BIOS firmware archive for HP board 6050A2566302-MB-A04, revision A04, compressed to 8.99 MB. This Inventec-style PCB number is printed on the motherboard, and the revision suffix should match exactly before the image is trusted. Unpack the zip to check how many images it holds and their sizes, then write the correct one to the SPI flash using a hardware programmer. Read and archive the original contents first so the serial number and product data can be restored afterwards.
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 @ComputerBIOSBinFile. Enginerys does not host this file.
