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in & out Make copies of disk 3 by using dd if=/dev/at0 of=/dev/at1 # this results in 2400 records in & out I had originally made a set of disks using /dev/fd0 and /dev/fd1 for all 3.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.
