My testing showed that it worked as of 2000.08.22.00.00.00, but not as of 2000.08.23.00.00.00 - I manually backed out each commit, until (I think) I proved it was those commits. > > This motherboard only has one IDE channel... at least, only one > > connector, and it's only designed to go to the CD-ROM.

In any case, whatever happened needs to be fixed, so that someone popping a CD in a new setup doesn't get a panic. -- Kevin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
