I'm wondering why these use cases can't simply use the 'pc' machine
type?
The early pci chipsets of the 90-ies have been designed in a
backward-compatible manner, with devices such as the IDE controller
being mapped to the standard ISA ioports. So even an historic OS which
does not know what PCI is can run on that hardware, by simply talking to
devices using the standard ISA io ports ...
take care,
Gerd
