[comp.os.minix] Got it! 3 1/2 in. MINIX 1.3

MRTSI@CUNYVM (Mimi Tausner) (09/08/90)

Some of you have asked me to post a message if I ever figured out how to copy
MINIX 1.3 from 5 1/4" disks onto 3 1/2" disks. Starting with MINIX 1.3 -
the AT version - this worked ...
  (The computer I used has a 5 1/4" drive in 0, and a 3 1/2" drive in 1).

  Use DOS to format 3 high-density 3 1/2" disks
       (At this stage, I am only copying MINIX disks 1, 2, and 3.)
  Boot MINIX 1.3 from the 5 1/4" disks.
  Logon as super-user.
  Copy /usr/bin/dd to /bin and unmount /dev/fd0.
  Make copies of disk 1 and 2 either by using
           dd if=/dev/fd0 of=/dev/fd1  # this results in 720 records in & out
    or     dd if=/dev/at0 of=/dev/at1  # this results in 2400 records in & out

  Make copies of disk 3 by using
           dd if=/dev/at0 of=/dev/at1  # this results in 2400 records in & out



I had originally made a set of disks using /dev/fd0 and /dev/fd1 for all 3.
This resulted in an incomplete copy of disk 3 which caused "strange" symptoms
when I used the set to get into MINIX.

Note that according to AST's message of 6 Sept <7469@start.cs.vu.n1> this
method will have to be changed for MINIX 1.5.  To create a 3 1/2" version of
highly packed disks, you'll probably want to use /dev/PS0 and /dev/PS1.

Special thanks to Ernie Ellenberger who offered suggestions when I originally
complained about the problems I was having with my 3 1/2" disks.
