RAR archive of 1.15 MB labelled PLF, PLR, CSF and CSR UMA MB, which suggests motherboard material for several related platforms with integrated graphics only, UMA meaning unified memory architecture with no discrete GPU. The brand and board number are not stated, so open the files and look at title blocks or labels to identify them. Material of this kind is typically used to trace power rails and signals or locate components; make sure the platform code on the PCB matches before relying on it.
