Second copy of an 8 MB BIOS image for the HP 250 G4 on Compal board LA-C811P, kept alongside another dump of the same model. Having two reads allows a technician to compare them byte for byte and spot a bad or unstable read before using either. Compal LA-series boards usually store BIOS and Intel ME together on a single SPI chip, which is reprogrammed with a CH341A or similar tool. Verify the board number on the PCB, back up the original flash and confirm the chip size before you program it.
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 @biosfilebins. Enginerys does not host this file.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
