Found another novel way to read the Xbox's EEPROM on a computer running Linux with a VGA port posted by Jesenko Mehmedbasic. (Note: DVI and HDMI ports have the I2C interface too)

Yes, through the VGA connector!  It has an I2C interface to read the Extended Display Identification Data (EDID) stored on a serial eeprom in the monitor.

Thanks for share! and question about a serial eeprom the original is CAT 24WC02J,the other brands like ST and MICROCHIP also compatible? find this M24C02-RMN6TP by ST.

Looks like it should be compatible.  Just need to make sure the package's form factor fits the pad layout present on the Xbox's motherboard.  

SOIC-8

I see Digi-Key has them SOIC-8 packaged chips available in many different deliverable package types:

  • cut tape
  • bulk
  • tube
  • digi-reel
  • tape & reel
  • etc. 

Some deliverable packaging types can be purchased with a minimum quantity of 1 while others like tape-and-reel require a 2500 or 5000 minimum quantity (1 entire reel).

 

bulk packaging, min. quantity 1 but for $0.12 each instead of $0.11 as your original posted item.
