Instructions
Remove any power cables and accessories from the rear of the Xbox 360, and then remove the front faceplate from the system. Lift the plastic tabs on the outer casing of the console and remove the outer plastic case. Unscrew the Torx size 7 screws and slide open the metal interior case.
Lift up the DVD drive and disconnect the SATA cable from the DVD drive to the motherboard. Connect your SATA cable from your computer to the Xbox 360 motherboard and turn on your computer.
Open a web browser and download a freeware Xbox 360 BIOS program, such as the ones listed in the Resources section. Run the BIOS program and select your Xbox 360 from the application's main menu.
Select the "Motherboard Options" tab and click "Extract BIOS." Check the box marked "Foxconn Extraction" and click "OK." The program will then extract your Foxconn Xbox 360 BIOS and save it to your computer's hard drive.
Close the BIOS program once the Foxconn BIOS extraction is complete and shut down the computer. Disconnect the SATA cable from the computer to the Xbox 360 motherboard, and then reconnect the SATA cable from the Xbox 360 motherboard to the DVD drive. Close the metal cover and rescrew the Torx size 7 screws.
Replace the outer plastic case and return the front faceplate to its original position. Reconnect any power cables and accessories before powering on the Xbox 360 console again.
