BIOS firmware for the PIG41R board, Wistron number 08174-1 with code 3AG01, supplied as a 603 KB RAR. Wistron's five-digit board numbering should be printed on the PCB, and matching it is the first check before flashing. The image is used to rewrite a corrupted or empty SPI flash chip with an external programmer when the system shows no video or loops at power-on. Keep a backup of the original chip contents, and make sure the dump size equals the flash chip 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 @afsbiosfree. Enginerys does not host this file.
