I have just got my Fujitsu 2263S setup as boot drive with all the 2.0
software on it. Here is how I did it.

1. Follow page 168 of "Network and System Adminitration" to configure
   the disk using the following detailed description on jumper setting
   posted by Izumi Ohzawa (izumi@violet.berkeley.edu).
   I setup the scsi-id to 2. The drive is already internally
   terminated.
   
   The only difficulty I encountered was to conect the cable in the
   enclosure to the disk. There is no way to tell whether pin 1 of
   the  cable conect to pin 1 of the disk or pin 50 of the disk.
   But, I have only two choices. I get it right the second time.

[1] Jumper settings on the drive

  (a) SCSI target# can be set by jumber block "CN9" located right
	next to the SCSI bus connector of the drive.  Three jumpers
	closest to the SCSI connector encode the target number in
	binary.

	View from the back of the drive, with the drive UP-SIDE DOWN.

     |-----------|  |----------------------------|       .......
     | power con.|  |   50 pin SCSI connector    |   CN9 .......
     |-----------|  |----------------------------|       \-/
		                                          ID

	For SCSI target# 0, remove the three left-most jumpers on CN9.
	For SCSI target# 1, keep the left-most one, and remove the
		second and third jumper from left.

  (b) Remove two jumpers at both ends of the jumper block "CNH2".

	Locate the jumper block "CNH2" betweeen two surface-mount VSLI's
	whose labels are obscured by capacitors ( 1cm square blocks
	colored blue on my drive, with two leads).
	There are 8 jumpers in this block.

           On Jumper Block "CNH2" remove:
                        [1-2]      INQUIRY DATA
                        [15-16]    Synchronous Mode Transfer

	If you can't figure out the numbers on the block,
	[1-2] is at one end and indicated by a little triangle mark, and
	[15-16] is at the other end (8-th position from the triangle).

	Thank you! ]

2. Power down and bring the disk to my school's NeXT lab.

3. Following page 172 of "Network and System Administration" to build
   the system software on the hard disk. An optical disk containing
   the entire 2.0 software is used. Be careful, do NOT build "MyDisk"
   build the "UntitledDisk". It takes about an hour.
   
   Skip step 4. described in page 173.

4. Bring the disk home and connect the drive to the nextstation 
   then power up.

6. Modify the file etc/fstab in the EXTERNAL disk with the following line
   commented out. It should be possible to do this at the end of step 3.
   (I can not remember where the disk was mounted.)

   /dev/sd0b/clients 4.3 rw, noquota 0 2

   (Again Izumi gave this information. I do not understand why I need 
    to do this and I didn't do it with my first try. The drive boots
    with my mouse frozen and I have to use the NMI moditor to get out.)

7. Power down the computer and the drive. Set the scsi-id of the drive
   to 0 and reboot.

Done! 

I didn't attempt to setup my internal drive as 'swapdrive' because
someone told me that I can no longer boot from the internal drive
and if I do the symlinks in the internal drive would be messed up. 
Does anyone know how to use the internal drive as swapdrive and still
be able to boot from it (in case the external crash)? Thanks!
