The days of 'soldering a new chip' are just about over, at least for many folks. The 'chip' (if it is even a separate chip) will be surface mount, which requires a special setup to rework, and even then, it would likely be challenging to get the balls on the chip lined up with the board. Even professional rework shops have troubles sometimes reworking flash/memory chips.
I don't know how the bios flash is arranged on the 10v. Dell will have a reflash procedure they can do in a depot but it might involve a JTAG unit (a special hardware debugging tool) or other specialized software and hardware.
In short, don't screw up. :-)
