BIOS firmware archive for the Lenovo G460, labelled for a version with discrete graphics (VGA) and the Intel HM55 chipset, marked BD82HM55. The RAR is about 1.65 MB and most likely contains an SPI flash image intended for programming directly onto the BIOS chip. Use it to recover a board that fails to POST after a corrupted flash. Read and save the original chip contents first, confirm that the image size matches the flash capacity, and check that your board really carries the dedicated GPU before writing.

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 →
