Just a quick qestion about the x2 lite and re-flashing the bios

[MrCaine01]

OKay I'm gearing up to buy a whole new chip and put the newest bios on that bad boy...but I noticed everyplace sells the x2 lite with the linux cromwell bios. I was just wondering how easy is it to switch it to a newer bios? I'm getting really un-easy looking around at a few sites that are issuing warnings about turning your chip into useless crap and I'm just wonderinf how easy it was. If it's a real pain in the ass then I'd probably just grab the x2 pro and fiddle with the re-flasher thing it comes with. Anyway any and all help would be really great. Thanks!
