Anyone know why I get "Cannot find operating system" when I boot
my computer off my single SCSI drive?
******* Working on device /dev/sd1 *******
parameters extracted from in-core disklabel are:
cylinders=1029 heads=64 sectors/track=32 (2048 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=1029 heads=64 sectors/track=32 (2048 blks/cyl)
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 0 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 32, size 2107360 (1028 Meg), flag 80
beg: cyl 0/ sector 1/ head 1;
end: cyl 1023/ sector 32/ head 63
The data for partition 1 is:
<UNUSED>
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
If I boot from a different SCSI disk with DOS on it, it works fine.
How can I fix the mbr or whatever is at the beginning so bios will
run the boot strapper?
Also, with the boot loader, I have one drive on at SCSI ID 1,
the boot loader will force me to type sd(0,a)/kernel (from floppy).
It'll load it up okay, but then it will say cannot mount route device
/dev/sd0a. I have fixed tSCSI ID 1 to be sd1 in the kernel config.
