IIgs appletalk startup

[touchstone]

hi,  i am tying to get a IIgs to netboot from a g3 mac and have hit 
kind of a snag.

first off, i have a vanilla rom3 gs w/ 2 meg ram.  i have os9.1 on the 
mac and gs/os
on 3.5 floppies.  the g3's appletalk connection is set to printer port, 
and the gs's
slot 1 and slot 7 are set to appletalk.  they are connected together as such.

i made the 'network 3.5 disk' on the gs, setup the appletalk network 
between the
two to automatically login to the mac, and installed gs/os onto the 
mac's startup volume.

the closest i can get this to work is to boot the gs from the 'network 
3.5 disk'.  i then get
a launcher window,  select disk until the macintosh volume appears, 
then i can 'run'
the finder from the mac.  the finder loads on the gs with the mac 
volume mounted, so i am
reasonably confident that the connection is working.

that's as far as i got.  if i set the gs startup to appletalk, the gs 
stays at the boot screen,
times out and starts from a floppy.  a google search indicated that i 
need 'appletalk
file server 3.0', but i haven't been able to locate this.

anyone have any ideas?

thanks,
