BIOS image for an M70t desktop, Type 11EU per the name, flagged as tested OK. No brand is stated in the filename, so confirm the machine type on the service label matches 11EU before using it. The 10.1 MB RAR archive should contain a full flash dump for writing onto the SPI chip with a programmer such as a CH341A or similar, useful when a failed update leaves the system dead. Save a copy of the existing chip first, check the dump size against the flash capacity, and verify with a read-back after writing.
