If you are using Borland's Turbo Pascal 5.0 (4.0 too?) or Turbo C 1.5+ you
can use the Borland Graphics Interface (BGI) to automatically detect what
type of video adapter is present.  I've found the BGI to very time saving.
You can write one program that will work with almost any video adapter /
monitor combination.  You don't even have to bother with writing different
segments of code to deal with different monitors.
