I would try it because it has worked on Many ASUS boards (NOT just Notebooks) that don't properly change the XSDT/RSDT when flashed.
I created a bootable floppy disk and added aflash2 and your provided modded bios, but nothing done. I can't do with aflash2. I used this commends: First aflash2 /all then nothing done Now i would like to asking to you other thing; when we flash our bios with afudos which commends should we use? Is it true? if not which commend should i use? Thank you! btw sorry for my bad english..
