So does this mean that this should solve the problem with ATI's 'new'
chip added this summer? I have a new ATI Mach64 (Expression - I think!) with
1Mb DRAM. If I install the new Mach64 Server, should it now work? Do I need to
install any of the other beta stuff or can I get away with just the server?

Cheers

This is fine for the 20C408, but that chip must be obsolete. My new
ATI Mach 64 has a 20C498 clock chip. When I configure the screen to the
"640x480" settings I X -probeonly gives only 4 clocks any other
resolutions lock up the computer. Am I screwed. I just traded the my
trident 9440 in for the ATI because I knew the ATI was supported. Silly
me.

BTW, I am using 3.1.2 with the 3.1.2a Mach64 server. I am out of ideas.
Any help? please?

I emailed XFree. They replied as following...

Now I suppose you want to know about a possible patch...

>> Are you working on the 264CT ?

> Nope, but one of our developers is.

>> If you are, do you think it'll be ready before the new year ?

> No idea, but I guess that January is a more reasonable timeframe.

Hope this helps...

Does the RAMDAC have 20C498 printed on it, or are you relying on the
incorrect information reported by SuperProbe? The 20C498 is a RAMDAC
only. It has no clock chip. The 20C408 is like a 20C498 with a clock
chip added.

As I said in a recent posting, the 20C408 support in 3.1.2A beta version
requires you to add your own clocks line (including a selection of clocks
you want to be able to use), and also to add the line:

Option "program_clocks"

to the Device section of your XF86Config. This will not be required
in future releases.
