on the empeg, first mount the disk read-write with the command:
# rw
then issue the following commands to switch off authentication in autostart:
# cd /etc
# cp init init.auth
# cat init.auth | sed 's#./displayserver#./displayserver noauth#' > init
# cp init init.noauth

Now you can change it quite easily:

auth on:
# cp init.auth init

auth off
# cp init.noauth init
