BIOS image for the ASUS Maximus VII Hero motherboard, revision 1.01, with PU1 in the name. PU1 likely refers to the flash chip position, since this board carries more than one BIOS chip, but that is not confirmed. The 5.99 MB RAR is marked working. Desktop owners and technicians use such a dump to restore a corrupted chip with an external programmer when a USB flashback fails. Save the original chip contents first, confirm the revision, and make sure the file matches the chip size.
