BIOS dump for the Dell Latitude E3340 on Wistron board 13229-1, an 8 MB raw binary matching a 64 Mbit SPI flash chip. Five-digit numbers with a dash revision suffix are typical of Wistron designs built for Dell. Technicians use such an image to reprogram the flash chip with a CH341A or similar when the laptop powers on without display or is stuck after a failed update. Read the original chip first to keep the service tag and system data, and verify the board number on the PCB.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @afsbiosfree. Enginerys does not host this file.
