Lenovo T48S BIOS image in raw binary form, 16 MB, with the name noting that MDM data is included, which usually refers to device-management or ownership settings kept in the firmware. The file name gives no board number or revision, so check the motherboard markings and the flash chip label before using it. A 16 MB image suits a 128 Mbit SPI chip. Read and save the original chip contents with a programmer such as a CH341A first, then write this dump and verify it against the chip after programming.
