Dimension 9150 BIOS bugs

[Rik van Riel]

Hi,

I think I have found a few BIOS bugs in the Dimension 9150, while
trying to get a second video card (to drive my 3rd monitor) to work.

1) When adding a second PCIe video card (PCIe x1 Matrox G550), the
    BIOS does not reserve the PCI resources (like IO memory) that is
    needed to actually make the card usable.  The system hangs hard
    when trying to use the card.

2) I then added a 256MB PCI video card to the system (Radeon 9250),
    which works.  However, the system now shows 512MB less system
    memory than before, instead of "just" 256MB...

3) This is probably more of a fundamental limitation, but it would
    be really nice if the BIOS knew how to remap memory above the 4GB
    limit.  Or at least not lose twice as much RAM as is actually used
    by the PCI cards.

I believe I have the latest BIOS version:

         Vendor: Dell Inc.
         Version: A04
         Release Date: 04/19/2006

If you have any information about these problems or fixes for them,
please let me know.

kind regards,

Rik van Riel
