Working BIOS for the PT10AN DSC motherboard, revision 2.1, from a version fitted with an AMD processor written as AM5200 in the name. DSC normally marks the discrete-graphics variant of the board. The 4.27 MB RAR should be unpacked and the image compared with the flash capacity on the board before writing. Technicians use such a dump to restore boards that stop posting after a failed update or a corrupted SPI chip. Confirm CPU, graphics variant and PCB revision match, and keep a copy of the original chip contents.
