BIOS firmware for an Ultra Thin U45L notebook, with the board identified as 71R-C14CU4-T810 in the name, in a 2.67 MB RAR archive. The 71R-xxxx-T8xx code is a board number pattern seen on generic white-label laptops. The image is intended for rewriting the SPI flash chip with a programmer to recover a unit with no boot or corrupted firmware. Compare the board code on the PCB, back up the original chip before writing, and confirm the dump matches the chip capacity.
