This model has an on-board adaptec controller this is what seen, during the boot, it is a different controller to the PCI-UW2SCSI unit you are trying to use, which is likely to be an AMI Mega RAID or an adaptec RAID of some kind (depending on which Dell re-badged) The AMI unit is supported in cureent ( and I believe should be bootable) There is an experimental version of the driver back ported to stable available from mike smith, bu I think you will still have to boot from the on board adaptec or an IDE disk ATM. For the moment I suggest you try boot floppies from: ftp://current.freebsd.org/pub/FreeBSD/snapshots/i386/4.0-19991115-CURRENT/ to confirm they can see the disk. You should be able to search the mailing lists at www.freebsd.org for amr0, Dell PERC, or AMI and RAID to find docs / details for the driver. > > Where have my disks gone?
