

So it seems I am back to my original question. I need a supplier of 
flash chips (in Perth) that can also write the
flash image that I bring with me onto the chip.

I appreciate the help Arie.
