Small 234 KB zip for the P4i45GV motherboard, revision 5.0 according to the name. The model string points to an Intel 845GV-class desktop board, though the archive name says nothing about its exact contents, which could be a BIOS image or service material. Boards of this age often use a parallel or FWH flash chip rather than SPI, so check the chip type and programmer support, save the original contents, and make sure the revision on the PCB is 5.0 before relying on the file.
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 @laptopchiplevelrepair. Enginerys does not host this file.
