I have tested Nvidia pci-e graphics card ( I forgot the model) and
Mellanox pci-e infiband card with all Tyan opteron based MB. All work
well.

Also I test another eight way four ck804 system with 4 infiband pci-e
card, it works well too.

Subject: [LinuxBIOS] Opteron nVidia CK8-04/nForce4 PCI Express support

Does the current LinuxBIOS code support PCI Express?  LinuxBIOS
contains PCI Express support code, but does it actually work?

Has anyone successfully used a PCI Express SATA controller via
LinuxBIOS with an nVidia CK8-04/nForce4 chipset?  Or a PCI Express
video card?  Or any PCI Express card or device?

I have an nVidia CK8-04 CRB mainboard.

Here's lspci output using LinuxBIOS (GNU Arch Rev 33) code, ported
from the Tyan S2895 to nVidia CK8-04 CRB (with Fedora Core 3 running):

I'm not sure about the bus numbering being correct for LinuxBIOS.
Somewhere, I heard that the bus nmubers for certain devices had to be
multiples of 0x40 for the CK8-04 chipset, but I can't recall which
devices and why they had to be on bus 0, 40, 80, & C0.  As you can see
above, LinuxBIOS and PhoenixBIOS use very different bus numbers.

The onboard ATA, USB (pen drive) and Ethernet eth0 (didn't try eth1)
are working.

Right now, I'd like to test PCI Express.  It would be great to have a
PCI Express bus analyzer and execizer, but they are very expensive.
I think the cheapest and easiest way to test PCI Express is via
a PCI Express SATA controller or maybe a PCI Express video card.

I'm planning to get the following PCI Express cards:

Siig SCSAE012S1 SATA II PCI Express card
http://www.directron.com/scsae012s1.html

ATI Radeon X300 SE 128MB PCI Express card
http://www.ati.com/products/radeonx300/specs.html

Is there anything wrong with my plan to use either of these particular
PCI Express cards to test PCI Express on my nVidia CK8-04 CRB?

To test PCI Express with the video card I would need to use testbios
or the integrated VGA support of LinuxBIOS?  It seems that this could
get too complicated for just testing that PCI Express works.  The PCI
Express SATA controller seems much easier.  Is there an easier way to
test PCI Express with the PCI Express video card such as simply
reading and writing to its RAM (in other words, not using it as a
video device)?

Thank you!

Sincerely,
