Sorry you got this one wrong, Max is right. The HAL sets the base
addresses. There is a boot.ini switch /PCILOCK to indicate that the
addresses setup by the BIOS not be touched. I spent many a painful
day learning about this on a project where we had to get two machines
to boot identically.

PS. In general Linux is not a good reference on how NT or most of the
other OS'es on Intel platforms work.
