Keith,

true! I have not tested the code on non-PCI system due to missing hardware 
and completely forgotten the option to use qemu -isa for testing. Anyway, 
I would expect code to only print warning message about missing PCI BIOS 
and otherwise not harm at all, thought I will not be able to test it on 
qemu in the near future. If you will do testing yourself, please keep us 
posted!

Thanks,
Karel
