Centos 4.1 (x86_64) On Precision 670

I have been trying to get Centos 4.1 x86_64 (RHEL4 clone w/o RH branding) installed on my 670 but am having problems with GRUB or maybe the scsi controller I am not totally sure at this point. Basically, the installation goes perfectly no errors, but upon rebooting I receive the word GRUB at the prompt and nothing more. I brought up the distro in rescue mode and performed a manual GRUB install. After doing that I now get past stage 1.5 on boot but then the boot process stops with the following message:

Grub loading, please wait...
Error 2

Pertinent System configuration is as follows:
2 146GB 15K SCSI drives configured for raid0 via adaptec u320 (aic-7901A) HostRaid

Note: The linux installer does not see the Raid0 configuration because it shows 2 146GB scsi drives. However, it does recognize and load the AIC-79XX driver. At this point I have tried many types of installs and am just trying to get it to boot before trying to get a Raid configuration working under linux (whether it be Linux software raid or the built in raid). Currently I am only using the first scsi disk and have just a single bootable root partition. My grub.conf looks as follows:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You do not have a /boot partition. This means that
# all kernel and initrd paths are relative to /, eg.
# root (hd0,0)
# kernel /boot/vmlinuz-version ro root=/dev/sda1
# initrd /boot/initrd-version.img
#boot=/dev/sda

root (hd0,0)
kernel /boot/vmlinuz-2.6.9-11.EL ro root=/dev/sda1
initrd /boot/initrd-2.6.9-11.EL.img


*Any* help on this is greatly appreciated as I am totally frustrated at this point and have no clue how to get this working. I am also willing to try other (free) x86_64 distros if someone has one working on a like configured 670.

Thanks,
