hey,
  
     can someone please tell me what a Multiboot header is?, and please dont throw all of the OS terminology mumbo-jumbo at me... I am very new to this stuff, thank you all very much!

A multiboot header is a piece of data or some variables, inside the top of your operating systems kernel (the file that gets loaded into the computer by the multiboot bootloader)

It states a few facts about your kernel such as where parts of it lie, such as the code the variables and the uninitialised variables are, and some other possible facts such as what information you want out of the multiboot bootloader, such as memory maps and facts about your computers disk drives.
