BIOS package for the Dell OptiPlex 7090 desktop, provided as a 26 MB RAR archive. No board number, revision or version is stated, so inspect the contents to see whether it holds a full SPI dump or a vendor update file. Full dumps are written with an external programmer to recover a dead or corrupted system, while update executables are run from the OS or BIOS menu. Back up the original chip before writing, and make sure any image matches the flash chip size and layout.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
