BIOS archive for the Dell Alienware 15 R2, motherboard LA-C912P revision 1.0, with the project code AAP21 included in the name. The LA- prefix is Compal numbering, so Compal manufactured the board for Dell. The RAR, 5.71 MB, is intended for programmer-based recovery of the SPI flash when the laptop shows no post or a corrupted firmware. Confirm the board number and revision on the PCB, and dump the original chip first, as service tag and other system data are stored in that region.</description>
