BIOS archive for board 6050A2728501-MB-A01, revision A01. The name lists 25Q128 and 25Q64 chips, which suggests separate images for a 16 MB and an 8 MB flash. The 6050A numbering belongs to the Inventec board scheme, used for many HP notebooks, though the name does not state the laptop model. At 21.5 MB the RAR likely holds several dumps. Write each one only to the chip whose capacity it matches, using an SPI programmer, and save the original contents first.
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.
