BIOS archive for the HP ProDesk 400 G1 small form factor desktop, with the name referring to the board as Arondite revision A. The file holds the system firmware image used to restore a PC that will not post, is stuck after an interrupted update, or has a corrupted flash. Before writing, read and save the current chip with an SPI programmer, as HP stores serial number and product data in the flash that a donor image may not contain. Check that the board marking matches and that the image size fits the chip.
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.
