Firmware dump for the Inventec-designed LEDGER motherboard, part number 6050A2834801, revision MB-A01, packed as a 5.26 MB ZIP archive. The name gives no laptop brand or model, though this board number is used in HP EliteBook designs. The contents are intended for reprogramming the BIOS SPI chip with an external programmer such as a CH341A when the original image is damaged. Check the board number on the PCB before use, keep a backup of the existing chip contents, and verify the file size matches the flash memory.
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.
