One thing you can do would be to boot up and do the following: dd if=/dev/mem bs=0x400 count=1 of=idt.out dd if=/dev/mem bs=64k iseek=15 count=1 of=bios.out Then place those files some place I can fetch them. You might also play with any BIOS settings you have for serial console redirection to see if they make a difference. -- John Baldwin
