This has been done. It's now i82371eb.
Why not 82371eb (that's the official name AFAIK)? Is there some requirement that directories have to start with a letter?
Its a C thing. You can't start a variable with a number. That allows you to match the directory name to the struct statements in the code.
Why not call it piix4e (or just piix4), much easier to type and proofread and understand in general?
