    Acronyms

    Is there a list of what these acronyms mean? Example what does $OD mean
    Hope this is the right area to ask this question.

    Close enough...

    When you see us refer to something with a dollar sign it is hex as oppsed to decimal. In this case you will see a lot of $0D , $42, $6E etc... these are the mask ID for the chip. The mask is like a map of where the code is to change in hex.

    If you scroll down the maini forum you will see the EFI Dictionary that will help you get going on many acronyms.

    Okay, thanks. Up early to get the "now running perfect Bronco" ready for the Rubicon. I'll check this out in a week. I have GOT to learn this stuff.
