XENV

From t-hack.com - Hack X300T / X301T

This is a data structure that contains information about the hardware configuration and other system parameters.

The whole data structure has a SHA1 value to detect corruption.

these are not all the values found in the x300t XENV, but most of them are not used anyway.

the prefixes of the values indicate where they are used:

 * x - used by XOS
 * z - used by Zboot
 * l - used by Linux
 * w - used by Windows
 * a - used by all
