Hey guys, I've asked this within other semi-related threads, and didn't get a lot of bites. Mods, if there's a problem with posting this, feel free to delete... When I got my P-7811 about a month ago, I tried to like Vista (for the second time), but I really hated it. I completely reformatted and threw on XP Pro SP3. I managed to get everything working, including the audio and cam mic, which i was/am thrilled about. What I FORGOT to do was install the drivers at install for AHCI, so now I'm stuck at IDE. So question is: Is there any way to get the drivers installed for AHCI after install of XP? Thanks much in advance!
