C5W1R LA-D661P (REV 2.0)

BIOS .rar 2.81 MB Shared

Firmware for a Compal board LA-D661P, revision 2.0, with C5W1R noted as the project code, stored in a 2.81 MB RAR. The name gives no laptop model, EC version or chip type. LA-prefixed numbers are the Compal pattern found on many notebook brands, and the code sits on the PCB silkscreen. Technicians use such dumps to recover a board after a failed update or corrupted flash by writing it with an SPI programmer. Keep a backup of the original chip and confirm the revision and image size before flashing.
