Re: [9fans] ATI Xpert98 "OEM" Edition - doesn't work with Plan9

["Keith Nash" <k.j.nash@usa.net>]

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.
