I've been reading up on flashing the bios and seem to be getting conflicting information if someone could clear this up it would really be appreciated.
If you got a machine in without a bios chip is it possible to get one from a donor board?
I read stuff like you have to get the ME region from the old chip etc. Then I also read stuff about "clean" ME regions.
Does a clean ME region mean it will adopt whatever the ME of the machine is? if so how is "cleaning" the ME region work.
Some people were talking about changing the serial in the donor chips to match the machine serial. And they were replacing it with "SystemSerial" then flashing a new serial with serializer.
Can't you just put in the new serial instead of putting "SystemSerial"?
It seems like to flash a bios chip it is recommended to take them off the board, but most of the videos i see use clamps while the chips are on the board.
Why is it important to keep the old bios chip's data when putting a new chip on.
I've also seen people say "you'll need to clean this bios file before using it" what does that mean?
Also seen "this bios is locked so only good for testing"
Some "guides" say to install a new OSX after messing with the bios or entering single-user mode, are these required?
I saw somewhere that hosted a load of bios files which you just had to replace the serial number, what about the ME region?
Maybe a sticky with this info would also be helpful to new members
