ASUS archive of about 38.1 MB whose name describes disabling onboard RAM, without naming a model or board. It most likely holds modified BIOS images or tools that let a laptop with faulty soldered memory boot from the SO-DIMM slot only. Check the contents and match any image to your exact model and board revision. Back up the original flash before writing anything. Treat it as a workaround that skips the failed memory chips, not as a repair of them.
