[net.micro.pc] converting from PC-DOS 3.0 to 3.1

ral@pyuxqq.UUCP (R A Levenberg) (07/21/85)

Does anyone know the procedure for bringing up PC-DOS 3.1
when 3.0 is already running on the machine.  I have a PC-AT
with some copy-protected software on the hard disk, so I do not
want to reformat the hard disk.  It's not as simple as just
booting the 3.1 version, and I do want to get 3.1 on the hard disk.

Any ideas?

If I remember the instructions I followed last week, you simply
reboot from the 3.1 DOS floppy, and then say SYS C:.  Naturally
you then copy over all the programs on the floppies to whatever
directory you keep your DOS commands.  I didn't have any problems
at all.  The procedure is different if you are upgrading from a 2.X
system.

Switching from DOS 3.0 to 3.1 is pretty easy, since the operating systems
are about the same size.

1.  Boot up from the 3.1 diskette.

2.  Use the SYS command to transfer the system to your hard disk.

3.  Copy all of the programs you want from the diskette to the hard
disk.  Even programs that seem not to have changed may be version
dependent, so when it doubt, copy them all.

4.  Put the floppy away and reboot from hard disk.

This worked fine for me on many machines.  Takes about 5 minutes.  Note
that you cannot upgrade from 2.x this way because the space reserved for
the operating system on the hard disk isn't enough.

If you have moved DOS utilities into different sub-directories, make
sure that you replace them all.  I have heard many tales of grief of
people upgradeing from 2.0 to 2.1 who were not careful enough and they
trashed up their disks...

Sorry to disagree, but I just upgraded my XT from 2.0 to 3.1.  I suspect
that your problem had to do with trying to SYS 3.1 onto a 2.X floppy.
There is plenty of spare room alocated on the hard disk to sys 3.1 on,
(at least there was on my system, I haven't gone peeking yet to see
what really went on, and am not is a position to do so now.

Unless you need the networking capabilities or an RO atribute that
really works (! see how well it protects a file in dos 2.x !), or 
unless you are on an AT, I suggest you stay with DOS 2.1 -- unless you
have lots of RAM you don't know what to do with :-) .

You were lucky - in general you can't count on there being enough room
free at the start of a 2.x hard disk.  It's probably worth a try, though.
