Question concerning booting a PC from a Nokia N800
 

I just recently got a Nokia N800, and I think it's absolutely fantastic. I was curious, however, as to its diagnostic purposes, so I decided to look into making a little portable diagnostics tool. I was curious if anyone knew a way to boot a non-functioning PC from the Nokia N800 (kind of like Apple's Target Disk Mode, I suppose). I know that there are bootable USB distros of Knoppix, but I'm not exactly sure how to go about this on the N800. Any tips on this end would be awesome and much appreciated- thanks!

I don't know what it means to boot one PC from another--I suppose there would be code that would simply transfer control to whatever boot code is in target PC. But why??---how would this be any different from using one of the boot disk utilities like the Ultimate boot disk, super grub, etc.?

Well, I wanted it so it could be a sort of all-in-one tool; I.E. if I were somewhere and someone needed help I wouldn't have to have a CD handy, I could just boot from the n800. It's not a super-pressing concern, just an idea and a cool hobby. I'm partway there, I think- I have a USB-bootable version of Knoppix on there by following these instructions (http://www.knoppix.net/wiki/Bootable_USB_Key) but it isn't detected by alot of USB-bootable BIOSes. I'll update as I figure it out.
