oh, well, if you don't know what soldering is, then I would get the plus version.

X2 pro = a chip with a 1mb flash rom, capable of using 4x256k bios, 2x512k bios, or 1x1mb bios. Also can be recover from a bad flash (which almost never happens unless you lose power). You have to solder this chip to the board.

X2 Lite = Chip with 1mb flash. Can have 2x512k bios, or 1x1mb bios. Flash recovery isn't gauranteed. Yo uhave to solder this chip to the board.

X2 Lite Plus = Same as above, but is solderless. You can just plug the chip onto the xbox mobo.

Solder= a string of lead, basically. For the chips that require soldering, you have to stick the chip wires to the mobo by melting the solder onto the points. You can really do some damage if you don't have a stead hand, a soldering iron with a too big of a point, or have never soldered before.
