[9fans] Using nvidia TNT video card on installed system

[Brent Verner]

Hi,
  I've had good luck getting plan9 installed using the binary install image
from http://members.optusnet.com.au/~nwaples/binaries/, but after install my
system knows nothing of the nividia vga driver. What do I need to do to the
installed system to have it support the nvidia card. On a related note, how
do I access the mounted floppy? I've read the man page stating that 'a:'
mounts the floppy, but writing to '/n/a:/' gives me a 'hang up' error :\

This identifer line works for me, but only with vga/640x480x8 monitor in
plan9.ini:
	0xC00A2="Viper V770 AGP"

Thanks,
  Brent

The current kernel comes with an nvidia driver, but it's not compiled in by
default.  Edit /sys/src/9/pc/pcdisk and make sure there's a 'vganvidia.c +cur'
line with all the other video drivers, then change CONF=pcdisk in the mkfile
and mk.  Then "cp 9pcdisk /n/9fat" and point plan9.ini at it.

aux/vga also has to know about the card, but I think the current version does
by default.  Make sure /sys/src/cmd/aux/vga/whatever.c mentions nvidia in its
big video card dispatch table.

9fans archives have more detailed instructions, I think.

You mount a floppy by making sure dossrv is running and typing

mount -c /srv/dos /n/a: /dev/fd0disk

This is what the a: script does.  If dossrv hangs up on you, it probably
doesn't like the filesystem or the disk (tripping over a bad sector seems to
confuse dossrv enough to hang up that channel), or maybe even the drive.
dossrv and the floppy disk driver can be sensitive.

sounds like nvidia need some TNT, 'cept it's so unstable when it gets old.
