BIOS firmware archive for the Dell OptiPlex 9020 All-in-One desktop, with IPPLP-AZ in the name, which appears to be the system board designation. The RAR package of about 6.7 MB should hold an SPI flash image meant for writing with a hardware programmer such as a CH341A when the machine is dead or the firmware is corrupted. Before flashing, read and save the original chip contents, since they hold the service tag and other unique data, and confirm the image size matches the capacity of the flash chip on the 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.
