Hi,
I'm currently only able to boot my laptop from a 1.4 CD I made some time ago.
The machine boots fine using 'boot wd0a:netbsd' but fails with all mbr's I've
tried and boot selectors. I've only just noticed that the info produced by
fdisk looks wrong. The output from disklabel looks ok. So from the following
info can anyone suggest what I need to do to fix this?
The first partition is Win2K, the second is 1.4 and will be 1.4.2 when I
can find the disk space on my other machine to build the new userland etc.
disklabel:
# /dev/wd0d:
type: unknown
disk: FREYA
label:
flags:
bytes/sector: 512
sectors/track: 63
tracks/cylinder: 15
sectors/cylinder: 945

rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0 # milliseconds
track-to-track seek: 0 # milliseconds
drivedata: 0
8 partitions:
# size offset fstype [fsize bsize cpg]

and fdisk:
