SATA boot crash

I get garbage displayed as soon as either the MBR or stage 1 is loaded,
and the machine crashes. I've just installed two brand new Western
Digital WD3200YS disk in a (debian) RAID-1 configuration. I have an
Intel PERL 2.8GHz motherboard.

I'm currently booting from a grub floppy until I can fix this. The
previous disks in the machine were IDE disks, and grub worked fine. The
new disks have all the old data, so all the grub files are present.

I installed grub like so:

grub> device (hd0) /dev/sda
grub> root (hd0,0)
grub> setup (hd0)
grub> device (hd0) /dev/sdb
grub> root (hd0,0)
grub> setup (hd0)

Here's some info about the disks:

    # hdparm -I /dev/sda


    ATA device, with non-removable media
            Model Number:       WDC WD3200YS-01PGB0

            LBA48  user addressable sectors:  625142448
            device size with M = 1024*1024:      305245 MBytes
            device size with M = 1000*1000:      320072 MBytes (320 GB)

Here's my grub config:

    # cat /boot/grub/menu.lst 
    default         0
    timeout         5
    color           cyan/blue white/blue

    root            (hd0,0)
    kernel          /boot/vmlinuz- root=/dev/md0 ro

Here's the version info about grub:

    # dpkg -l grub | grep grub
    ii  grub    0.97-16.1    GRand Unified Bootloader
