Panorama VESA troubleshooting

20090918

Q: I installed Panorama VESA. Traps in display, etc.
A: Disable ACPI.PSD or update to ACPI 2.20,
   reset to IBM GENGRAD, install Panorama VESA again.
   
   
Q: Trap on boot, hang
A: Disable ACPI.PSD or upgrade to ACPI 2.20 or higher
 
 
Q: gradd.log contains errors, GENGRAD is loaded, not VBE2GRAD
A: Read installation instructions again, check CONFIG.SYS again

Q: Trap in PMI1002.DLL during boot to desktop
A: Remove old dlls:
     * Remove PMI1002.DLL (copy it to backup directory)
       (pmixxxx.dll files are extenders for VBE. 1002 - for ATI)
     * If this doesn't help then try remove genpmi.dll, 
     * then ibmgpmi.dll, svgadata.pmi
     
   
Q: Shadow buffer is enabled but it doesn't work (drawing is slow)      
A: * Try upgrade/downgrade motherboard BIOS of the computer.
   * Check x:\vbe2grad.log, It should contain: Write Combine caching enabled 


Q: Video players hang on mouse move
A: Disable comet cursor


Q: DOS, MsgBox: "The system doesn't support the video mode in a window"
A: Try boot VSVGA.SYS with parameters: 
/PCITRAP=08-0F /PCITRAP=10-2F /PCITRAP=E0-F3 /PCITRAP-F8-FB /PCITRAP=100-113

Try them individually and/or all together, and hopefully you'll find
something that works.

Change in CONFIG.SYS:

to
DEVICE=x:\OS2\MDOS\VVGA.SYS
