Hello,

I have tried to install Plan9 on 3 PCs, 2 of the installs had  different
problems with video chipset (both different versions of ATI Mach 64),
one PC did not boot ("incorrect boot syntax" - after showing some
scribbly characters first)

The 2 video cards observations:

1.

I got one of the ATI Mach 64's finally working, I ran "DOS debug" and
found the following MACH64 setting

0xC00E9="MACH64VTPCIU"                          # my Mach 64 on AMD
system

When I add it to "vgadb", the install works(at least as far as switching
to "rio"

Should stuff like this be send to 9trouble@plan9.bell-labs.com so they
can add it to the distribution?

2.

My other (newer) Mach 64 is recognized as "MACH64CTPCIU", but when
trying to start the vga, I get a message:

aux/vga: mach64xx: no linear aperture aux/vga:....

and later:

rio:54:suicide:trap:failure read addr=0x18 pc=0x00011e7e

I tried to play with the linear= setting in the vgadb, but no luck....
