vonstroheim@my-deja.com:
	Has anybody manage to use a 3dfx banshee PCI card with plan9 ?

	I modified the vgadb file to force the use of the voodoo3 driver but it
	failed.
	I got the following message (dumped in vgainfo.txt):

	main->snarf
	vga->snarf
	3dfx->snarf
	sequencer->enter on
	sequencer->leave on
	3dfx: unknown chip - DID 0003

I've not tried this as I don't have a Banshee, but I believe it will
work if you add the chip id in the two places it matters, i.e. in both
/sys/src/9/pc/vga3dfx.c and /sys/src/cmd/aux/vga/3dfx.c look for all
cases of

		case 0x0005:		/* Avenger (a.k.a. Voodoo3) */

and add

		case 0x0003:		/* Banshee */

(make sure tyou get them all, there's motre than one in the kernel
driver).

Let me know if it works and I'll add it into the distribution.
Good luck.
