1.  I have a Cirrus Logic graphics board.........

Cirrus Logic manufactured the graphics controller chip used on your graphics
add-in board or  your computer motherboard.  Companies using our  graphics
chips customize their own hardware and software designs to meet their own
needs. Cirrus Logic can therefore, only assist you with some of your software
questions. We cannot answer questions regarding for example ( memory chip
upgrade information, jumper settings, or installation questions on the
software drivers shipped with your add-in card or motherboard. 
We can assist you with obtaining and installing the reference software
drivers ( the same drivers we send to the manufacturers) if you are unable to
get assistance from your retail manufacturer and answer specific questions
regarding software capabilities.

2.  I am trying to use Warp on my laptop do you have driver support?

The only direct driver support for OS2 Warp is for the CL-GD7543 chipsets.
Laptop chipsets 6XXX work with the standard VGA driver under Warp. There are
no future software development plans for the older laptop chipsets.

3.  What is the Cirrus Logic Bulletin Board number?

(510) 440-9080

4.  Do you have a VESA driver?	
  	
Vesa compatibility for the Desktop chip sets  is built into the video BIOS
(542X Bios 1.20 and above)
 and supports the current VESA 1.2 standard. A Vesa driver should not be
required by the software application.  Vesa compatibility for the Laptop
chipsets is in software and you must load CLVESA.COM (ships with the laptop).
If you are having problems with applications requiring VESA compatibility one
of several scenarios may apply in your case:
	A.  You may have a memory conflict.

Exclude the memory address A000-C7FF from your memory manager.
If you are using Deskview's QEMM386 with stealth you must use the parameter
XST=C000-C7FF.
