Add ISA PnP system devices describing the ISA bus and PCI devices as
well as the presence of the APM BIOS. Prior to this fix, Windows 95
did not automatically sense ISA Plug & Play devices nor did it see
anything on the PCI bus, and APM support only appeared if you installed
Windows 95 with it enabled. This update gives Windows 95 all the PnP
information it needs to automatically see PnP devices on the ISA bus and
automatically scan and work with the PCI bus.
