Just a wild guess; some "BIOS" (preboot program to
enumerate PCI
device and prepare various PCI matters for real OS) fail to
cope with
"two-functions-in-a-single" cards which equip two
PCI device chips.
Lately most of PC BIOS do well the job smart, however it's
likely a case
where old RISC firmware fails the similar way, I suspect.
