RAR archive holding both BIOS and EC firmware for a board identified as WTM-H610 with code B23110176. H610 suggests an Intel H610 chipset, but the name gives no brand or model, so match the board label exactly. Having both images lets you reflash the main SPI BIOS and the embedded controller chip, which handles power, keyboard and charging. Use a suitable programmer, back up each chip before writing, and check that every image size matches its chip.
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.
