BIOS firmware for the Toshiba Satellite C850, with the name noting a D1R designation and a Pegatron-made motherboard, packed in RAR. Pegatron is the ODM behind several C850 board versions, and the D1R token appears to identify which one. Since no full board number is given, compare the markings on your PCB carefully. Use the image to reprogram a corrupted SPI flash with an external programmer. Keep a backup of the original chip and confirm the image size matches its capacity.
