    Hi,

    I have a Dell Studio 1555 laptop. I installed XP SP3 fresh from scratch, and I had to set AHCI to IDE in the BIOS in order for the install to complete. I finished the XP install and installed Dell drivers for video, wireless & LAN. When I go into BIOS again and re-enable AHCI, Windows does not boot up. I get a few lines that flash on the screen that I can't read and it reboots. If I turn AHCI back to IDE it boots up normally. How can I get AHCI turned back on after having installed XP?

    Thanks

    You cant if you want to stay with xp. to run windows xp correctly it has to be in the IDE mode. in most cases AHCI is used only for the vista and windows 7 operating systems. if you try to change it back and run xp it will blue screen on you or wont boot at all.unless a computers BIOS only has one setting and theres no other choices listed then and only then can you use the AHCI mode to run xp, vista or windows 7 equally well with no glitches.
