BIOS dump packed in RAR for an OPS-H81 board labelled T1702 v3.0, with a 4MB image size stated in the name. OPS-H81 suggests an Intel H81 based embedded or OPS slot computer module, though no brand is given. The image is meant to be written to the SPI flash with a hardware programmer such as a CH341A when the unit fails to post or the firmware is corrupt. Make sure the chip on the board is 4MB, compare the version marking, and save a read of the original chip before flashing this file.
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 @biosarchive. Enginerys does not host this file.
