This will make copying the CD onto the Jaz drive tricky. If the files on the CD are all 8.3 filenames, then you should be able to proceed with a "filesystem install" with no trouble. If not, you may have to reformat the Jaz drive with a big UFS partition and copy the stuff from there. You might even be able to do this by booting the boot floppy on the machine with the CD-rom drive in something like the following manner: NOTE: many of these commands can clobber whole disks in a serious and unreparible way. Make sure you know what you are doing and have backups. Also, as you go through this, you may need to create device files in /dev with MAKEDEV. See the handbook. 1) Boot the boot disk, go to the fixit menu, get a shell prompt. 2) edit /etc/disktab to add as disktab entry for the jaz drive. I lifted mine out of the handbook somewhere: jaz1gb|Iomega Jaz 1GB - FreeBSD: \ :ty=removable:dt=SCSI:se#512:nt#64:ns#32:nc#1021:rm#5394:\ :pa#2090976:oa#0:ba#4096:fa#1024:ta=4.2BSD:\ :pc#2090976:oc#0: 3) use disklabel to write a new label into a slice on the jaz drive. If your jaz drive is like mine were, the DOS partition is in slice 4 so you'll use a command like: disklabel -w -r /dev/sd2s4 jaz1gb assuming that the jaz drive showed up as sd2. (NOTE: I'm not 100% sure that this command is right and it can mess up your disks if it is wrong. Read the man pages) 4) use disklabel to edit the partition table for the slice you just created and create a big partition. disklabel -e /dev/sd2s4 My partition table looks like: # size offset fstype [fsize bsize bps/cpg] a: 2090976 0 4.2BSD 0 0 0 # (Cyl. 0 - 1020*) c: 2090976 0 unused 0 0 # (Cyl. 0 - 1020*) 5) Newfs the partition. In this case, use (I think) newfs /dev/sd2s4a 6) Mount up the CD and the jaz drive with something like: mkdir /cdrom mkdir /jaz mount -t cd9660 /dev/cd0a /cdrom mount -t ufs /dev/sd2s4a /jaz 7) Copy the CD your favorite way. I'd use: cd /cdrom tar cf - . | (cd /jaz; tar xf -) But there are lots of good (probably better) ways to get this done. 8) Shutdown the machine, haul your new FreeBSD 2.2.1-RELEASE jaz drive over to the new machine and boot it up with the jaz drive and try it out. Making jaz drives work for the first time under FreeBSD is a bit tricky, but once they work you can treat them just like any other SCSI disk.
