BIOS image for the ASUS P8H61-M LE motherboard, version 4501 with CSM in the name, intended for a 4 MB flash chip, in a 3.03 MB RAR archive. The CSM label marks the ASUS Corporate Stable Model line of this Intel H61 board. Use it to reprogram the SPI chip with an external programmer when the board does not post. Check that the chip installed is indeed 32 Mbit, read and save its original contents first, and compare the board revision on the PCB with the file before writing.
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.
