; Author: Tom Almy, except as noted.
; Card id printout idea by Arend van den Brug.


; Note: I haven't tried all combinations.


; Define both of these TRUE is display type is unknown.
; Otherwise define FALSE what your display isn't.
; Note: If display is neither VGA nor EGA, then this driver won't work, 
;       but the driver will work if you define both of these FALSE. 
;	This is useful for VGA systems that want the 43 line mode to
;	display 50 lines. Note that if VGA is FALSE,, attempting to 
;       set 50 line mode will try to put the display in mode 50, which
;       might just be a disaster!

VGA	equ	TRUE    ; define TRUE for VGA, defining as FALSE eliminates
			; 50 line mode code. (43 line mode will run with 50
			; lines like older nansi and nnansi drivers
EGA	equ	TRUE	; define TRUE for EGA for best results on EGA.
			; defining as FALSE eliminates 43 line cursor fix code



; If you also want NNANSI to work with a monochrome card ("double headed")
; define MONO to be true. Otherwise define as false since this makes the
; driver larger. Note monochrome operation with NNANSI is not spectacular,
; if all you have is a monochrome display, use another ANSI driver.

MONO	equ	FALSE



; VESA Compatibility -- ONLY SET IF YOUR DISPLAY CONTROLLER IS VESA
; COMPATIBLE. This changes some code in the body of NNANSI. You will
; also need to select a display card or use the default.

VESA	equ	FALSE



; Define one of the following true if you have the appropriate
; display card. Otherwise leave them all FALSE.
; Drivers new with this release are marked as NEW

VEGA	equ	FALSE	; Configure for Video-Seven FastWrite VGA, or
			; compatible (such as Tatung VGA (not VGA-16))
PARA480	equ	FALSE	; Paradise EGA 480 (NEW)
PARADISE equ    FALSE	; Paradise VGA 
STBVGA  equ	FALSE	; STB VGA Extra
TVGA16	equ	FALSE	; Tatung VGA-16
EGAWIZ  equ	FALSE	; EGA Wizard Deluxe
ATT600  equ	FALSE	; AT&T VDC600
MAGICVGA equ	FALSE	; MAGIC VGA (CT-8490) Twinhead International (NEW)
			; ps2parms or necparms must loaded for ext. modes
TridentVGA equ  FALSE	; Trident VGA
CHIPS	equ	FALSE	; Chips SVGA (with C&T VGA chip F82C451) (NEW)
TSENG4000 equ   FALSE	; Diamond Speedstar, Orchid Prodesigner II (NEW)
			; (and other TSENG 4000 based, I hope)



; Define the following TRUE if you have an 8088/6 (PC XT or clone), or might 
; want to use the driver with an 8088/6. Define as FALSE for 
; processors >=80186 for best performance and smallest size.

cheap_pc	equ	TRUE	; no fancy instructions if true



; The following options specify certain feature options. These options 
; take space if turned on, but improve performance and/or add features.

key_redef	equ	FALSE	; keyboard redefinition allowed if true
	; If you don't use key redefinition, set at FALSE, since some Trojan 
	; Horse programs take advantage of this. Also it takes space.
init_buf_size	equ	256	; size of keyboard redefinition buffer 
	; and parameter buffer when key_redef TRUE. You may want to change 
	; the size, if you use this feature. Don't make it <100.
quick_char	equ	TRUE ; quick graphic characters in modes 10 and 12
	; quick_char should be "TRUE" unless 
	; you have an incompatible display card.
	; And I don't know of any that are.
fast29		equ	TRUE	; 15 % faster operation (overall)
	;  of int29 calls (costs 100 bytes)
bios_write_tty	equ	TRUE	; take over BIOS write_tty if true
	; NOTE: if bios_write_tty is true, the color rendition of text may 
	; change, but performance will improve and ANSI control codes can 
	; be used. This feature can be enabled/disabled at runtime as
	; long as it is assembled (TRUE)
gbackground	equ	TRUE	; generate non-black graphic backgrounds
	; This option may cause problems for software not expectings its
	; existance. Also you must specify quick_char to use gbackground.
dos4		equ	TRUE	; Answers ANSI.SYS installed (for DOS V4)
	; If you are running a DOS version less than 4.0, you don't need
	; this. If you are running 4.0 or 5.0, you may not care.



; The following options affect initial state. They do not affect the 
; size of the driver.

initbiosw	equ	FALSE	; ANSI write_tty initially on if true
initgc		equ	FALSE	; graphics cursor initially on if true
initfast	equ	FALSE	; initially fast mode if true
	; note- you may have to clear the display (CLS command) before 
	; running some programs, or just before leaving "shell escapes" in
	; some programs.  But it's typically worth the effort.
	; You can disable/enable it with a simple control sequence anyway.
