Vista Ultimate x86 or x64 will not install to SATA drives - ok to IDE

Subject line states the problem and before anyone suggests that I need to
install the SATA drivers during the install process - I have. Have tried
both the 32 and 64 bit drivers.

Hardware:

Asus A8N32-SLI Deluxe motherboard
AMD Athalon X2
2Gb memory
WDC Raptor 74Gb 10Krpm drives on SATA (x2)
Seagate EIDE drives (x2)
GeForce 6800 graphic cards (x2)

During install, Vista does install to the SATA drive but when it goes to
first boot, it reboots then comes up to a black screen - no error messages.
I believe Vista is not recognizing the SATA drives (Sil 3132 SATA controller
on Asus mb) even though the drivers were loaded during the install process.

Have tried both the 32 and 64 bit Vista installs using the correct SATA
drivers and even without installing the SATA drivers during the install
process, I get the same result.

Now I'm thinking it's Vista not recognizing the SATA drives because if I
load Vista to a standard EIDE drive - it works just fine. When I look at
the system, Vista does not see the SATA drives until after you do the first
update and it does download a Sil 3132 update. Then it finds all the SATA
drives.

So even though the drivers are loaded up-front, Vista doesn't appear to
"retain" them. I've done numerous clean installs and dual boot scenarios
and it's the same story - blank screen after first reboot, no error
messages. I've reformatted the drive used to install Vista after each
attempt.

I've checked all the manf sites for info and I haven't read about anyone
else here not being able to load to SATA drives.

One thing I haven't tried is pulling an ATI TV tuner card I have installed.
I would think it would just come up as an unknown device and press on, but
then again.

Any suggestions short of booting this thing into next week........;-)

Thanks,
