Subject: Re: [9fans] Installing without graphics ?
Date: Wed, 14 Jun 2000 16:36:55 -0400	[thread overview]
Message-ID: <200006142040.QAA08102@smtp1.fas.harvard.edu> (raw)

  1) Is there any way to install the system without vga and rio up
  and running. I need an installed system if I am going to be able
  to play with writing a driver for my card.

You could carry out an install without
vga and rio, but only by hand.  You'll find
the system unusable in text mode for the
purposes of writing a video driver anyway.
Much better to get going on a different
video card first, so as to have a decent
development environment.

  2) Where would be the best place to look for starting to write a
  graphics driver. How much work is done by the card specific code ?

Not a lot, especially if you punt on the
hardware acceleration the first time 'round.
Mostly it's just setting up registers correctly
for the given mode.
