The option are used to put HT device on specific bus num and device
logic.

Are you testing new HT device on socket?

Thank you for the answer.

What are the options for?
Why did you put them in if they break things?

How?

Yes, I am. And the code in get_bus_conf.c does not allow me to do
so unless I modify it to expect the PCI-X bridge on another logical
bus. Essentially, the modified code searches the bridge on the bus
number pci1234[1], if not found, it searches it on the bus number
pci1234[2]. And if the bridge is not there, it is a catastrophe,
unless Tyan makes boards without a PCI-X bridge.

Yes, S2865 which I'd like to use with LinuxBIOS, has no PCI-X bridge.
