BIOS firmware for the Lenovo ThinkPad Edge E335 with an AMD platform, Wistron board LPR-1.1, number 11304-1, compressed as a 4.86 MB rar. Wistron uses five-digit numbers with a dash suffix for its mainboards. Repairers write such dumps to the flash chip with an external programmer to recover a machine with corrupted firmware or a black screen. Check that the board number on the PCB matches, back up the original chip before erasing it, and verify that the image size equals the chip capacity.
