Compressed BIOS package for the Lenovo AIO 520 all-in-one, project code DCA30, on Compal board LA-E882P revision 1.0, dated 2017-04-11. Compal uses the LA-xxxxP numbering for boards it builds for Lenovo. The RAR needs extracting before use. Inside is usually an image ready to be written with an SPI programmer when the original firmware is corrupted. Check the board number on the PCB, back up the existing chip, and compare the image size with the flash capacity before programming.
