Okay, I've got my eeprom on my comp. and PC, and it says its 1 KB on the PC. Is this the full eeprom? Also, when un-installing SID 2.0, do I just select "restore MS dash"?

1 - The eeprom is only 256b, so it's not even 1k.
2 - What do you mean by SID?

The crappiest installer ever, the Softmod installer deluxe 2.0. Anyone know the answer to that? And thanks for that answer, that's a relief that I have all my eeprom backed up!

Ah, it must be pretty crappy, I've never even heard of it.

If you are positive that SID can restore your Xbox to normal go for it.

If not, if you have FTP access get the slayers original C files (usual places) and send those over.

If you don't have FTP, get XboxHDM (also usual places) and put the slayers C files in there. You'll have to open up your xbox for this one.
