Firmware dump labeled for board PCM-8212 at revision 1A, intended for an 8MB SPI flash and supplied as a RAR archive. A similar file tagged REV A1 also exists, so compare the revision silkscreen on your board carefully before choosing one. No brand or model is stated in the name. Use a programmer such as a CH341A to write the image after saving a backup of the existing chip, which preserves serial data and lets you roll back if the new dump does not boot.
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.
