It's wonderful, that you found a way to make the PCI probe work on your system, but there would have been a much simpler way to achieve this, and that would have been to not do the probe, but directly return the specific results for your system ... Compaq PCI chip sets have been broken in similar ways for a long time, and I received a reply from Compaq, that this is taken care of in their PCI BIOS. That's fine, but we don't rely on any PCI BIOS, since there are more broken PCI BIOS versions than broken PCI chip sets. } Of course we had to add "options COMPAQ" to the config file.

Building the "official" boot floppies is a complex and time consuming process. but it is in fact possible to create a BSD FFS on a floppy, copy /kernel and a few other required files over, and boot from this floppy. Don't ask for details, I didn't try it recently ...
