BIOS package for the Acer Aspire E15 E5-511-P7UX on Compal board Z5WAL, number LA-B211P, revision 1.0. Compal manufactures many Acer Aspire boards and prints the LA code and revision on the PCB, so check both against this file. The rar holds an image used to restore the SPI flash with an external programmer when the laptop has no display, freezes at the logo or was bricked by an update. Read and save the existing chip first, and make sure the image size matches the flash capacity.
