The way that both the FreeBSD driver and the EISA configuration utitlity tell this is by doing a chip reset on the card and looking for a specific value in a register. Someone in the Linux camp had this happen to a 2740 that had been working fine for some time. He said that pulling the adaptor out and reinserting it in the slot fixed the problem. It might be worth a try. >On boot the channel B is being probed (of course there's nothing >there). Is this normal? Well, does it hang your system? If not, then don't do anything. If it does, you can disable the B-channel probe in the driver. Just take a look at the ahc_attach routine in i386/scsi/aic7xxx.c. >Note that this system also has a BusLogic BT-747S with two disks, >which is where the FreeBSD system is installed and is booting from. > >Thanks, >-- >Bob Willcox >bob@obiwan.pmr.com (or obiwan%bob@uunet.uu.net) >Austin, TX -- Justin T.
