BIOS dump of 4.00 MB for a Lenovo ThinkPad E531 mainboard NM-A044 revision 1.0, with a VILE2 project tag and a U6 label that probably refers to the chip location on the board. NM-xxxx numbers are used by LCFC, Lenovo's own ODM. A raw image like this lets a technician recover a dead or bricked board by writing the SPI flash directly with a programmer. Match the NM-A044 code and revision on the PCB, confirm a 4 MB chip at the stated position, and save the original read before writing.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
