BIOS image for a board identified as B40IA1 revision 01, with the Intel Management Engine region cleared so the ME starts fresh after flashing. The ZIP is 1.41 MB and no laptop brand or model appears in the name. A cleaned ME region helps fix symptoms like fans running at full speed, shutdowns after a set time or refusal to boot caused by a corrupted ME. Confirm the board marking matches B40IA1 rev 01, read and store the existing chip contents, then program the SPI flash with an external programmer.
