BIOS file for the HP All-in-One 24-df0008ur desktop, packed as a 7.2 MB rar. The name gives the exact product model but no motherboard number, chip size or version, so look inside the archive before flashing. All-in-one boards keep their firmware on an SPI flash that can be read and written with a CH341A or similar programmer when the unit no longer powers on or POSTs. Back up the original chip before writing, since HP stores serial numbers and product data in the image, and check that the dump size matches the flash capacity.
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.
