> Bochs supports the emulation of 4 different 3dfx Voodoo Graphics adapter models.
|
|
The Voodoo1 and Voodoo2 models are 3D-only add-on cards and require a VGA
|
|
compatible primary device. The Voodoo Banshee and it's successor Voodoo3 have
|
|
both a VGA core and a 2D/3D core, so no other VGA card is required. The 2D/3D
|
|
cards can be assigned to AGP if the i440BX chipset is selected (slot #5).
|
|
</P
|
|
><P
|
|
> To emulate the Voodoo1 or Voodoo2 device only the "model" parameter of the
|
|
bochsrc option "voodoo" needs to be set. If the vga extension option is set
|
|
to "voodoo" in that case, the primary display adapter is an ISA VGA card.
|
|
</P
|
|
><P
|
|
> For emulating the Voodoo Banshee or Voodoo3 adapter, the vga extension option
|
|
must be set to "voodoo". Using a different primary display adapter and a
|
|
Banshee compatible device with it's VGA interface disabled is not
|
|
implemented yet. Both Banshee and Voodoo3 currently need a specific external
|
|
VGA BIOS, since a Voodoo extension for the LGPL'd VGABIOS is not written yet.
