My goal was to dedicate the drive to use under FreeBSD, so I'm trying to get it working, but I've run into some funny problems. As background, the standard AHA kernel for FreeBSD 2.0 reports this on boot: ahb0 not found aha0: 1542C/CF detected, unlocking mailbox aha0: reading board settings, dma=5 int=11 (bus speed defaulted) aha0 at 0x330-0x333 irq 11 drq 5 on isa aha0 waiting for scsi devices to settle aha0 targ 0 lun 0: type 0(direct) fixed SCSI2 aha0 targ 0 lun 0: <QUANTUM LPS270S 590W> sd0: 258MB (528808 total sec), 2740 cyl, 2 head, 96 sec, bytes/sec 512 I also made sure to set up the appropriate entries in /dev as follows: brw-r----- 1 root operator 4, 0 Sep 28 11:43 sd0a brw-r----- 1 root operator 4, 1 Sep 28 11:43 sd0b brw-r----- 1 root operator 4, 2 Sep 28 11:43 sd0c brw-r----- 1 root operator 4, 3 Sep 28 11:43 sd0d brw-r----- 1 root operator 4, 4 Sep 28 11:43 sd0e brw-r----- 1 root operator 4, 5 Sep 28 11:43 sd0f brw-r----- 1 root operator 4, 6 Sep 28 11:43 sd0g brw-r----- 1 root operator 4, 7 Sep 28 11:43 sd0h Unfortunately, when I try to disklabel the drive, disklabel complains that sd0 hasn't been configured! Once again-- this controller/drive combo works great under DOS/Windows, but FreeBSD isn't very happy with it. It seems odd that the disk *is* recognized during boot, but later on disklabel claims it's not configured. What am I missing!?!?!?!?! The FAQ doesn't seem to have any specific info, so I'm finally breaking down and asking for HELP! Thanks.... -Roy
