Hello!

I'm excited about getting started with Plan 9, but I've run into one
problem.  I read all the documentation I could find.  I would have dug
into the man pages and papers more, but I thought it would have been a
stab in the dark.  I've included stuff from plan9.ini, vgadb, and
vgainfo.txt

aux/vga doesn't seem to be initializing my video card right.  I get to
the portion of the install where the display is initialized, and get the
black screen.

I checked to make sure the supported chipset was the one I have on my
card by looking at what Xwindows said.  It was indeed the mga2164w on my
Matrox Millenium.

I got the info from the BIOS from the video card from vgainfo.txt the
first time around.  The Text was at the right offset according to the
vgadb, but there was a different version bios, so I added it to the
vgadb - its the V2.3 line:


ctlr
        0xC002D="MATROX/MILLENNIUM  VGA/VBE BIOS (V1.9 )"       #
Millennium
        0xC002D="MATROX/MILLENNIUM  VGA/VBE BIOS (V3.0 )"       #
Millennium
        0xC002D="MATROX/MILLENNIUM  VGA/VBE BIOS (V2.5 )"       #
Millennium
        0xC002D="MATROX/MILLENNIUM  VGA/VBE BIOS (V2.3 )"       #
Millennium
        0xC002D="MATROX/MISTRAL  VGA/VBE BIOS (V1."             #
Millennium II
        link=vga
        ctlr=mga2164w linear=1
        hwgc=mga2164whwgc



I also changed the monitor entry in plan9.ini to match the one I have.
And I changed the vgasize to 640x480x8 to be safe:

*nomp=1 distname=plan9 partition=new ether0=type=NE2000 monitor=cpd-1304
vgasize=640x480x8 mouseport=0 audio0=type=sb16 bootargs=local!#f0/fd0disk
bootfile=fd0!dos!9pcflop.gz
installurl=http://204.178.31.2/magic/9down/compressed/974514989.t4893ntezs2y4
vh2vedvisfrqd9mz4wk



for reference heres what vgadb says about the monitor:

#
# Sony CPD-1304
# Horizontal timing:
#       Allowable frequency range: 28-50KHz
# Vertical timing:
#       Allowable frequency range: 50-87Hz
#
cpd-1304
        videobw=65
        alias=multisync


,so this too:

# Multisync monitors.  The entry with alias=multisync supplies the
bandwidth,
# which in turn decides the refresh rates when possible.
#
multisync
        alias=vga
multisync = 1024x768
        include=1024x768
multisync = 1024x768i
        include=1024x768i
multisync = 1152x900
        include=1152x900@70Hz
multisync = 1280x1024
        include=1280x1024
multisync = 1280x1024i
        include=1280x1024i
multisync = 1376x1024
        include=1376x1024


, and some of these by reference:

Thanks!  I hope someone can help with this.  I would really like to
start to use plan 9!
