BIOS image for the Dell 7391 on the Wistron WASP13-MB board, number 18739-1. The dash-one suffix is the Wistron revision field, and it should match the marking near the board number on the PCB. Technicians write images like this to the SPI flash with a programmer when a board shows no power or no display after a corrupt update. Save a copy of the original chip first so that service tag and system data can be restored if needed. Confirm the chip size against the image before programming.
