Anyway trying to upgrade form non debian dist to debian (potato) on my
7220/200, as it is old world I used the hfs floppy image. Anyway it boots
fine but then the video mode is at a frequency such that no text is clear
and it is moving around on the screen a bit (like running X i modes a
machine cant handle)

You cant pass a video mode to platinumfb.

it is a Mach 64 video card

Do you have 834x624 and more than 8 bit color depth? If yes, change the
resolution or set the color depth to 8 bit.

wouldnt doing this involve the passing of a video=atyfb:vmode:8 or some such
?

	See You

vmode for resolution, using values available in nvvideo's manpage
cmode for color mode (bit count works).

in reference to the nervous text, I get this on my PDQ when the mclk is
set incorrectly.  this can be specified using the mclk: param.  my
cmdline is "video=atyfb:vmode:14,cmode:32,mclk:100", but I am aware that
earlier systems, even wallstreets use smaller mclk values.  the
default/autodetect in the kernel does not work for me.  could try 83 or
60, two other fairly successful values IIRC.

Hope this is helpful.
