BIOS firmware package for the Dell Precision 7740 mobile workstation built on Compal board LA-H281P, with the Intel Management Engine region repaired so the machine no longer hangs or throws ME errors after a flash. The RAR is 21.6 MB, so expect more than one image inside. LA-xxxxP numbers belong to Compal, the ODM behind many Dell laptops. Confirm the LA code on the PCB, read and save the original SPI contents with a programmer first, and check each image size against the chip before writing.
