[X4U] Macs which support "target disk mode"

[Terence Cozad]

Not to sound flip but it almost sounds like the computer lost power. I have
a mirror door G4 and have no problems with Firewire Target Disk Mode. If the
computer shuts down that is power related. I would plug into a good outlet,
make sure that the PRAM battery is good, if using a battery backup keep in
mind that putting too much in one will shut it down (from personal bad
experience) and you then need to plug into a different device or outlet.

If it still does not work I would suspect hardware or a bad firewire port
perhaps. Try the other port. I know the old Blue and White G3 could not boot
this way from the firewire port (I had one) but all towers since then
should. 
Just my 2 cent but hope you get it figured out.
