The problem is that SCSI devices are measured from 0, despite your IDE, therefore you should be saying 'sd(1,a)'... however, if you say that to the BIOS (which is used to find the /kernel file), it will try to use scsi device 0..... The 'hd' (virtual?) device overcomes this by being a combination of IDE and SCSI disks. If your BIOS sees the third disk (second scsi), try booting hd(2,a)/kernel. If your BIOS doesn't see this, you'll have to put a small (~20Mb) FreeBSD partition on one of your first two disks. -- Brian <brian@awfulhak.demon.co.uk> Don't _EVER_ lose your sense of humour....
