Vista - Radeon X850 problem with RC2

I have a PC Chips M848A motherboard and an AGP Radeon X850 video card.
I set up my machine as a dual boot with Vista RC2 but cannot get the
video card drivers to install. I have let Windows download and
install it's own and I have tried downloading the driver from ATI's
website for Vista (they are labled RC1 but I don't know if that really
matters). Anyway, Windows disbables the video card and keeps flashing
a message off of a yellow triangle icon on the tray that it has been
disabled because it is not compatible with the VGA adaptor. Since
this happens with with Micorsoft and ATI's driver, I think the problem
may be with the driver for the AGP port itself. Anyone run into
anything similar?

Thanks.

Th problem could also be that your MOBO BIOS needs to be updated for RC1 or
later. I am seing better results from users with RC2 using the ATI drivers
that come with RC2 then with the RCs drivers from the ATI Website.

I'm having the same problem and the roll back driver option is grayed out.
Not all mobo manufacturers are putting out new updates. It seems to be an
ongoing problem with Msoft, ATI and Nvidia. I mean, come on Microsoft, our
hardware isn't that new.

Unfortunately, I cannot find any newer bios or integrated component
driver upgrades than what I have. I am going to keep checking the
mobo manufacturer's web site for upgrades, though.
