BIOS firmware for an A4310 all-in-one computer, marked as Working in the name, packed as a 4.28 MB RAR. The brand is not given, so confirm the model and board markings on the actual machine before use. A tested dump is used to rewrite the SPI flash with an external programmer when the system will not post or the firmware is corrupt. Read and save the original chip contents first, and check that the image size matches the flash capacity before writing.
