Hi again!

During FreeBSD 7.1 installation, I made some changes to my BSD
partitions. I didn't touch ad0s1h (/home), so there is still my data.
Installation went good, but I see "disk boot failure..." error message
when trying to boot OS. Using Fixit liveCD I see:
#fdisk /dev/ad0
******* Working on device /dev/ad0 *******
parameters extracted from in-core disklabel are:
cylinders=3D119705 heads=3D16 sectors/track=3D255 (4080 blks/cyl)

Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=3D119705 heads=3D16 sectors/track=3D255 (4080 blks/cyl)

Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:

partition c: partition extends past end of unit
bsdlabel: partition c doesn't start at 0!
bsdlabel: An incorrect partition c may cause problems for standard
system utilities
partition h: partition extends past end of unit

So, slice ad0s1 is active, partitions can be mounted and viewed, all seems =
OK.
boot0cfg -B /dev/ad0 and fdisk -B /dev/ad0 doesn't solve the problem.

What did I mess? What does the last strings of bsdlabel output mean?
How do I manage this?



Thank's in advance for any advice.
