Firmware dump labelled DP55M01 revision A00 with the extra identifier 922D1P29, compressed to 719 KB. The name names no laptop brand or model, so the board must be identified by its own DP55M01 marking before use. A file like this is usually written straight to the BIOS or EC flash chip with a hardware programmer when the board will not boot or the firmware is corrupt. Save the original chip contents first and check that the extracted image size matches the flash capacity printed on the 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.
