: IIRC, "PNP OS = Yes" is a hack for Windows 95 (I've actually seen some
: BIOSs refer to it as "Running Windows 95" instead of "PNP OS").

Parts of the PCI and PnP initialization are explicitly *not* done if this
option is set to "Yes"; Win9x has code to go in and set up the PCI bus
manually and allocate IRQs at runtime to make use of this.

We do provide some support for the various PCIBIOS and PnPbios calls
involved in 1.5.x and -current, but most of it is not enabled by default.
Your best bet is to set this option to "no".
