I wasn't sure that the 2.1-RELEASE supported the 2940 Ultra series. I guess it does since you've gotten as far as you have. If you have extended translation enabled in SCSI Select Utilites, then you want the geometry to be 255 heads and 63 sectors. Otherwise, the 64/32 heads/sectors is correct. FreeBSD can't determine the disk geometry unless there is already a partition on the drive. A simple method of ensuring correct geometry is to make a small DOS partition on the drive and then boot FreeBSD using the install disks. You can delete the DOS partition if you don't want it from within the partition editor during the install. You'll want to upgrade to FreeBSD-stable as soon as you can because there were some bug fixes made to the aic7xxx driver. Hope this helps, Dan Eischen deischen@iworks.InterWorks.org
