Find your xbox cromwell bios version

If you are running linux on your xbox, you may well have the cromwell bios on your modchip, a nice quick way to determine the version of your cromwell bios is to use raincoat to read it, then grep the bios image for version strings:

(On Xebian:)

su -
apt-get install xbox-raincoat
raincoat -r /tmp/biosimage
strings /tmp/biosimage | grep -icromwell

This should give you something like:

Cromwell 2.40
