RAR archive of BIOS firmware for a Lenovo ThinkPad E49; the name gives no motherboard number, revision or firmware version, so contents should be inspected before use. At 2.83 MB packed it may hold one or more flash images. Such dumps are used to reprogram the SPI BIOS chip after corruption, board swaps or failed updates using a hardware programmer. Since ThinkPad E49 units shipped with different boards, compare the board number on the PCB with any notes inside, and save the original chip contents first.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
