[9fans] Mach64 Support

[9fans] Mach64 Support

[Cameron Morland]

I have a spare PC and figured I'd give Plan9 a try. Specs: Intel
Pentium, 133 MHz, 48 MBytes (EDO), 1.7 GBytes. No funny hardware. I
downloaded the distribution this morning (Saturday 2001-10-06).

The first problem I had was with recognizing the video card, with is an
ATI Mach64 (I know because it says so on the chip). I get

So I guessed that it was failing to detect it because it's a different
flavour of Mach64. I added a line

        0xC00DE="MACH64GXPCIUYMM"                       # My ATI card

to vgadb. Now it successfully recognizes the card, but fails:

rom table offset FE

couldn't find ATI clock table

My plan9.ini file is as follows:

*nomp=1
distname=plan9
partition=new
bootargs=local!/bzroot
ether0=type=NE2000
monitor=multisync                     
vgasize=640x480x8
mouseport=0
bootfile=fd0!dos!9pcflop.gz
installurl=http://204.178.31.2/...

I also fiddled with the monitor and vgasize parameters, to no effect.

It seems to me that the card is supported, and I should just need to
configure it to accept the right dot clock. How?

I think we don't support the Mach64 GX,
one of the older Mach 64s.  The driver is telling
you it doesn't see the expected structures while
grubbing around in the BIOS, which I believe is
proof.

Sorry, I don't think there's much we can do.
