I haven't tried this yet, but it seems like the V3 IO Sandisk could be programmed by connecting a second PC to the IO IDE header with the IO's power off.
The sandisk should get power from the IDE power pins, and all the data pins should connect up to the header. The second PC would see the Sandisk as a slave IDE device. We could then put linux (or whatever) on the sandisk, boot the IO, and re-program the bios.
This may be how they program the Sandisks at the factory.
I plan on trying this method out tonight.
Anyone know any reason this shouldn't work? Will I fry some other components by connecting a second PC to the IDE header?
