I have an A7S8X-MX board with onboard video and I'm trying to setup
dual display with onboard+ATI7500AiW card but failed. When I switched
to enable dual display and initial video on AGP, neither video works
after reboot - need to clear BIOS to get back in. I'm not sure what
I'm missing. What's the proper way to set this up?

One thing for sure is suspecious is that the option for 'video share
memory' is missing in the BIOS. What could be the cause?

I don't think it is possible to have 2 AGP- graphics adapters working in the
machine at the same time.

Egil,

Hey do you're saying that the onboard video runs on the AGP bus as
well, even though the slot is not used? What I found is that I can now
get the onboard video to boot up but once the driver for onboard is
installed properly, the ATI hardware 'disappear' and is not showing up
on the 'hardware device'.
