Can't remember. We tried quite a few different ones. In the end, it
was easier to change the card than to use ed. ;-)

I found a DX card and fixed the cursor problem. The ID code for the DX
was wrong in both /sys/src/cmd/aux/vga/virge.c and /sys/src/9/pc/vgas3.c.
In both, replace all instances of

	case 0xE18A:				/* ViRGE/[DG]X */
with
	case 0xE101:				/* ViRGE/[DG]X */

This fix will be in the next update.

As successive generations beat their heads bloody against the vagaries
of aux/vga an older card sometimes falls by the wayside. I'll see if I can find
a DX tomorrow and get the cursor working again. It might have been this one:

We tried a DX. We got the graphics working easily, but the cursor didn't work
properly -- had 2 stripes about 100x300 pixels below it.

did you start with the Trio64 definition or Trio64V+?  when i lied to
vga and told it my Trio64V2 was really a Trio64 an extremely similar
effect occured, where the two stripes were rectanges about 10px high
and ~30px wide.  using Trio64V+ as a baseline made the problem
go away. [err, perhaps vice versa.. i'm away from Plan9 right now :<]

  I tried booting the install disk, and it didn't work(ended with a
 % prompt), and it did show info about not finding the controller
 in lib/vgadb.

  Anyway, I'll probably have to wait before DX is supported.

The suggestion is to use it as a GX, with the funny cursor shape.  It
worked adequately for installation purposes.  The vertical bars are
non-destructive.

I'll be keen to see that as well.  I thought my Diamond Stealth was
quite a spiffy card, but it seems everyone has far more graphical
power than I ever thought I would need (32 Meg on the card?).

  My video card uses the S3 ViRGE/DX chipset. The hardware
  requirements for Plan9 says it supports ViRGE/GX, GX2, VX, and MX.
  I wonder if DX is compatible enough to work.

I did have a DX card at one point and it worked. That was before various
overhauls of the code so your mileage may vary.

[9fans] S3 ViRGE/DX?

[Belldandy]

  My video card uses the S3 ViRGE/DX chipset. The hardware
  requirements for Plan9 says it supports ViRGE/GX, GX2, VX, and MX.
  I wonder if DX is compatible enough to work.

  Also, Plan9 video chipset support is quite scarce right now.....
  Is anyone writing other drivers?
