BIOS firmware for the Toshiba Satellite C55-A laptop on a PT10F board, UMA variant, meaning integrated graphics without a discrete GPU, packed as a 5.71 MB RAR file. PT10-series boards come from Pegatron, which manufactured these Satellite models. Use the dump to rewrite the SPI flash chip with a programmer when the laptop shows no image, loops on power or suffers corrupted firmware. Do not flash it onto a discrete-graphics board, confirm the board code on the PCB, back up the original chip and check that the image size fits the flash.

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 →
