Hi Christopher - thanks for following this up. As the machine was a dual boot with Windows Vista (32 bit) I rebooted the machine into Windows to perform the BIOS upgrade. I ran the .exe file you pointed me at, then ran the 32-bit version of flash.bat from a DOS prompt. The old BIOS was erased and the new one appeared to be written ok. Then the machine was shut down by the program. However it won't boot up again! All I get when I switch the PC on is a low humming noise that lasts indefinitely. I see nothing at all on the screen - no BIOS info, nothing. I'm writing to you from a different machine now.
So it strongly looks like the BIOS upgrade failed:(. I have to go to work now but I'm hoping you'll be able to advise me on how to recover the machine when I get back. Presumably there's some way of getting a BIOS onto a new PC before any OS is installed since the BIOS has to be there first? I'm happy to try with the new BIOS again, or, if that fails, somehow get hold of the original BIOS version again. But right now my smoothly working machine has been transformed into an almost dead lump of metal:(.
