Archive for the ECS P4M800PRO-M motherboard, 891 KB in RAR format; no revision is given in the name. Read the revision from the PCB silkscreen and compare it against the documents inside. This board is a separate model from the P4M800PRO-M478 variant. Extract the files to see whether they include a schematic, useful for tracing voltage regulators, power sequencing and faulty components, or a BIOS image to write with a programmer. Save the original chip contents first and confirm the image size matches the flash.
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 @IT_SERVICE_WORLD. Enginerys does not host this file.
