Hi Jailbait. Thanks for the reply. I've put the relevant bits from the messages log below. This is when booted up to FC1 which is running off the IDE controller card.

Dont know if you can make any sense of this. The IDE controller card seems to be detected ok. What I can't understand is, after the POST I can boot up FC1 with a floppy, and yet I can't create a link from GRUB in the MBR of hda to GRUB in hde1, so as to boot FC1 from GRUB in hde1
cat /proc/interrupts shows that the IDE controller card is shared with the USB as below.

Does this look like it should to you? Nigel. aka farpoint.
