/**********************************************************************
VIDTYPE.C -- detects video card type (and monitor type, but only for
informational purposes), and sets an errrorlevel based on the video card
type detected. Use in a DOS Batch file to load a specific driver, perhaps
on a LAN with mixed video configs.

This implementation was written using Quick C 2.5. Compile it however
you want, but don't forget to include the graphics.lib in your link command
sample compile and link:
qcl /c /Ox vidtype.c
qlink vidtype,,,graphics.lib

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
