The Xpert98 should work; hopefully all that's
wrong is the recognition of the card for what it is.

After making the boot disk, edit a:\vgadb
and look for the section with all the Mach64
entries.

Add the marked line (without the >>>)

	0xC0000-0xC0200="MACH64GB"
	0xC0000-0xC0200="MACH64GM"
>>>	0xC0000-0xC0200="MACH64GR"
	0xC0000-0xC0200="MACH64GZ"

and try booting again.

Thanks for the help - the installation is now one step forward.  It tries to
switch to graphics, but then produces garbage.  My monitor (a Dell M770,
Hsync 30-69 kHz, Vsync 48-160Hz) just says "Signal Out Of Range".  I haven't
got a 'scope so I can't examine the signals. I notice that in the default
PLAN9.INI, the monitor is selected as "multisync75".  In case this is the
problem, I tried changing this to "micron-17FGx", since the frequency range
for this monitor is stated in VGADB to lie within the range of my M770.  No
difference.  Any suggestions?

Best wishes,

Keith.

This problem is now fixed.  The card works with Charles Forsyth's modified
boot disk (see his earlier message for details).

Hm, since the symptoms resembled what I saw for the RAGE-128,
does that mean we can get the RAGE-128 to work now too?

and the line added to /lib/vgadb as russ noted:
