Duplicate 2.00 MB BIOS image for model 6730s, stored as a numbered second copy. Nothing in the name explains how it differs from the first, so compare the two in a hex editor before choosing one.

Back up the existing chip before erasing, and make sure the board in hand really belongs to the 6730s so the firmware fits the hardware.
