Grant, If you have more than one system there, you can set the system to use the serial port as a console. Then run a serial cable into the second system and ssh into it to watch the boot process. Getting the keyboard to work correctly via the ssh --> console-over-serial-port can be tricky so it's best to set it up before you deploy remote hardware. Also, I have used a cheap ebedded linux system when the second system is not available. Years ago, I even built a "reboot box"; it was an embedded system with 4 relays and a 2 serial ports connected to different system. I could physically remotely toggle the power. Several companies build these devices, but, I have not used one in years. Here is a google example I just found (never used this product) http://www.youtube.com/watch?v=s9odA7LH91c Just find a cheap embedded linux board with a 3-5 VAC(120). hth, James
