The Voodoo.card driver is a P96 driver implementation for the Voodoo

2,3,4-5 3dfx graphic cards for PCI bridge boards. This driver adds

support for the latest P96 versions and as such offers panning, screen

dragging, mode mixing and overlay windows (also called

Picture-in-Picture, "PiP").

Due to limitations of the hardware, only 16 bit Hi-color

screen modes can dragged, but the video modes of the background

screen are not limited, i.e. one can drag Hi-color screens

to reveal a chunky or true-color screen in the background. As for

P96 screens in general, the foreground screen cannot be dragged

if there is no background, or the foreground screen uses panning.

The driver supports all features the card offers: Accelerated

rectangle filling, rectangle inversion, copying, line drawing, and

pattern fill, also conversion from planar to chunky is accelerated.

The card also offers a hardware sprite used as mouse pointer.

At this time, the driver is not yet tested on the Voodoo 2

and Voodoo 4/5, thus feedback is appreciated.

This driver is based on OpenPCI, found at:

http://bvernoux.free.fr/DevPCI.php

unfortunately not available on Aminet. As OpenPCI does not

seem to formulate license conditions, it cannot be included

in this distribution.

----------------------------------------------------------------------

This driver is provided to the Amiga community as contribution

and gift in return to the A4000 I had the honor to receive.

Thanks a lot, folks! Here is something in return.

----------------------------------------------------------------------

Installation:

- Download OpenPCI from

http://bvernoux.free.fr/openpci2.1_beta4_081009.zip

unzip and copy the openpci.library to LIBS: if not yet

already present there.

- Copy Voodoo.card to LIBS:Picasso96/

- If not already present in the system, install P96 with the

included installer, but do not select any graphics card.

The P96 installer will then place a file "Generic" in

DEVS:Monitors.

- Take this, or any other P96 monitor icon, and edit its

tool types with the workbench. Add or modify the following

tool type:

BOARDTYPE=Voodoo

- Rename the icon to Voodoo.

- Reboot the system, and start either Picasso96Mode or

P96Prefs (preferred).

- For P96Prefs, select the Voodoo monitor and press on

"Add Default Modes", then edit the modes to your liking.

In particular, for low resolution modes, it may be necessary

to adjust the horizontal or vertical frame size (the first

two numbers on the right-hand side of the window) to

adjust the horizontal and vertical refresh rates to match

the requirements of the monitor. P96Prefs 47.15 and above

perform these steps automatically when creating modes for

the VA2000.

- For the Picasso96Mode program, you need to create the

desired modes manually.

- Note that the modes of older Voodoo drivers cannot be used

directly as its drivers indicate the board type incorrectly.

They are associated to the Prometheus board (sic!). To

reuse such modes, select them in P96Prefs, use "Copy" from

the "Edit" menu, and "Paste" them into the new settings.

The following additional tool types are recognized by the

driver and can be added to the driver icon either by the

workbench:

INTERRUPT=<yes|no>

Enables or disables usage of the vertical blank interrupt

of the board. Not all PCI bridge boards may support this.

If present, screen operations can be synchronized to the

screen, avoiding tearing.

MEMORYCLOCK=<clock in Mhz>

allows to select the memory clock in Mhz. Useful values

are between 100 and 220. Generally, there is no need to

play with this tooltype as the correct memory clock is

taken from the VESA Bios of the card.

DISPLAYCHAIN=<yes|no>

Enables (with "yes") or disables (with "no") support for

switching monitors. The card itself does not offer a

VGA switch, but if you connect the VGA output of the

card with one input of your monitor, and the native

Amiga output with another input, the inactive output

will be disabled, allowing smart monitors to switch

between the outputs. This may be used as a poor-men's'

VGA switch.
