Firmware package for the Dell Precision M5520 and XPS 9560, which share the Compal LA-E331P mainboard; the name marks it as the main BIOS dump, with UH8 possibly a chip location label. The 7.98 MB RAR suits reflashing the SPI flash with an external programmer when the board is bricked or fails to POST. LA-xxxxP numbers follow Compal's ODM scheme, so check the code silkscreened on the PCB, dump and keep the original contents, and verify the image size against the flash chip before writing.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
