No, but LinuxBIOS does a pretty good job doing so.

I gathered from the wiki that linux cant handle a totally
uninitialized pci bus and that linux is close to doing that. Im trying
to read the pci sources in hopes of being able to make linuxbios work
with my kt600 motherboard. So if linux 2.6.17 can already initialize a
totally uninitialized kt600 pci bus then i might start playing with
linuxbios. all thats left is figuring out how to initialize  the dram
controller.

LinuxBIOS will set up your PCI devices correctly. The big question is
how to get dram working indeed. Can you provide an lspci output to the
list?

Well thats great.

Yes when i get home.

Is there some hope that the kt600 is somehow similar to other
supported via chipsets?
