[comp.sys.att] Running IBM

jrm@cblpe.ATT.COM (John Miller) (06/10/87)

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,
