Ok, so the machines hard lock and require power cycling them? I'd=20 advise throwing in a firewire card into one of these systems and=20 setup remote debugging. There should be some info on the web for=20 getting this setup. With the firewire debugging you should be able=20 to access the systems memory space remotely even if there is a hard=20 lock and the OS is not responding. I haven't setup this last part=20 myself, but I'm pretty sure I read it was possible. =2D-=20 Anish Mistry --nextPart5943302.6OXTtWR4BT Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (FreeBSD) iD8DBQBEMClGxqA5ziudZT0RAhp9AJ9yAjOsLwnTL+UHrVhVcIq9jto/ZACfbQA8 wtAZXiUeA4IfhTphcyqwnio= =3Mu6 -----END PGP SIGNATURE----- --nextPart5943302.6OXTtWR4BT--
