Lenovo 300e 2nd generation BIOS image, 16 MB in raw BIN form, labelled old and with an enrol or ast note that the name does not fully explain. No board number is given, so verify the motherboard against the device before use. A 16 MB image matches a 128 Mbit SPI flash chip. Read and keep the original chip contents with a programmer first, since an older dump may carry enrolment or serial data from another unit.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @anztechnology. Enginerys does not host this file.
