HP 15-bs013dx BIOS package for the CSL50/CSL52 platform on Compal board LA-E801P revision 2.0, with the extra token 24B64CSIG whose meaning is not certain, in a 5.45 MB RAR archive. LA-xxxxP is the Compal ODM pattern found on many HP notebooks. Such a dump is written to the SPI flash with a programmer when the laptop fails to start or shows a black screen. Keep a backup of the original chip, confirm that LA-E801P Rev 2.0 is printed on the PCB, and check the image size against the chip capacity.
