I have access to a compaq 5500 that has 8 pci slots. The first four slots
and the last four slots, according to compaq's sales literature are each
behind their own host to pci bridge chip. When booting freebsd it
recognizes and scans only one of the pci busses, though it sees both of
the host to pci bridge chips. Are there allowances for such a
configuration in the current pci layer?
