goodmorning, am a newbye of "tape units" and am experiencing a related problem in short : having weed# uname -a FreeBSD weed.rfc1925.net 8.1-RELEASE FreeBSD 8.1-RELEASE #0: Mon Jul 19 02:55:53 UTC 2010 root@almeida.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC i386 the HP device seem to be recognized weed# dmesg .......[snip out some unrelated lines ] ahc0: <Adaptec 2902/04/10/15/20C/30C SCSI adapter> port 0xd000-0xd0ff ahc0: Host Adapter Bios disabled.
