Backup BIOS dump labelled for the P5KPL-EPU motherboard, a raw 1.00 MB binary. The backup tag suggests it was read from a working board, which may preserve board-specific data such as the MAC address and DMI information not present in a stock update file. Technicians write such images back to the flash chip with an external programmer to recover a board whose firmware is damaged. Since it came from another unit, be prepared to correct serial or MAC data afterwards, save your own chip first, and verify the chip capacity matches.
