G'day Stefan. Let me guess; you're still insanely busy? 8)
I've been poking a little at this Intel 450NX-based system we have
here, trying to get some sort of handle on why we only see one of the
three PCI busses on the system.
Following are the relevant verbose boot and mptable output. Any ideas?
>From the 450NX chipset documentation it almost looks as though there
are three separate PCI busses off the host bus, rather than being
bridged off each other; they make mention of one bus being in
"compatibility" mode.
We'd obviously really like to support the other two busses in this
machine...
