Software Raid and Kernel Panic (from wiki page) [SOLVED]

I am trying to setup a RAID 5 array using the instructions on the wiki:

http://wiki.archlinux.org/index.php/Ins … AID_or_LVM

I get through the instructions (have actually done it several times now) and get the following error:

.....

FDC 0 is a post-1991 82077

VFS: Cannot open root device "md0" or unknown-block(0,0)

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

The grub menu.lst

root   (hd0,0)
kernel /vmlinuz26 root=/dev/md0 ro

I setup three partitions on IDE drives

/dev/md0  -  root   (8 GB / drive)
/dev/md1  -  boot  (100 MB / drive)
/dev/md2  -  swap  (1 GB / drive)

I have three drives for the area with three partitions on each:

hda1 - boot
hda2 - swap
hda3 - root

I did skip the LVM step in the wiki pages.

fstab

The system is a dual PIII using the arch ISO 7.1 release.

Any thoughts on what is wrong with my setup?  Or something I can try.  I'm game for just about anything in my test environment to try and get it working.

Thanks,
Chris....

Re: Software Raid and Kernel Panic (from wiki page) [SOLVED]

After the basketball games where over tonight I had a thought (and a little research).  The install iso I was using was a pre-release of 0.7.1.  When I downloaded the real mccoy and did a fresh install following the instructions on the wiki, all worked flawlessly!
