There were 3 ways the probes responded to my de0. One didn't see it at all. Another assigned it to IRQ 15 same as the VL-bus Adpatec was hard jumpered to use. And the 3rd was as shown with "irq ??" I wasn't trying to share an IRQ between a PCI device and anything else. It did it all by itself. And I was asking how to control it.

Try turning the "PnP OS installed" option off. Ah, a clue! OTOH its a 1994 BIOS with a last rev date of 1996. Not so sure it has PnP. It does have the AMI "WinBIOS". > Interesting that the collection of boards that have this behaviour are > just hitting the collection of users that have to ask about it.

It (de0) worked with FreeBSD 2.2.2. On removal of the VL-bus Adpatec the only remaining thing changed in hardware has been an upgrade from 16 MB plain non-parity memory to 32 MB of EDO. How do I query my local cvs archive for a history of changes in the de driver? The syntax escapes me. But I have figured out how to checkout versions as of a certain date. Shooting for that date isn't any fun. Will look for PnP. Will try selecting "BIOS Defaults" too as others have suggested. Won't be near that machine again until Thursday. Meanwhile it continues to run off the ISA NE2000. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
