Information I have gleaned from a multitude of sources says that on a
WD1002S-WX2 HD cntlr says that the W3 jumper controls the on-board ROM.

			Jumper installed     ---> ROM enabled
			Jumper not installed ---> ROM disabled

W3 is to the right of U11 with the board oriented with the connector fingers
to the right and down. W3 may actually be closed (comes from factory this way)
by a printed path on the board; the path must cut (carefully and cleanly) to 
disable the ROM.
