Working BIOS for the Dell OptiPlex 5055 Ryzen desktop. The name carries version 1.8.0, labelled CPU1.8.0, and marks the dump as fully working. Packed in a 5.31 MB RAR, it is meant for programming the SPI flash chip of this AMD board when the system will not start. Check that the flash capacity matches the image, and dump the original first so the service tag and system data are kept. A clip-on programmer usually works, but desoldering the chip gives a more reliable read and write.
