Hi there:
On a Compaq Proliant 1600, ROM Rev E31. This machine has 6 PCI
slots which according to the docs, are in two different PCI
busses. Slots 4-6 are in the first bus, slots 1-3 are in the
second. The problem is that any PCI cards plugged
to the PCI slots 1 to 3 are not seen by the FreeBSD
probes. Cards in slots 4-6 are probed fine.
The problem is that I need to install 2 NICs and 2 ahc controllers
on this server.
This is the relevant info from a boot -v

Perhaps the PCI bridges are not being recognized correctly?
I have physical access to the PCs and can provide specific chip
numbers if req'd. I can also do a lot of testing on this as it's
not yet in production ('till this is fixed :)
Thanks a lot in advance.
