BIOS image for the Dell OptiPlex 760 desktop, packed in a 2.36 MB RAR archive, with E93839 in the name, which looks like a Dell system board identifier for this model. The name marks the dump as working. A file like this is written to the board SPI flash with a programmer such as a CH341A when the original firmware is corrupted and the machine will not POST. Read and save the existing chip contents before erasing, and check that the image size matches the capacity of the flash chip fitted to your board.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
