Hi,

yes, a modchip should help. With a modchip and a proper bios installed, you can boot the slayers disk, even with a blank harddisk in the xbox. Slayers gives you the option to partition and format that disk so that you can install a new dashboard on it.

Most modchip's install on the LPC holes. You need to solder some header pin's in those holes and connect 1 additional wire to the D0 point of the xbox. That one can be found on a couple of via's and also on a testpoint on the bottom of the pcb. The 1.5 mobo versions and higher need a LPC rebuild board to connect a modchip. Some of the LPC signals are no longer connected to the holes.

The eeprom reader only requires to connect 3 wires to the LPC holes. In my opinion, it is a valuable alternative. You will need to prepare your harddisk on a pc, and a laptop can't be used for that.

regards.

I don't have the original eeprom. It is completely lost. I've tried getting it from the laptop but there's no hope.

Will I need it? Or will the mod chip do all the work for me?

-Or -

Can I use the "new" xbox's eeprom and files to rebuild a new hdd?

Hi,

the eeprom is a small 256 byte memory chip in the xbox. So, unless you desolder it from the motherboard, you can't loose it. The chip contains information that is unique for every xbox. Part of that information is the hddkey which is used to calculate the hdd unlocking password. Due to that, the harddisk from xbox A can not be used in xbox B.

What you lost is a backup of the contents of that eeprom chip. It is a small file that contains the same information as the chip. Packages like xboxhdm use it to calculate the xbox unlocking password.

The modchip biosses are modified so that they allow the xbox to boot normally, even when there is an unlocked harddisk in the xbox. Because of that, you don't need the eeprom.bin file to make things work again.

The eeprom reader reads out the small memory chip directly. Even when the motherboard is not functionning, you can still read out the eeprom chip in most cases.  

regards.

***UPDATE***

I wrote down my hdd key a while ago and I have it. It is 31 digits.

First of all, is that enough digits for an hd key?

And second, if so, can I use this number to rebuild a new hard drive? (using the contents of c and e on my new xbox)

Thanks again

the Unique HDD Key needs to be 32 chr to make a eeprom.bin that will work with xboxHDM

a HDD password is 40 chr (different then the Unique HDD Key)

ok, eeprom reader it is.

thanks for your help
