BIOS binary for the HP 250 G4 laptop built on motherboard LA-C811P, an 8 MB full SPI flash image. The LA-xxxxP pattern is Compal's board numbering, so HP used Compal as the ODM for this platform. A dump like this is used to reprogram the BIOS chip with an external programmer when the machine fails to power on or start after a bad update. Check that the LA-C811P code silkscreened on the PCB matches, save the original chip contents first, and verify the chip is 64 Mbit before writing.

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