Very Computer

I have a Mach64 card...and like everyone else I can't get it to work
properly.  My question is if I can get some form of X up (possibly
not accelerated, but regular SVGA), I'd even accept 640x480 as a starting
place.

I don't have the RAMDAC chip that everyone else mentions,
SuperProbe on my system reports:

First video: Super-VGA
        Chipset: ATI (chipset unknown)
                Signature data: 5b (please report)
        Memory:  0 Kbytes
        RAMDAC:  Generic 8-bit pseudo-color DAC
                 (with 6-bit wide lookup tables (or in 6-bit mode))
        Attached graphics coprocessor:
                Chipset: ATI Mach64
                Memory:  2048 Kbytes

Nevertheless, when I try to run the XF86_Mach64 server, the screen goes
blank, but the computer doesn't die.  I think it sets the monitor in a
funny mode, but then killing X doesn't set it back.  The only way to get
back to text is to Alt-Ctrl-Delete it.

The output when I try to run the X-server is:

The other potential problem is that have a MAG DX17F monitor, where I don't
know all of the mode specs...but I'd expect to see something on the screen,
even it were fuzzy, or rolled.

I dont' know why, but for some reason, even though I have the same ramdac
problem as everyone else on my mach64, X detects the slow 640x480 mode,
and I don't get a blank screen. It works fine on 640x480x256 mode. (Just
lucky?) I had the same blank screen problem earlier, but for some reason
it solved itself mysteriously.

The problem is apparently the Clock chip (Bedrock) which is unsupported. I
have a similar card and posted the same query. This card has the video
circuitry, DAC and clock chip (programmable) on the same IC.

So, sorry, it seems this card is not supported yet.
If you can trade in your card for one that works, do so!

No, I think the MAG should be able to handle most modes you throw at it (at
least as high as 1024x768x8 at 70Hz)

Cheers
