BIOS files for the MKB-L14 board, 7.89 MB in rar form, with both 8 MB and 16 MB images included. CML indicates Comet Lake, Intel's 10th-generation platform, and UMA means integrated graphics without a discrete GPU. The figure 197462 is also part of the name, likely a project or part code. Pick the image that matches the capacity of the SPI flash fitted, since a mismatched size will not program. Read the original chip and store the dump before writing, and verify the board label before use.
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.
