ASUS P8Z77-V desktop motherboard BIOS, for board revision 1.02, marked as a working image and stored in a RAR archive of around 4 MB. The revision is printed on the PCB and should match before flashing. Technicians use such a file to reprogram the SPI BIOS chip with an external programmer when a board fails to post after a bad update. ASUS boards keep the MAC address and serial in the flash, so back up the original chip and restore those details if needed, and confirm 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.
