Hi Ben, sorry for the late reply ( Motherboard crash),

The system I'm trying to setup is an IBM SurePOS 500. It is supposed to
work on a FB console (no X) in order to play some Videos :)
I'm able to use a usb to vga in order to accomplish this but, using the
integrated Radeon was preferable.
So, you're saying that it is probably a BIOS related issue, not
initializing the secondary Video card. Is there anyway I can make sure
of it? If the BIOS is not initializing it properly, I may be able to
contact IBM about it.

Once again, thanks a lot for your help,
