BIOS firmware for the Dell Inspiron 15 3521 with an Intel Core i3 processor and AMD Radeon discrete graphics, linked to Compal board LA-9104P. The 3.13 MB RAR is meant for the discrete graphics configuration, so it may not suit UMA-only boards. Compal's LA-xxxxP numbering identifies the board design on the PCB. Technicians write such images to the SPI chip with a programmer to fix no-boot or corrupted firmware faults. Verify the board number and GPU setup, and keep a backup of the original chip before flashing.
