[net.micro.pc] PC-DOS 2.0 vs MS-DOS 2.0

michael@rlgvax.UUCP (Michael Connick) (08/10/83)

First off, let me state that I own a Victor 9000, not a PC. However due to the
similarity of the two machines hardware and software I have become an avid
reader of this newsgroup and the various PC mags.

I have been following with great interest the various discussions and flames
associated with PC-DOS 2.0. My impression is that IBM has really done a
disasterously bad job on this operating system and I can't understand why!

The consensus of opinion seems to be that IBM was forced to quickly release 2.0
because "the XT's hard disk wasn't supported by 1.0". How can that be true???
I have had a Victor 9000 with a 10 meg hard disk for many months operating with
MS-DOS 1.25a. This is a version of 1.0 designed to support a hard disk
environment. The additional features added to the standard 1.0 version consist
of a series of utilities allowing formating and partitioning of the hard disk
into 1-n MS-DOS volumes and a configuration utility with a series of default
partitioning schemes. The hard disk can be configured as the boot device. I can
see no reason why this version of MS-DOS couldn't have been used on the XT.

This week I received an alpha copy of MS-DOS 2.0 for the Victor. Having read
all the articles on PC-DOS 2.0 I was prepared to start getting used to using
"\" in path definitions. Wrong!!! MS-DOS 2.0 as it comes from Microsoft uses
the normal "/" character in path definitions. Why did IBM use the backslash in
their implementation? The Victor documentation also indicates that all bugs
that were identified in PC-DOS 2.0, except for some problems with SORT, have
been corrected. (This is internal Victor documentation which I received as a
result of my consulting relationship with Victor.) This documentation also
stated that the stability of 2.0 is now good enough for release of the
operating system to Victor in-house users and selected software developers. If
Victor is only now allowing restricted distribution of the operating system,
how could IBM have previously released it to their unsuspecting customers? Why
not start with MS-DOS 1.25a for the initial release on the XT?

Since I just recevied MS-DOS 2.0 two days ago, I have not had time to gain much
experience with it. A quick reading of the manual suggests to me that there may
be some other differences between MS-DOS 2.0 and PC-DOS 2.0 other the "\" and
"/" usage. If there is any interest on the net, I will post these differences
as I discover them. I haven't even had a chance to review the "Programmer's
Reference Manual" (delivered, interestingly enough, on a floppy).

In conclusion, I am baffled by IBM's release of PC-DOS 2.0 and am interested in
hearing any comments from netland on my posting.

I have been following all the discussions about DOS 2.0
on net news and keep wondering if I am using the same
awful piece of software. I have been using DOS 2.0
(from IBM) for the last 5 months and have not had any
problems with it. I have used several software packages
(VisiCalc, KnowledgeMan, Async Comm Support,...) and
they all work just as well (if not better) than with
DOS 1.1.

I have written several assembly language routines to
allow C system calls (read, write, lseek, open, close)
to be done from PASCAL so I can make use of the tree
structured directories and they work just fine. Now I
am sure you can find problems with it (and I have), but
what is the big deal?
