Unfortuantely, since Non-PnP cards and PnP cards BOTH fall into the category of ISA Cards, you can't [easily] have the luxury of probing the ISA Non-PnP cards first. There just really isn't an easy way to seperate the non-PnP and PnP Cards. > Welcome to the wonderful world of ISA and reason #1 why there is no > such thing as PnP for an ISA machine that doesn't have PnP extensions > on the motherboard itself. My motherboard has no support for PnP- It was manufactured years before PnP was even dreamed of. This is kind of the catalyst for writing support for PnP-devices in FreeBSD. If your motherboard supports PnP, then you have a fairly reliable configuration for each PnP card (which is handled by Bios, before the boot sequence is started). For poor folks like Amancio and I, we have to leave it to the operating system to handle PnP configuration. Sujal
