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.

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

Changes for release 43.165:

- The return code for the interrupt server was not right and did not
indicate that a card interrupt was actually not present, blocking other
interrupts on the same handler chain.

- The BltPattern drawing primitive did not handle the INVERSVID draw
mode correctly.

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

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.
