BIOS image for model 4740s, 8.00 MB in .bin format, with no board number, revision or version in the name. The size matches a 64 Mbit SPI flash chip, and on platforms of this generation a full dump usually contains the Management Engine region as well as the BIOS. Technicians use it to reprogram a corrupted chip with a CH341A or similar programmer. Read and keep the original chip contents first, confirm capacity and model, and verify the write afterwards.
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 @biosfilebins. Enginerys does not host this file.
