Hi,
Thanks for the help! I managed to get the framebuffer
to work (I can see the cute penguin logo during
booting up! :) )
I chose 0301 at the VGA prompt. The problem is when I
try to run a certain microwindows demo, say, "nterm" I
get the following error:
Cannot initialise mouse
Cannot open graphics
And on top of that, around 1/8 of the top portion of
my screen goes blank and the mouse hangs. I tried it
with 031A and even a larger part of the screen goes
blank...and the mouse goes crazy!
-Is there some specific VGA setting I need to use with
the Microwindows demo files?
-And how come my mouse stops working?
My graphic card is NVidia Riva TNT2 Model 64...it's
quite new so I guess it should be VESA 2.0 compliant.
Or am I making a wrong assumption here? :) I tried
checking the specs of the card on the nVidia website
but they don't mention anything about being compiant
with any VESA standard.
Thanks again & regards,
Supriyo
