I just received my ChipKit-PI, downloaded and installed the recommended operating system and MPIDE package for the SD card. That works fine. Are there instructions available to load the SD card with the boot loader only, and switch to the operating system and MPIDE on a USB drive or hard drive? I do this with Raspbian by changing mmbclk0p2 to sda2 in the cmdline.txt file on the SD card.

Can you explain more of what you're trying to do?

If you want to move the image to a hard drive via USB you would just use "dd" and point to the new device.

To clarify: this is a Raspberry Pi question, right?

When I see the term "bootloader" used in these forums, it usually refers to the chipKIT bootloader (either USB or UART) burned into a PIC32 device.

But in this case, you're talking about the bootloader that resides on an SD card in the Raspberry Pi OS slot. It's an interesting idea, to host the RPi OS on an external USB device. As Rick suggests, it does not seem to be at all different from what you're already accomplished with Raspian.
