Working BIOS for an EXO all-in-one PC, model L4, board identified as 7IR-H14BT4-TL50, packaged in a 7.02 MB RAR archive. The name gives no chip or version details, so inspect the extracted image size and compare it with the flash chip fitted on the board. Technicians use such a dump to reprogram a corrupted SPI chip with an external programmer when the machine does not start. Read and save the original contents before writing, and check the board code matches.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
