this is a repeat of a private email; i didn't think
this was going to be generally interesting.

option 1:
assuming the live cd boots, there is a test kernel on sources
in my contrib area which can be put into 9fat without booting
from the virtual hard drive.

	open a new window in the installer.  i'll assume that /dev/sdC0
	is your virtual hard drive.

	; cd /dev/sdC0
	; disk/fdisk -p data>ctl ; disk/prep -p plan9>ctl
	; 9fat:
	; cd /n/9fat:
	; 9fs sources
	; cp /n/sources/contrib/quanstro/9pcf.gz 9pcide.gz
	now edit plan9.ini.  add a second bootfile line like:
	bootfile=sdC0!9fat!9pcide.gz

now reboot and hope. :-)

(for those following along at home, the sdata.c i'm working from
is in /n/sources/contrib/quanstro/sdata.c.)

option 2:
install onto aoe storage.  vblade
	http://sourceforge.net/project/showfiles.php?group_id=130453&package_id=143790
runs on linux, if you have a linux machine.  or perhaps you could
run it on virtual pc.  (there's a version for plan 9, too.)
you'll need to put these lines into your plan9.ini

	# assuming that your vblade is running as 42.0
	# and you are using ether0 and ether1 to serve aoe:

	aoeif=ether0 ether1
	aoedev=f!#æ/aoe/42.0

(in any event, there are many ways to try to get this working.
e.g. if you had a seperate machine as a fileserver, you could boot
from it and be more free to experiment.)

dispite the gratitous ad hominem, i'm sorry that this is difficult.
unfortunately, i don't have a windows box or virtual pc.  thus
i can't properly test the change, even though it seems required
by the ata spec.

even if i did, it's presumptious to assume that the folks at the
labs have the time to review changes and incorporate them.
