Thank you. I think I'll try iND bios. But just one more question: what about the Hard Disk? I have to re-lock it?
No. iND supports unlocked HD.

I have to format it in FATX and/or create a new xbox disk from scratch with XboxHDM, or I can just use FAT32 or other Unix filesystem?
I would suggest restoring the HD to stock state (clean set of M$ "C" drive files) at least.
The tough part is going to be getting cromwell off of the TSOP, and iND onto the TSOP. I can't remember how I did it (accidentally flashed it to my TSOP) years ago.
EDIT: I remember how I did it. You can take the linux files from a eurasia flash disc and copy them to the HD where your linux install is, whether it be C or E and overwrite the old files. This way, when the linux box boots, it will load eurasia instead of the old linux OS and flash back to hacked bios.
