boot1 - f01e

hallo..
one easy question:

people often talk about the f01e boot1.. (i allready know that its nun vulnarable)

were could i find the boot1 version "f01e" in hex file ? witch adresse is the correct one.. ?
ist the any explanation on this in the net ?

thanks !

That's a SHA-1 hash. The hash could manually be checked by decrypting boot1 and calculating the SHA-1 hash. However Hackmii installer automatically checks boot1 for the fakesign bug.

ok one step after the other... i now know that this is the "hash".. how to build this hash ? what is the exact part of the bin for hashing boot1? t thing 0-20FFF ?
