noob to DBOX2 stuff ( but not to embedded linux tho

If I buy a pre-flashed box with neutrino for example, can i still extract the ucodes, and are the ucodes specific to each individual box or just the given hardware version (ie Manufacturer an PCB revison).
some more general linux Q's
is the kernel 2.4 or 2.6 ? Am i right in assuming it is using BusyBox ?
Is the On Screen Display managed using FrameBuffers ? if so is it using Nano-X ?
Soz for all the questions, just moved into a cable area so v.excited about playing with some new hardware.
