As you may know, IBM has announced a multitasking operating system
called OS/2 to be available in early '88. It will be capable of
running old PC/MS-DOS programs in "real" mode. Also, it will be
capable of running multiple "protected" mode programs not
yet widely availble.
I have an application that needs a multitasking MS-DOS environment.
Basically, I want to remotely run a accounting package (via terminal)
and locally be able to run editors, spell checkers etc. OS/2 gives me
this capability IF IT RUNS ON A AT&T 6300+.
In an effort to find out if ANY IBM operating system runs on the 6300+,
I installed IBM's DOS 3.2 last nite. My initial observations are:
-3.2 couldn't read the C: drive that already had a copy of
ATT MS-DOS 3.1 on it. After some effort, I was able to
reformat the C: drive (loosing everything on it) and
copy DOS 3.2 to it.
Then I ran norton on the drive to see what 3.2 did to it.
It seems that they formatted it with many more clusters than
what AT&T 3.1 had used. That is why they couldn't read the old
format. (about 3000 with 3.1 vs 10000 with 3.2)
-3.2 couldn't find my AT&T battery powered clock. It always came
up with the date set to 1-1-1980 at 0:0 or something close to this.
-when scrolling more then a half of screen of text, in a color mode
(white foreground, blue background), the upper half of the screen
flickered until the scrolling stopped.
No other problems were noticeable. I am still playing with it though.
Has anyone tried this sort of experiment? Are there more problems lurking
that I haven't found yet AND does anyone have a solution for the above
noted problems short of returning to 3.1?
Thanks,

AT&T MS-DOS formats hard disks with 8K size clusters where as
IBM PC-DOS 3.x uses 2K cluster. SO if you want to use PC-DOS 3.x on
an AT&T machine you may have to reformat the hard disk.
There is a public domain program named CLOCKDEV.sys which fixes the
clock and calendar problem. If there is enough interest, I will post the
program.
