BIOS archive for a desktop motherboard named pm800 pro, 3.16 MB as RAR, with no brand or revision listed. PM800 is a VIA chipset name, but the exact board maker is not stated, so match the model on the PCB before using it. A dump like this is written to the BIOS flash chip with a programmer when a board shows no post after corruption. Read and save the existing chip first, and confirm that the extracted image matches the flash capacity, since an oversized file will not fit.
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.
