(S)VGA TRICKS - PART 1
--------------------------------------------------------------------------
This little text was originally placed in the Imphobia MAG 12. I've added
some little things and I want it to be available for every programmers and
not only sceners. I hope you'll like it and I encourage you to D/L the
Imphobia MAGs (great MAG, Darky !!!) available on ftp.cdrom.com /pub/demos
and ftp.arosnet.se to read other amazing programming tricks and more...

Well, i just want to speak here about tricking the VGA/SVGA adapter ...
95% of the VLB video cards are SVGA and support at least 15 bits mode (32k).
100% of the PCI video cards support 32k, 65k, and 16M colors (in 24 or 32
bits), and support FLAT linear mode. I don't know any VLB/PCI video cards with
less than 1M ram. So since the scene has moved on 486 VLB more than 2 years
ago, why didn't they use the features of the VLB-videos in demos ???
I'll speak here about 12 points:
(1) History (5) S3 805 bug (9) 50Hz/60Hz
(2) 320x200x256 > 1 page (6) UNIVBE "safe" modes (10) 320x256
(3) 320x200 Hicolor (7) No Mode-X with SVGA (11) 120Hz
(4) S3 Trio/Vision limitations (8) DRAMs speed up (12) BitBLT intro
==========
1. HISTORY
==========
As far as i know, the first full SVGA demo i've seen is the demo presented
by Realtech at ASM 95. But, if i remember, the rulez of the ASM 95 party was
that the demo had to run on a 100% VGA display too. Some times before, some
groups like Impact Studios and their "Project Angel" demo implemented stuffs
using the SVGA properties (i.e. 320x200x256 chained and banked). Even Complex
have used some tricks in their famous demo "Dope" to reduce wait states on
Cirrus Logic video cards. The problem of custom SVGA routs is obviously the
incompatibility with future generations of video cards and that is probably
why only a few guyz have attempted to play with SVGA.
But since february 1995, a new weapon is born which is called UNIVBE 5.1.
This nice VBE driver developped by Scitech offers you a 100% VBE 2.0 interface
(giving you an acces to FLAT linear addressing), and last but not least,
plenty of new video modes (the one they can manage with your video cards), in
particular 320x200x65k and 320x200x256 multipages. When i got the beta release
in early february 95, I was just developping my own way to handle the SVGA,
but i had some probs to get my code working on all video cards.
With the release of UniVBE 5.1, i immediatly thought that everyone should
use it in demos, to get really high quality gfx, in particular in 3D demos.
But since most parties were forcing people to use VGA, i think that no many
groups were ready to adopt it, and so we've seen many fake-18 bits modes
and other cheats to make the illusion, and blah blah ...
The opportunity to launch UniVBE 5.1 in the demo scene was Wired 95, because
some members of my crew (not me) were in the organizing staff, and because i
really believed in Wired. I've done all my possible to make them allow SVGA
support (specially Hicolor and even True Color) with UniVBE 5.1... and they
have done it. At Wired 95, i think that 2 demos used SVGA features:
1) Realtech's "Countdown" which supports VBE 2.0 FLAT linear, video modes from
320x100 up to 1600x1200 !!!! (but still in 256 colors), and even S3 BitBLT
support (however some probs on S3-805 ;-) ).
2) Our demo "Hurtless", which also supports VBE 2.00 (or 1.2), and 640x200 &
320x200 32k colors, 320x200x256 16 pages (like "Project Angel"), with
UniVBE 5.1 if present, or with custom routines if not present, BitBLT for
Cirrus Logic, Advanced Logic, S3, Primus, ... ; DRAM speed up for S3 and
Cirrus Logic.
Then, during november 95, the demo A-Colors came, which supports 32k and 16M
(!!) colors. At The Party 95, Realtech used 65K colors in their demo
"6th sense", really nice, (if you can run it !!!). And more recently, Complex
used 65K colors in their intro "Supermax" presented at The Gathering 96.
But in fact UniVBE 5.1 has some limitations that we must consider if we want
to run our code on every Video cards. In newsgroups, i've yet read some mails
speaking about problems to run such demos (like "Why doesn't Supermax run on
my S3 Trio", ...). In fact some video modes are "safe" and some others "not",
and even the new UniVBE 5.2 will not change that ... but i'll speak about that
in the next lines ...
====================================================================
2. HOW TO DO 320x200x256 WITH MORE THAN 1 PAGE, WITHOUT UNIVBE 5.1 ?
====================================================================
The following tricks may be used if UniVBE isn't present.
There are 3 ways:
a) Init mode 13h and enable access to bank registers
You have to do a specific code to enable the bank registers, and then use
a specific code to switch the banks. If you want a nice collection of
specific codes, I suggest you to D/L vgadoc4b.zip (see in the beginning).
This is the only way to get multipage on a S3, for example, because method
'b' doesn't work on such card.
b) Set 640x??? mode en then half the horizontal values
I think this is the best method, because you start from a SVGA mode where
all the bank registers are enabled. So you don't have to do a specific code
to enable the banks and you can even use VESA calls to switch the banks !!!
Moreover, this is the only solution if you want to get 320x200 multipages
on Cirrus Logic video cards. I think this works on 70% of the VGAs.

;---------------------------------------------
c) enable a 128k page in a0000-bffff to get 2 pages
This doesn't work on every cards. It works on the Cirrus Logic and possibly
on some Tsengs (?), and ... I suggest you to do a test. Make sure that you
don't have EMM or QEMM using the space between b0000 and bffff (you can
test it by checking if there is RAM in this zone before enabling the 128k).
On Cirrus Logic, it only works in SVGA modes :-(.
mov dx,3ceh ; active 128k adressing
mov al,06
out dx,al
inc dl
in al,dx ; rem: dx=3cf/3ce=6
and al,NOT(1100y) ; Video RAM should be mapped on a000-b7ff
out dx,al
But even with these 3 methods, there are still video cards on which it is
impossible to get a full working multipage mode (ie. S3 805)
===================================================
3. HOW TO DO 320x200 HICOLOR WITHOUT UniVBE 5.1 ???
===================================================
The following trick may be used if UniVBE is not present.
On most SVGA HiColor cards, you can obtain 320x200 HiColor from a
640x480x256 or 640x400x256 mode (VESA 101h and 100h respectively). This is
because most HiColor DACs are inspired from early Sierra DAC (which combines
2 consecutive bytes to form a color), but they don't use the same value to
enter in HiColor. So we also need 640x480 Hicolor, just to dump the DAC value
in this mode. 640x480 Hicolor should be supported by every BIOS because it's
a Windows mode ;-).
For example, if your video card has a Sierra like DAC, you can do 320x200
hicolor using the following method:
; SIERRA DAC like method (works on 75% of the cards) !!!
mov ax,4f01h
mov bx,110h ; set VESA 640x480x32K colors (works on VESA 1.2)
int 10h ; (60 Hz)
; remove tho following lines
; if you want a FLAT linear mode (need a VESA 2.00)
;

;---------------------------------------------
Notes:
- If you start from 640x400, you'll get a 320x200x32K 70Hz, but the problem
is that 640x400x256 is not present on every video cards (ie. Cirrus Logic,
...). However 640x400x256 is done on every video cards by UniVBE 5.1, but in
this case, if 320x200x32K is possible, UniVBE will provide it to you and it
is not necessary to do it by hand !!!
- You can switch in a 65K mode in a similar manner.
- You can get 320x350 or multiples if instead of the values dumped from Mode
13h in ***, you use the values of the EGA mode 640x350... (the 350 scanlines
V-clock is A0h)
- You can call the "setdac15_" procedure of VGADOC4 to switch the DAC and to
avoid the Sierra FLIP-FLOP. setdac15_, (or setdac16_, setdac24_) is more
general, it supports BrookTree DAC, ... and even S3 Trio (but in this case,
the screen becomes totally crasy ;-) ). This works on 85% of the cards.
If your application is designed to run on 486s, I suggest you use a 32K
display (becoz there are VLB and ISA boards supporting only 15bits/pix) with
both LINEAR and BANKED adressing support. If it's designed for Pentium, 65K
LINEAR is preferable ( I don't think there exists a PCI card without 65K and
LINEAR adressing support).
=====================================
4. S3 TRIO/VISION 864/964 LIMITATIONS
=====================================
The new S3 family uses a new integrated RAMDAC wich is not compatible with
the old "Sierra"-like DAC wich was on S3-805, ...
This new RAMDAC seems not to be able to handle 320x200 in Hicolor/Truecolor
mode, so you have to make a version of your application runing in a mode
derivated from 640x480 Hicolor to be certain.
S3 Trios are only able to display 16.7M colors with 32 bits/pix and not
24 bits/pix !!! This require a 2M adapter, so maybe 65K is to preferable to
16.7M.
We can't ignore S3 Trios because they are one of the best-selled videocards.
=============================================
5. S3 805 PROBLEMS WITH 320x200x256 MULTIPAGE
=============================================
In particular the mode offered by UniVBE 5.1.. This mode is obtained by
enabling banking in mode 13h. This works on all S3, but on the 805 series
(many S3 VLBs) and may be on the 911 (i haven't tested), the pair and impair
rows are inverted ! Which is far to be aesthetic !!! So regular mode 13h has
still a reason to exist !!!
=======================================
6: THE UniVBE MODES THAT ARE "SAFE" !!!
=======================================
The UNIVBE modes that you will get on every 1M True colors VLB/PCI cards are
(I don't consider modes above 640x480) :
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
640x480x256 (60Hz) 640x480x32k (60Hz) 640x480x65k (60Hz)
640x400x256 (70Hz) 640x400x32k (70Hz) 640x480x65k (70Hz)
640x350x256 (70Hz) 640x350x32k (70Hz) 640x480x65k (70Hz)
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
But you can alter the vertical ratio without problem, simply by ajusting the
character height:
mov dx,3d4h
mov al,9
out dx,al
inc dl
in al,dx
and al, NOT(31)
or al, height
out dx,al
with 0 <= height <= 31
Example: if you set 640x480x256, you have
with height = 0 : 640x480x256 -> /1
= 1 : 640x240x256 -> /2
= 2 : 640x160x256 -> /3
= ...
Note: However the 800x600 and 1024x768 modes are safe, they can have problems
with a video projector, so use them as a bonus.
====================
7: NO X-MODE IN SVGA
====================
I've read some articles on the Net and in the PCGPE, I think, talking about
using Mode X with a 640x400x256 or 640x240x256 display. The idea is not bad ,
because with conventionnal Mode X, you can address 256k of Video RAM without
banking. So Mode X should offer a way to use such videos modes without banking
on every video cards (even old ISA).
But... this is true if you suppose that your SVGA card works like a VGA card
in such modes ... and that is NOT true !!! New generations of cards are no
more Mode X compatible in Hi-Res !!! If you try such code on S3, for example,
you will get some surprises.
===========================
8: DRAMs SPEED UP / BOOSTER
===========================
a) You can obtain better performance with a Cirrus Logic 542x, if you add
these lines in your code (even with Mode X !) :
--------------------------------------------------------------------------
mov dx,3c4h
mov al,0fh
out dx,al
inc dl
in al,dx
and al,NOT(8+16+32)
or al,(6 SHL 3) ; 32 bit mode + CRT FIFO depth control
out dx,al
dec dl
mov al,16h
out dx,al
inc dl
in al,dx
and al,15
or al,(0 SHL 4)+(2 SHL 6) ; delay for mem Write I/O
out dx,al
It basically reduces the DRAMs wait states. I think that Complex used a
similar trick in "Dope". Normally there are no probs, but it's always a good
idea to allow the user to disable the booster.
b) S3 cards can be accelerated by the following code :
---------------------------------------------------
; code hacked from S3SPEEDUP / meschede
; available on ftp.uni-muenster.de /pub/meschede/...

If you want to boost an SVGA mode banked, just type:
call MAP_A000h
call FAST_WRITE_BUFFER_ON
If you want to boost an SVGA mode FLAT linear, just type:
call FAST_WRITE_BUFFER_ON
====================================
9: 320x200x256 50Hz AND 60Hz CHAINED
====================================
If you want 50Hz chained mode (why ???), as in the demo "Xtal" by Complex,
just type this code:
mov ax,13h
int 10h ; regular mode 13h chained
mov dx,3c2h ; misc output
mov al,0e3h ; clock
out dx,al
mov dx,3d4h
mov ax,07006h ; Vertical Total
out dx,ax
mov ax,03E07h ; Overflow
out dx,ax
mov ax,0F310h ; Vertical start retrace
out dx,ax
mov ax,08C11h ; Vertical end retrace
out dx,ax
mov ax,08F12h ; Vertical display enable end
out dx,ax
mov ax,0E715h ; Vertical blank start
out dx,ax
mov ax,00416h ; Vertical blank end
out dx,ax
It works on every VGA !!! Maybe some probs with VGA-2-RGB converters or
projectors...
The 320x200x256 60Hz version is normally more adapted for RGB projector :
mov ax,13h
int 10h ; regular mode 13h chained
mov dx,3c2h ; misc output
mov al,0e3h ; clock
out dx,al
mov dx,3d4h
mov ax,0B006h ; Vertical Total
out dx,ax
mov ax,03E07h ; Overflow
out dx,ax
mov ax,0C310h ; Vertical start retrace
out dx,ax
mov ax,08C11h ; Vertical end retrace
out dx,ax
mov ax,08F12h ; Vertical display enable end
out dx,ax
mov ax,0E715h ; Vertical blank start
out dx,ax
mov ax,00416h ; Vertical blank end
out dx,ax
======================
10) 320x256x256 60Hz X
======================
Or the "Amiga PAL mode" ;-), like in "Ninja II" by Melon & Scoop, just type
this code:
mov ax,13h
int 10h ; regular mode 13h chained
mov dx,3c4h
mov ax,0604h
out dx,ax ; unchain
mov dx,3c2h ; misc output
mov al,0e3h ; clock
out dx,al
mov dx,3d4h
mov ax,0D006h ; Vertical Total
out dx,ax
mov ax,03E07h ; Overflow
out dx,ax
mov ax,0FF10h ; Vertical start retrace
out dx,ax
mov ax,0FF11h ; Vertical end retrace
out dx,ax
mov ax,0FF12h ; Vertical display enable end
out dx,ax
mov ax,00014h ; for mode X
out dx,ax
mov ax,0FF15h ; Vertical blank start
out dx,ax
mov ax,00616h ; Vertical blank end
out dx,ax
mov ax,0e317h ; for mode X
out dx,ax
This mode works like Mode-X and it works on every VGA !!! Normally, it will
pass on every RGB converter/projector ...
===========================================
11) 320x200x256 120Hz (16 BITS MODE ON VGA)
===========================================
The mode used by Tran in his famous demos "Ambiance" and "Luminati" :
mov ax,13h
int 10h ; regular mode 13h chained
mov dx,3c4h
mov ax,0604h
out dx,ax ; unchain
mov dx,3d4h
mov ax,00506h ; Vertical Total
out dx,ax
mov ax,01107h ; Overflow
out dx,ax
mov ax,0E710h ; Vertical start retrace
out dx,ax
mov ax,00011h ; Vertical end retrace
out dx,ax
mov ax,0C712h ; Vertical display enable end
out dx,ax
mov ax,00014h ; for mode X

It works in mode X in order to get 4 pages.
- You just have to flip between 2 screens, one containing the first 8 bits and
the other containing the other 8 bits of the RGB colors.

- You can also flip between two traditionnal 256 colors screens to get some
transparency !
The only problem with this mode is that it is totally incompatible with RGB
projectors used in demos parties. So, this kind of modes is to be used in
BBStros, or if you want to use it in a party, you have to do a regular version
for RGB projector (using true HiColor, or using fake 18 bits -like Orange, for
example-, ...).
It works on every VGA !!!!

12) Hardware BitBLT
===================
Well, I can't develop the way to do Hardware BitBLT in this article, but
i'll try to do it in Part II. Just some words:
In fact, Hardware BitBLT is really (and only?) usefull to clear a screen or
to copy a background in SVGA modes (at least if you don't want to rebuild your
code for each BitBLT processor). You can really improve your code if you use a
really high definition like 640x480 or 800x600... For my part, i used it in
320x200x32K to scroll a background (128k to restore), and I really got 5 more
frames/sec on a 486 DX40, using BitBLT.
BitBLTs are stable in SVGAs modes... Don't use it in VGA modes !!! Don't use
it in the 320x200x256 multipages provided by UniVBE 5.1, and don't use it in
24 bits modes ( 3 BYTES / colors ) (BitBLT gets a bit confused when it has to
work with 3 bytes/col, in particular on S3).

Greets to all my friends, all TFL-TDV members, all kewl guyz of the scene I
got a nice chat with, and all guyz who will greet me and my group in the
future ;-)
I especially thanx Bismarck/TFL-TDV and Access/Antares for accepting SVGA at
Wired 95, Wizard/Imphobia and Walken/Impact Studios for some inspirations.
