 First, the problem:

 I've killed OS/2 somehow.  It now boots up and gives only a black screen.

I'm new to OS/2 as of 4 days ago, so bear with me.  My experience is mainly
with DOS, Unix, Amiga, CP/M, etc.

 My equipment:
 IBM PS/Valuepoint 486DX/33,  with OS/2 v2.0.1 preinstalled
 PS/VP 6319 monitor, 15" flatscreen multisync
 
 I made a backup of the preinstalled system, and repartitioned my disk
with:
 60 Meg HPFS for OS/2
 20 Meg FAT for DOS/Windows boot
 120 Meg FAT for programs/data

 The OS/2 and DOS partitions are primary.  I couldn't make OS/2 a logical
partition because the preinstalled system only wants to be drive C:.
But I figured this would work nice, and give me a path back to DOS.

 What I did:
 I decided to try playing with 1024x768 screen modes.  I went thru the
Welcome window and configuration setup to configure the 1024x768 mode for
the desktop.  Did a shutdown, and it worked ok.

 But the screen was flickering pretty bad.  I thought this was kind of
stupid, as this monitor was supposed to be able to do non-interlace.

 So I went back to 800x600 resolution.  No flicker.

 So I start reading the FAQ.  Don't find much in there about this, but the
section on SVGA under DOS interests me.

 It says I can do this 'SVGA ON' command to setup DOS for SVGA.  And then it
mentions about setting refresh rates prior to that.  So I pulled out the VGA
utilities disk that came with the computer.  It's a Tseng ET4000 chipset in
there, and looking thru the manual it says to type 'VMODE 72M' to set it up
for 72 Hz refreshed 1024x768 mode.

 I ran a DOS program that uses 1024x768 resolution(Atlas GIS), and by golly
it did work! No flicker...

 So I did VMODE 72M, and VMODE 72H, SVGA ON, EXIT and Shutdown the system.

 Booted back up into OS/2, worked ok.

 Went thru the Welcome folder's system configuration and set it up for
1024x768 mode. Shutdown, rebooted and...

 Nothing, it's black.  The disk light comes on when I do things like
Ctrl-ESC, hit mouse buttons, etc.  Just no display.

 I've tried renaming the file 'SVGADATA.PMI' which was created by SVGA ON to
something else, but the machine locks up completely when I do that.

 So I have a couple of questions, if anyone can answer them:

 1. How do I remedy this situation?  If I have to, I will reinstall the
OS/2 system, that's why I set it all up on a seperate partition.

 2. How do I get OS/2 to use a 70 Hz non-interlaced 1024x768 on the
desktop? It does 60 Hz by default and flickers badly.

 I'll summarize any responses.

Thanks for any help.
