Int 10 Fn 1001  - Video - Set Border (overscan) Color (pcjr,tandy,ega,vga  [V]

   AX = 1001h
   BH = border color (00h-3Fh)

Return: nothing
BUG:   the original IBM VGA BIOS incorrectly updates the parameter save area
     and places the border color at offset 11h of the palette table
     rather than offset 10h

Note:  under UltraVision, the palette locking status (see AX=CD01h)
     determines the outcome
