Title: Bootloader Idea
Post by: Speedforneed on August 13, 2006, 11:47:31 AM
First off, I'm sure I'm not the only one that has had this idea cross their minds.   That being said, if one chooses to flash their firmware with the Rockbox firmware, would it be at all possible to boot the original firmware off the hard drive if they wanted to?  I realize that by default, it's both encrypted and like a 2MB file.  Aside from those 2 things though, would it even be possible?

I'm just curious.  It does not really benefit me in any way at this point.

Yes, it should be possible because original firmware runs from RAM after the ROM image has been copied to RAM. However, we need to find out first what part of the ROM image to copy, how to set all CPU registers, initialize hardware and what is the entry point to start excecuting original firmware code. After that, it should work.
