Subject: Re: new installation of djgpp


| I have just recently obtained djgpp and installed it on my pc.  I also 
| obtained the libgrx graphics and installed them on my pc.  I installed 
| these according to the directions and checked this several times and on 
| several pcs.  When I compile any of the graphics test codes with djgpp or 
| libgrx they compile successfully.  However, they don't appear to send 
| graphics to my screen and often crash the computer.  I figured this was a 
| problem with the graphics driver specification.  I have a Trident 8900C 
| chip with 1M.  I have tried setting the driver in the GO32 variable to 
| all of the trident drivers, and I have tried using all combinations 
| options to this variable.  I have also tried using the plain EGA, and VGA 
| drivers with various options.  I have also not set the go32 environmental 
| variable.  I have also done similar attempts on other machines with other 
| graphics drivers.  I feel that I am missing something fundamental.  Has 
| anyone had similar experiences or can anyone offer any sugestions.

I don't know if this will help you but ... I have a Trident 8900C and use 
libgrx. My GO32 environment variable is:

GO32=nodpmi driver c:/<my path>/tr8900.grn gh 600 gw 800 th 25 tw 80 nc 256

This works fine for me. Note the use of `nodpmi' in my case because I use
386MAX. 

Hope this helps,
