Firmware set for the Dell 5580, Compal board LA-E152P revision 1.0, with the reference designators UC5, UT2 and UT6 in the name. These likely mark separate chips on the board, such as the BIOS flash and other programmable parts, so the archive probably holds several dumps. Check each designator against the boardview before writing. LA-xxxxP is Compal numbering. Back up every original chip with a programmer, confirm image sizes match chip capacities, and expect the service tag to need restoring.
