I bought a new AM2 motherboard with a Phenom processor. I'm re-using a DVD-ROM and IDE hard drive that is several years old. I'm about to install Windows XP and I was wondering if I can enable AHCI now even though I don't have any SATA hard drives yet. I've read on the internet that it's better to enable AHCI before a Windows XP install then after.
However, I don't have any SATA drives installed yet, but I plan to buy one soon (ie: few weeks).
Should I set AHCI before installing Windows XP?
