Hmmm, two PCI bridge chips ???

Well, you left out one important detail: This appears to
be a Orion based Pentium-Pro system, and those are special :)

You will need a more recent version of the PCI code than
was compiled into the 960801-SNAP.

Yes. Find a more recent boot floppy. There was an announcement
of an "unofficial" SNAP a few weeks ago, and that one should 
fully support your system. (But I can't remember WHO sent that
announcement.)

If you can move over the AH2940 to some other system for the
installation, then this ought to work just fine, too. After
finishing the SNAP install, you'll have to rebuild the kernel
with more recent PCI code (/sys/pci/pci.c and pcisupport.c).
Move over the controller and boot disk to your Compaq after
installing the new kernel ...

Else, you'll need to build a boot floppy on another system you
have access to, or find somebody else to do it for you. (Sorry
I can't help with that, currently, for lack of resources ...)

I'm sorry for the inconvenience, but while I try to add support
for new chip sets as soon as possible, I often don't have access
to the hardware or databooks. Orion support was only recently
added for that reason (when somebody offered to do the necessary 
tests and happened to even have a databook :) ...
