  Interrupt:   1Dh
 
  Title:       Pointer to Video Parameter Table
 
  Description:                                               [MDA] [CGA]
 
     Vector points to a table of data used by BIOS Int 10h routine to
     initialize CRT controller during Set Video Mode operation
     (Function 00h). Useful only for MDA and CGA, but maintained by
     other video systems for compatibility.
 
     Vector does not point to a valid routine and must not be called
     with an INT instruction. Access this with Int 21h Function 35h
     (Get Interrupt Vector).
