Since it appears that [[GNU GRUB]] developer [[User:Robertmh]] came up with this concept (and integrated it into GRUB), should he be credited? Or should it at least be clearly stated that this is an invention by the [[GNU GRUB]] team, so people know where this concept came from? —[[User:Hobart|Hobart]] ([[User_talk:Hobart|talk]]) 07:29, 28 February 2012 (UTC)

== Hah!IdontNeedEFI confusion regarding endianness ==

Much confusion has arisen regarding endianness of the "Hah!IdontNeedEFI" GUID:

Look at the fine [http://en.wikipedia.org/w/index.php?title=BIOS_Boot_partition&action=history history]:

I've gathered the following pieces of information in trying to understand it all:

* The first three fields of a UUID/GUID are a 4-byte value, then 2 2-byte values. All subsequent values are single bytes or byte arrays, so only the first 8 bytes are affected by endianness concerns.

* The typical way to write a UUID/GUID's string form in RFCs / Linux-centric documentation is big endian.

* However Microsoft sources tend to write UUID/GUID string forms little endian.

* The byte order of an on-disk GPT is little endian.
