Hmm, what makes you think that "the PCI spec supports 4" regions only?
OK, I have to admit that I only have the 2.0, not the 2.1 spec at hand
currently, but that one certainly talks about all 6 regions without
making any difference between them (at least I cannot find any).
If your BIOS supports only 4 of those regions, i.e. it only allocates
space for 4 of them, it certainly looks to me like a bug in the BIOS
implementation.
Is there anything that you can do about it in the BIOS configuration menus?
Ciao,
Wolfgang
