====== EEPROM External Read ======

===== Information =====

  * PiPROM ((https://github.com/grimdoomer/PiPROM))

  * Pulls EEPROM data from the chip on the motherboard using a Raspberry Pi
  * This was tested on 2017-08-16 with a SOIC8 Pomona 5250 clip on a v1.6 Xbox
  * This can all be avoided by backing up the EEPROM when softmodding ((seriously, don't ignore the warnings like I did and then need to spend 6+ hours trying to fix a mistake that could have easily been reverted and fixed in minutes with an EEPROM backup :p))

===== Prerequisites =====

  * [[linux;distros;raspbian|Raspbian]]

===== Enable I2C =====

****

  sudo raspi-config

===== Test I2C Reading =====

  * Requires the chip clip to be connected, and the Xbox powered on

  sudo i2cdetect -y 1

===== Broadcom BCM 2835 C Library =====

==== Download and Extract Source ====
