Description Ahmed Benani 1999-12-05 18:10:00 UTC 
I'm using NEC PC-9821RvII (It's not PC-AT compatible).
After I got bootstrap message `Ross(?)', I cannot use PCI bus.

Fix: It seems that reading from 0x45 has no meaning on my machine.
Without following patch, my machine reports like this.

pcib255: <Ross (?) host to PCI bridge> on motherboard

And no other PCI devices are found, cannot mount root device, then panic.
It seems that pci_cfgread() returns 0xff.

PC9821RvII uses Champion as it's chip set. Champion is product of
Reliance Computer, I beleive. So, I feel strange about message `Ross(?)'.
`RCC' is more precise?

This patch was committed in rev. 1.52 of src/sys/i386/isa/pcibus.c. 
Quite a few other changes have been made to the file since then as well. 
I'm guessing this is no longer a problem...is it OK for me to close 
this PR?
