You don't say exactly where the problem starts. But I assume that you have checked to see if you can turn off DMA from the BIOS. Anyway, I did a bit of looking around and found these. The second one is interesting because it may offer a solution. In any case, you might want to try posting to debian-boot, maybe someone there has the definitive solution. http://lists.debian.org/debian-boot/2004/debian-boot-200401/msg00794.html http://lists.debian.org/debian-boot/2004/debian-boot-200401/msg00279.html -- ....................paul It is important to realize that any lock can be picked with a big enough hammer. -- Sun System & Network Admin manual -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
