BIOS archive for a Dell OptiPlex 790 desktop, 4.80 MB in RAR form. The name adds I3, which most likely means it was taken from a unit fitted with a Core i3 processor; no board revision or chip type is given. A repair shop uses this kind of dump to rewrite the SPI flash on a system that will not POST or has corrupted settings. Since Intel platforms keep ME and other regions in the same image, read and keep your own chip contents before programming, and compare sizes first.
