Same problem with RC1 (2 supported video cards don't work, only the primary
card as set in the BIOS works). I've seen a lot of complaints about this and
no solutions. I don't know that Vista supports multi video cards at
present... Thought RC meant feature complete?!?!

Does Vista Beta 2 support dual monitors yet?

I cannot get two video cards running at the same time after a lot of
testing. I have tried the following combos.

Radeon 9250 and a Radeon 850xt plat (1 PEG , 1 PCI )
Radeon 850xt plat and Gforce 5500 (1 PEG , 1 PCI )
Radeon 9250 and Gforce 5500 ( 2 PCI )

With those hw combos and every combo of driver available (from posted beta
drivers for vista and XP drivers and even with standard VGA drivers) The
second card (regardless of which one) always gets an error 43 or error 10 on
load.

Anyone have thoughts on what to try?

Many thanks
