Arrgh!

Not only are we rehashing the question of "Is Windows 3.1 a operating 
system" but we have bad information about OS/2 to boot!

Shulman (author of "Unauthorized Windows") says that Windows 95 is just 
Windows-386 plus DOS 7.0. In fact, Novell DOS 7.0 already has 32 bit 
drivers as do memory management packages such as Netroom. 

So, you could take MS-DOS 5.0, add Netroom, and add a pretty new (but not 
pretty good) GUI shell, add a further munging of the overextended FAT 
file system.. AND.. you have Windows-95.

YOU decide if that is a whole new 32 bit operating system..

As for OS/2, THERE IS NO DOS SHIPPED WITHIN ANY OS/2 PACKAGE NOR DOES 
OS/2 RUN OVER DOS!

The command syntax of a OS/2 shell session is pretty much identical to 
MS-DOS 5.0 with some commands missing (like MEM) and new commands added 
(like START). It is not DOS.

"START" incedently allows you to start another process which runs 
independently of your current OS/2 session (e.g. START CHECKDSK /F E:). 
This is how your multitask under OS/2 without the WPS (Work Place Shell).

When your run a DOS session from OS/2, you are still not running DOS. You 
are running an OS/2 session with added drivers which cause it to emulate 
a DOS real mode session. This emulation is so good that I have only found 
1 program (FXLINK from DOS 6.0) not able to run in this emulated DOS session.

If you want to get really down and dirty you can run a real mode DOS 
session in a window by placing a bootable DOS disk in drive A: and 
clicking on the "Boot from Drive A:" icon. If you like the results, you 
can make a hard disk image of a bootable disk, and boot from that disk 
image. DOS programs which won't run in a emulated OS/2 DOS session will 
run in a real DOS session.

Oh yes.. I can run DOOM (with the internal speaker) from OS/2 just fine. 
If I want the sound, I just "dual boot" or "multi boot" to my DOS 5.0 
partition and run it there. Just like Windows-95 and it's "single 
application mode".

Of course all my WORK applications under DOS and Windows DO work under
OS/2 and they work better there, than they do under DOS and memory is
never a problem.. 

Launching Windows under OS/2 currently reports 98 Meg of RAM free!

P.S. Check out the current Computer Shopper Tech Section!

Hope this clears up things for you.
