BIOS dump for the Dell OptiPlex 3070 on the IPCFL-CG board, marked as 100% working and supplied in a 6.75 MB RAR. A raw image of this kind is written to the motherboard SPI flash with a programmer such as a CH341A or RT809H when the desktop fails to POST or a BIOS update was interrupted. Before writing, read and keep the existing chip contents, since Dell stores the service tag and other system data in the flash, and confirm the image size matches the chip.
