+Currently, GNU Mach requires the presence of the BIOS32 Service Directory for PCI access.
+The other possible methods are direct access, which is somewhat dangerous and using mmconfig, the preferred default in Linux.
+Direct access is already supported, but only used if BIOS32 is present for safety reasons.
+The relevant Linux code could be adapted and reused.
