I have been trying to get OS2 v 1.2 up and running an a 386SX clone
machine. The loader and kernal seem to run just fine. The problems
I'm having are with my ATI VGA-16 Bios V3m-1.06 and a mono card.

1. On booting up the system, it will not load the PMSHELL.EXE
   reliably. Sometimes it gets past loading the mouse driver 
   and COM02.SYS etc., then When PM tries to load I get TWO BEEPS.
   shortly there after It  freezes up and The FAT red button comes
   into action. - My work around - I map the PROTOSHELL statement
   to CMD.EXE and Load either SHELL OR PMSHELL BY hand. 

2. When I do finally get the PM up and running if I run CodeView,
   (/2 etc...), I get the top 6 lines of the screen on the mono card
   (I.E. Display) and maybe 3 at the bottom. The middle is blanked out
   or has random characters. My conclusion is that some one in OS/2 land
   is using the mem. 

3. If I can not successfully start PM, I have through experimentation
   determined that removing the file OS2.INI in the OS2 directory 
   will cause PM to rebuild it, but all of my Groups and Settings are
   nuked. So I rebuild it and it works for a while. But when Mars and
   venus get aligned, I'm back where I started.(i.e. no apparent reason).
4. CHCP gives me the following message:
   there is no codepage prepared for this display adapter.
   
Summary:

Has anyone out there successfully got the  ATI VGA-16 and a mono card to
work successfully together under 1.2. How do you Keep PM up and running.

?????????

P.S. 
The ATI support personnel told me this gem:

You have to set the ATI board up for 8-bit bus use if there is a mono board
in the system. Why ? A sixteen bit board cannot share a data path with an
8 bit board.

Hmmm.....

Well why can I run Codeview for windows on the mono board with no problems?

and      

From what I remember B000:0000 has noth'n  to do whith A000:0000 and beyond.
(i.e. the VGA memory mapping in VGA mode could care less about the mono
address space.).

Thanks
