BIOS archive for the ASUS P8H61-M LX desktop board, revision 1.01, in RAR format at 2.26 MB. The file name gives no firmware version, so look at the contents to see which BIOS build is included. A technician would use it to rewrite the SPI flash chip on a board that does not POST because of damaged firmware, typically with a USB programmer and clip. Read and keep a copy of the existing chip before writing, confirm the board is revision 1.01, and make sure the image size equals the chip capacity.
