Over some time I've installed various versions 
of FreeBSD. In the past installation has always 
gone smoothly.

Now however, I'm trying to setup a new system on
a new machine with software RAID 1 (vinum) and 
have run into difficulties (which I don't think
have anything to do with vinum).

The new machine is based on a P4SGL-VM mother 
board with a 1.7G Celeron processor and 256Mb RAM.
Two WDC WD1200JB-00DUA3 (120Gb) drives are 
installed on the primary and secondary IDE master 
ports with 80 conductor cables.

During installation it seemed to be difficult to
move sysinstall on from the fdisk and MBR dialogues 
to the the disklabel dialogue; it seemed to want to
always loop back to the beginning of the fdisk 
dialogue. But after a number of false starts managed 
to get a developer (without X) system installed on
slice ad0s1 of about 6Gb.

After some fiddling with with vinum in ad0s2 and ad2s2
I reset vinum (resetconfig) and discarded these slices.

On ad2 I created one large slice and labeled it with
a view to vinum with ad2s1a having an offset of 281
blocks and the vinum partition an offset of 16 blocks.
After creating a filesystem on ad2s1a and mounting on 
/mnt I attempted to copy the root partition from the
axisting system using:
 # cd /mnt
 # dump -0 -a -f - / | restore -f -
which reported an error something like:
 expected file 223455: found 223456
which (unfortunately) I didn't record so is only an

 # fsck -n /dev/ad0s1a
reported an inconsistency but without any real detail.

 # fsck /dev/ad0s1a
whether or not in single user mode reported (NO WRITE)
and declined to fix the problem.

When attempting to write directly to an unmounted slice or partition:
 # dd if=/dev/zero of=/dev/ad0s2 count=50
I get a message to the effect that the filesystem is 
readonly and a console message:

  fixlabel: invalid magic

and on searching the kernel source I find it in
/usr/src/kernel/subr_diskslice.c preceded by the comment

/* These errors "can't happen" so don't bother reporting details. */

The problem has appeared on both drives.
However fdisk and disklabel do not "seem" to have problems

I first attempted to set this up on another machine with the same 
brand of mother board but slightly different -- significant to us
it had an onboard network interface. On that board (same drives)
I was the installation could not access the hard drives until UDMA was 
disabled in the BIOS. Nor could the installed system operate with
UDMA turned on. Stuck with PIO4 I abandoned that machine.
(While I considered that a CD as slave on one of the IDE ports might
create UDMA difficulties on one hard drive it does not explain, to me,
lack of access to the other hard drive.)

The above is of course a very much cut down version of events.
The cost of the time spent messing about with these system has been
much greater than the cost of the hardware!

Do I have faulty hardware?
Or is the hardware incompatible with FreeBSD?
Is the hardware simply rubbish?
Am I being stupid?

Does any one have good or bad experience with these mother boards?
Does anyone understand what is happening?
