Summary first, more detail about each step below: 1) make sure your kernel supports your SCSI controller, build and install one that does if you need to do so 2) power down 3) install the SCSI card and drive 4) boot DOS and install a DOS partition (AKA slice) table using fdisk 5) boot FreeBSD (single-user) off your IDE drive 6) BSD partition the FreeBSD slice on the SCSI disk with the partition sizes you want, installing boot blocks using disklabel(8). Make notes for step 9 below 7) make file systems on the ufs partitions using newfs(8) 8) use a dump/restore pipe to copy your IDE partitions to your SCSI partitions 9) edit the /etc/fstab file to change wd0 references to sd0 references 10) powerdown 11) remove IDE drive, turn off IDE in CMOS 12) boot off SCSI, you're done Addl. explanation: 4) not absolutely necc., you can BSD label the entire disk in 6) (AKA "dangerously dedicated" mode) but it can be tricky to write the label to the disk as the area it is written to is r/o by default. I forget the steps you need to take to do it but you can find them in the mailing list archives. To use DOS fdisk you would create a DOS partition for the entire disk and then delete it before going to step 5). 6) you may want to print out the man page for disklabel(8) before doing this 7&8) e.g.: # newfs /dev/rsd0a # mount /dev/sd0a /mnt # dump 0fs - 10000000 | (cd /mnt ; restore rf -) # umount /mnt If you need more explanation than that I'd be happy to try and help you.
