Magical Hex values.

Hexadecimal values (0-9, A-F) can be used to create some magic words (like 0xDEADBEEF) which are useful in debugging the software/firmware, especially memory related code. The alphabets A-F can be used (obvious!) and additionally other alphabets can be modelled from the digits 0-9 - e.g: '0' representing the letter "O", '1' representing the letter "I"/"l", '5' representing "S", '6' representing "G", and '9' representing "g".

Here is a list of few codes used by the computer/OS giants:

* 0xABADBABE :"a bad babe" - used by Apple.
* 0xBAADF00D : "bad food" - used by Microsoft.
* 0xBADCAB1E : "bad cable" - used by Microsoft.
