    SubjectRe: Compactflash cards dying?
    Take a look at all the embedded Linux distributions.  There are 
    solutions for this out there. I haven't looked into them as I just
    stuck a hole PC into my robot.

    The issue with ROM style data storage is once written, any changes
    require replacement of the devices. That adds up after a few revisions.
    All motherboards once had PROMS (usually windowless EPROMS) for
    storing the BIOS. It is just the cost of FLASH type devices has come
    down to the point where they are cheep when you look at the costs of
    going about it some other way.
