I wanted to add two things. (1), Yes, the device entries exist. Sure, I can remake them but their dates of creation indicate they were just made when I installed FreeBSD, shortly before the time at which I first log in. (2), I've noticed in the boot messages that the kernel sees the SCSI controller (ahc0) but never does the "Waiting 15 seconds for SCSI devices to settle" thing, and never reports seeing the attached 8mm drive at ID #4. The SCSI controller always sees the device when I test it, by typing ^A during boot, entering the SCSI controller's onboard software interface and using it to poll the bus and see what it sees. This hardware works perfectly under FreeBSD 4.3 but not under 4.4 or 4.5; and the error reported under 4.4 and 4.5 is identical. And now, I will go off and do a 'MAKEDEV'; and, you know, I think I *did* do this, 'way back last week when I was first getting into this. But, really, if the /dev entries exist, and their major and minor numbers are as coded in /dev/MAKEDEV (which is a shellscript) remaking them should not effect anything. -- richard richard childers wrote: > I've been a happy (and loyal) user (and proponent) of FreeBSD since > version 2.2. > > After moving, recently, I was distressed to find that my server didn't > work.
