[comp.windows.ms] XGA

altman@sbcs.sunysb.edu (Jeff Altman) (04/19/91)

Just got an XGA for my 55sx.  Took 7 weeks for delivery.
The 1024x768x256 is great.  And extremely fast.  I have fewer
problems with text file scrolling at 19200 now that the video 
driver can actually keep up with in coming text.

But anyway, I have a new problem that I have been unable to
decifer (sp?).  I am no longer able to Run non-windows applications.
I get a message from Program Manager :
	"Unexpected DOS error: 11."

This happens in Enhanced Mode.  Trying to even load in Standard mode
causes a reboot.  Real mode loads sometimes.  

I removed QEMM, Hyperdisk, ATM, 4DOS, and everything else that was being
loaded before starting Windows.  No difference.

By editing SYSTEM.INI by hand and restoring the settings for the standard
VGA driver everything works fine.

Any ideas?  Anyone else have an XGA working under Windows?  
What does the error mean?  I looked at the Result Code from WinExec 
thinking that the result code was the error message.  But an 11 from
WinExec just means that (1) its not a windows app, or (2) the EXE 
header is corrupt.

Neither of which makes much sense.

Thanks for any assistance or insites you might be able to provide.

After spending 5 hours switching back and forth between the Windows
Disks and XGA Driver Diskettes; using Setup; VGA and XGA modes, etc.
I started to compare the files with the same name from the IBM disks
and the Windows disks.  As it turns out, IBM just copied the files 
directly from the Windows diskettes.

Now the Windows diskettes contain files which are compressed.  The IBM
generated files were not compressed.  The Setup program expects OEM
driver files to not be compressed.  Therefore, it installed the compressed
files assuming they weren't compressed and said "I'm done!".  But 
of course, it didn't work.

The solution is to use the Expand program on each of the installed files.
Then Enhanced Mode works.

This problem is rather different.  There is a conflict between QEMM 5.1x
and Windows 3.0a (at least) when using the XGA.  After spending 100 minutes
on the phone with one of the most helpful and intelligent Tech Support people
that I have ever had the pleasure of asking assistance from, Quarterdeck 
decided that this was a problem that they will have to perform research on
and find a fix for.  I hope to be able to post an announcement of the patch
in a week or two.  Quarterdeck Tech Support is GREAT!
