BIOS image for a motherboard numbered 15341-1, a pattern used by the ODM Wistron, with the extra token 91n85 in the name, likely an internal board or project tag. The 16 MB size points to a 128 Mbit SPI flash chip. Technicians write such a dump with a programmer like a CH341A or RT809 when a board is dead or bricked after a failed update. Confirm the 15341-1 marking and revision on the PCB first, and save a full read of the original chip before erasing, as it holds serial and licence data.
