Details:

I tried compiling grub 0.97, patched as mentioned here:

http://documents.jg555.com/netboot/x86-pxe-config.html

to try to provide (forcedeth) support for the gigabit controller on an Asus
A8N-SLI motherboard. PXE on the motherboard downloads and runs pxegrub, but
grub can't locate the ethernet controller, "Probing pci nic...failed". I also
tried compiling the patched grub with "--enable-pci-direct" - same results.
After looking at NVIDIA's documentation for this ethernet controller

http://www.nvidia.com/object/IO_8451.html

(linked to from here: http://www.nvidia.com/page/pg_20041015215635.html)

I'm thinking that its not necessarily a problem with the driver for the
ethernet controller but rather grub's inability to probe the bus its on;
seems rather obvious given grub's "Probing pci nic...failed" message. Has
anyone found a solution to enable non-PCI ethernet controllers in pxegrub? I
realize this list is for Legacy Grub issues, but does anyone know if GRUB 2
will address this kind of problem? Does my uninformed theory about why grub
can't find the ethernet controller have any merit?
