Int 2F Fn C000  - VGAsave V1.93 - Installation Check                       [V]

   AX = C000h

Return: AL = FFh if installed
       BX = segment of resident code
Program: VGAsave is a freeware VGA-specific, mouse-aware screenblanker by Bill
     Javurek

Note:  VGAsave may use any AH value from C0h through FFh; the transient
     portion of VGAsave compares the first 38 bytes of the resident code
     (addressed through BX) against its own copy of the resident code to
     complete the installation check
