I have used your modded sata-drivers many times on my ICH8-R motherboard when installing 32 bit versions of Windows XP and Windows 7. However, just now I wanted to give Windows 7 64 bit a go because I've added more ram, but the installer won't recognize the modded 64 bit driver. Is there any obvious reason for this that I am missing? Also, there seems to be newer sata drivers available from Intel than the ones, you presently have modded. Care to mod the new ones for us? :-) Thanks.
