Thanks for the ideas, Mick. I'll think them over overnight. Another idea I've had is that I've got duff RAM. The various bootable images that crash don't always crash in _exactly_ the same places. And the BIOS mouse and keyboard freezing up don't inspire confidence. I do hope it's not the RAM; I'd probably have to remove the processor cooler just to be able to get at the RAM sticks. :-( > HTH. > -- > Regards, > Mick -- Alan Mackenzie (Nuremberg, Germany).
