There's no real reason to clone the bios as we read/write the data: we're not doing anything in parallel and we're not servicing these bios on behalf of somene else whose original bios need to be preserved. This simplifies the code a bit, and plugs at least one error condition that was overlooked when I de-leaked this code. END
