i plan on installing win7 64bit on a new machine and i want to be sure that i have AHCI enabled for hot swapping SATA drives. can i do thid in the BIOS before i even install the OS or during the install? i have read how to enable AHCI after installing but wondeded if it could be done before. thanks
Yes, it can be done. I enable it in the BIOS first before the install.
In the Windows 7 install screen where it shows the partitions, etc., you'll see an option to "Load Drivers" click that and a be sure you have a thumb drive or external hard drive plugged in prior to boot up.
Select the drive you have the SATA or AHCI driver folder on and click on it, then they should install. With Intel drivers, these will be in separate folders for "Floppy x86" and "Floppy x64", these are the drivers for AHCI. The Windows 7 will automatically load the proper driver for the chipset being used.
As far as AMD drivers, I'm not sure.
