Changes

*The encrypted MBR has the header of "IGS-I-JOIN-C1000" and the BIOS has elements of GRUB strings to do check against. It's not possible to boot from other boot drives like USB without the header and GRUB strings present; it will fail with "Boot False(B)."

*Similar to its predecessor, it also has a check for the Texas Instruments Ti1510 chip embedded inside the board after the POST screen. It will fail with "Ti1510 is not Exist" error if it doesn't find one on the board.
