Hi,

The quick story: after a change of the MB from a GA-7VT600 1393
to a GA-7VT600-L, both with VIA Apollo KT600 / 8237 cipset, my
system's preen fsck can't find the superblock on partitions other that
/ As far as I can say the fs where clean (note however that / was
mounted read-only AFAIR).

I've googled around half a day and the hole night with no luck. The
system was first on a KT400/8235 mobo and i've moved it with no
problem. What is different now ? It has been installed with the
defaults newfs options.

Questions:
1. "in-core disklabel" means what is read from the disk ?
2. The sizes are OK, the root slice is OK and I can use it, the first
FAT32 XP partition is OK and I can boot XP, what makes the diference
between / and the others ?
3. If the slightly different BIOS is to blame, how to make the newfs
when installing so that I will not have this problem again in the
future ?
4. Besides McKusick's paper from 44doc what other sources of
information on ufs are there ?
5. And, of course :-/ , how to get my data back ?

I can provide a dumpfs and/or ffsinfo, if someone cares to see them
(btw, they still are in 5.1 ? as in the on-line man pages thy are not)

#fsck -p

A fsck -t ufs ad0s2d gives:
** /dev/ad0s2d
Cannot find file system superblock
/dev/ad0s2d: INCOMPLETE LABEL: type 4.2BSD fsize 0, frag 0, cpg 0,
size 1048576

and fsck_ffs -b 32 isn't of much help either.

******* Working on device /dev/ad0 *******
parameters extracted from in-core disklabel are:
cylinders=232578 heads=16 sectors/track=63 (1008 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=232578 heads=16 sectors/track=63 (1008 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:

beg: cyl 0/ head 1/ sector 1;
end: cyl 1023/ head 254/ sector 63
The data for partition 2 is:

The BIOS -> LBA reads 14593/255/63 and in dmesg, next to ad0 it is
232578/16/63.
If I'm booting with the live CD I get:
Offset Size(ST) End
