Sony board MBX-266 BIOS image with the Intel ME region cleared, for the HM76 chipset, packed as a RAR. A cleaned ME region lets the Management Engine rebuild its data, which helps with boards that power on but fail to start properly after corrupted firmware. MBX numbers are Sony's own Vaio mainboard designations. Write the image to the SPI flash with a programmer, but first read and save the original chip, and check that the dump size matches the flash capacity.

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 →
