assmeblers and disassemblers

Hey Scott.  In any device (including EFI) that has a microprocessor of some
sort, there is some code, or a program, that tells the processor what to
do.  An assembler is a piece of software that allows you to create this
code, or program, that displays all the commands in an human-like readable
form.  After you write your code, the assembler "assembles" or converts
those readable things into "machine code", which is what the microprocessor
understands.

A disassembler is the reverse - it takes the machine code which means
something to the processor, and converts it to something that you and I can
understand.

For example.

LDA $FF

The above means "load the A register with value $FF (which is 255 to you
and me).  The assember converts this to:

08FF

The microprocessor likes the latter, people prefer the former.  Hope that
answered your question without making it more confusing.
