- In general, the mouse drivers do not support SVGA video modes. You can
- still use the driver to report mouse movement, but the pointer will not
- show.
-
- If you are programming in Turbo C or Borland C, you can use the BGI's in
- svgabg52.zip. You can get this at SIMTEL (pd1:<msdos.borlandc>). This
- library has suport for almost all SVGA cards and includes mouse support
- also (some bugs exist however).
