Firmware collection for the Toshiba Satellite C55-A series on the PT10F motherboard in its UMA configuration, meaning integrated graphics without a separate GPU. The RAR archive is about 5.71 MB and may contain more than one file, so open it and identify which image is the full flash dump. No board revision or BIOS version appears in the name. Use it to recover a board that does not post after a failed update by programming the SPI chip directly. Confirm the PT10F UMA marking on the PCB, read and keep the original chip contents, and check the image size.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
