you will need to create a bootable CD with xboxHDM by ltools (where did ltools go??) including the eeprom data file (BIN). This is all explained in the above guide
The disk is booted from a PC with the XBOX HDD attached to the PC not the XBOX (you will need a PC with IDE on it though). You boot the Linux boot disk, goes to a menu and then you lock the HDD from there. Then you should be able to boot the HDD from the XBOX.
But I would't worry about that bit yet, just try and read the eeprom. Then you can look at building a xbhdm boot disk.
I will see if I can find a premade image for you but you will need to add your eeprom.bin file from you xbox on to the ISO.
It's a lot to take in so take it one step at a time.
