Thanks buddy. Me and my soldering station have awaited that answer. _________________ 320GB ST3320620A 7200RPM 16MB Cache

V1.6 Xbox the EEPROM is next to the LPC debug port labeled U7D1. (V1.0-v1.5 Xboxes the EEPROM is labeled U7C2. See attached photos.)
U = First letter identifier for an integrated circuit (inseparable assembly)
Other device type identifiers used on the Xbox printed circuit boards (PCBs):
R = resistor,
RP = resistor pack,
RT = thermistor,
C = capacitor,
L = inductor,
Q = transistor,
Y = oscillator,
D = diode,
CR = current rectifier (diodes),
J = connector,
SW = switch,
LED = light emitting diode,
FB = Ferrite Bead,
DB = ?? DBPAD - Test Point ??,
LB = label (e.g., serial number sticker)
7D = location on PCB, look at the edges of the board for the number and letter sections.
1A is located on the PCB's back right corner while looking at an Xbox sitting on a table with the front panel, controller ports and power/ejects buttons, facing you.
A-G rows - labeled along the left and right-hand edges of the PCB.
1-8 columns - labeled along the top (furthest from you) and bottom (nearest to you) edges of the PCB.
1 = unique number assigned to devices of the same type in this section of the PCB.
AtMel serial EEPROM datasheet attached below. The original Xbox uses a 2Kbit (256 x 8 bit) serial EEPROM to hold unique console configuration information.
For information on the Xbox's EEPROM content, visit xboxdevwiki.net's EEPROM page.

U7D1 for 1.6, U7C2 for the rest. Good stuff! It realy sucks they categorized every IC component with a U, should have broken it down just a little more. _________________ 320GB ST3320620A 7200RPM 16MB Cache

The naming follows electronics standards. For the designer, there's no problem as they know the part number of each chip in the schematic and each part is given a short label for the PCB silkscreen to locate the chip.
As a hacker, without the schematic, makes things a bit harder to determine the chip functions without looking up each manufacturer's part number. Nice they, Microsoft, didn't sand off the part labels as a few modchip designers do or relabel chips with the wrong part numbers.
