I don't have the BIOS installed, because I boot from a SCSI disk :-( I thought it can't be that bad because I'm much faster than the normal DMA stuff using the onboard IDE controllers and boot -v shows udma settings and anyway I can't think of a reason why the channels are synchronized without the BIOS. Next thing to try after I copied my boot parition. As I think over it, a /boot.conf entry could be sufficient. If you're right, my plan seems to work. Cheap fast space :-))) Thanks Martin -- %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Martin Cracauer http://www.cons.org/cracauer Tel.: (private) +4940 5221829 Fax.: (private) +4940 5228536 Paper: (private) Waldstrasse 200, 22846 Norderstedt, Germany To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
