There are operating systems that simple conflict with some assumptions
made by PCI architecture.
Rembember that the PC memory map changed to include the PCI
configuration space and so on, space that can be expected to contain
other data, or not at all, and could be used in ISA/EISA/VLB/MCA
systems by PCI-unaware operating systems or applications.

Hi,
Seabios seems to have some assumptions built in that break when -M
isapc
is selected. Is this supposed to work or is isapc about to die?
Does anything actually require isapc?
pc has an ISA bridge, a PCI VGA device is still VGA/SVGA compliant.
Would anything break if we just dropped isapc?
