Understood. I need to understand a lot of things first. > Check the documentation for your _board_.

The firmware would not allow operation with another ISP and this ISP has since gone out of business. Other than the custom firmware not allowing ISP changes, it worked the same as anyone else. There is no documentation publicly available on this board. This board is based on a MPC850 processor, hence the reason I'm trying to get into it. I expect a lot of frustrating experiences trying to get this thing to work, but I don't see why I can't work my way through it. All of the solder connections from the 850 to the logic board appear on the opposite side of the board directly under the 850. With any luck, I should be able to trace out certain lines to verify what is connected to what. As for the other components present on the board, they're all easily identifiable. I think with a little bit of work, I can load u-boot and Linux on this thing. Thanks for the comments, Ryan Wilkins
