#------------------------------------------------------ 
#This document describes my experiences installing Plan B on Qemu,
#specifically under Windows Vista. Note that, while this will let you
#run omero and other Plan B applications, not everything seems to be
#perfect. Most notably, /who and /mail are a little incorrect.
#
#1) Install a standalone Plan 9 terminal under Qemu. Just use fossil,
#no need for venti.
#
#2) From your new terminal, download the Plan B tarball from
#http://lsub.org/ls/export/planb4e.tgz using hget. Save it to $home.
#
#3) Run "con /srv/fscons" and type "srv instfs", then hit ^\ and type
#q to quit.
#
#4) "mount -c /srv/instfs /n/inst" We do this because you can't
#uncompress things directly into /
#
#5) "cd /n/inst && tar xzvf $home/planb4e.tgz"
#
#6) In my case, the omero that was included in the tarball wanted
#special fonts that I didn't have, so I recompiled it from source,
#which can use Plan 9 fonts. Do the following: 9fs sources mkdir
#$home/omero cp /n/sources/contrib/nemo/sys/src/cmd/omero/*
#$home/omero/ cd $home/omero mk cp 8.out /bin/omero
#
#6) Okay, here's where I'm not quite sure about the procedure. You
#need to specify where your root comes from, but it's unclear where
#the config file goes. I created /lib/ndb/vol/vols with the following
#line: /srv/vfossil main/active / / To be safe, I copied that file to
#/lib/ndb/vol/volumes, /lib/ndb/volumes/vols, and
#/lib/ndb/volumes/volumes. Only one of these files is correct, but
#I'm not certain which it is--haven't bothered to test.
#
#7) Run "cd $home/tmp && fossil/conf /dev/sdC0/fossil > fossil.conf"
#to get a copy of your current fossil config.
#
#8) Edit the fossil.conf file to look similar to mine: fsys main
#config /dev/sdC0/fossil fsys main open -AWP -V -c 1500 srv bfs srv
#vfossil fsys main srv -p cons srv fossil and write the new configure
#file with the command "fossil/conf -w /dev/sdC0/fossil
#$home/tmp/fossil.conf"
#
#9) Run "9fat:" and edit /n/9fat/plan9.ini to look similar to mine
#(you may need to change some options): bootfile=sdC0!9fat!9pcf
#bootargs=local!#S/sdC0/fossil bootdisk=local!#S/sdC0/fossil
#init=/386/bin/bns planb=yes sysname=zaphod #change this to match
#your config fs=127.0.0.1 auth=127.0.0.1
# *	nomp=1
# *	nodumpstack=1 partition=new dmamode=ask mouseport=ps1 monitor=xga
#	vgasize=1280x1024x8
#
#10) Go ahead and reboot, selecting root from local and user
#"glenda". You should get a standard rio screen, but if you sweep out
#a window and run "omero", everything should work properly.
