Unable to install on IDE drive

I am currently running XP and would like to install Vista Beta 2 as a second
OS. XP is running on an SATA RAID 1 setup. I am trying to install Vista on
my additional 28GB IDE drive.

Here is my problem. When doing a bootable install and selecting the 28GB
drive, I get the message, "Windows is unable to find a system volume that
meets its criteria for installation." I have tried formatting through the
bootable install, followed by creating a new partition, and still get the
same message.

I tried another method - installing from XP. This time, I am able to select
the desired drive and continue. However, now I get another error:

************************************
Install Windows
------------------
At least one device driver that might be required to start your system is
not available.
Devices with missing drivers:

NVIDIA nForce(tm) RAID Class Controller
ST3160812AS
NVIDIA MCP51 Serial ATA Controller

Do you want to ignore this warning and continue with the installation?
(YES/NO)

********************************

When I select 'yes', the installation proceeds normally and successfully
copies files to the drive followed by a reboot. However, during the Vista
Setup reboot I get the blue screen of death. Upon rebooting in Safe Mode, I
see the lockup is after the system tries to load the drive.sys driver.

When I select 'no', the installation gives another message saying to boot
from the installation media, run setup, and load necessary boot-critical
drivers. I have also tried loading these drivers from my motherboard CD, but
without any success (ASUS A8N-VM). The CD contains drivers for both 32 and
64-bit versions of XP, among other OS drivers.

Any ideas to get through a successful installation?

Thanks,
