; This macro is to jump if display is in an EGA/VGA 16 color
; "compatible" mode -- this means one which is a simple extension
; (more rows and/or columns) than modes 10h or 12h. At minimum
; modes 10h and 12h themselves qualify.
; No registers may be altered.
; Byte location "cs:video_mode" is a copy of byte 40:49H.

;gmode_code macro
; this macro is used to tell if display is in graphics
; mode by looking at the byte 40:49H, which is in
; register AL at the start of the macro.
; It is to set location cs:gmode_flag non-zero if in a graphics mode.
; Value of 7 is reserved for the monochrome adapter.
; No registers may be altered.
; *NOTE* users of Paradise and possibly other VGA
; cards will need to modifify this routine because
; Paradise extended character modes set this byte to
; to the value of the mode you selected. Nicer cards
; (Genoa and VEGA, that I know of) leave this byte at
; "3" and all works fine!
