HELP: How to change IDE to AHCI mode for Intel P45 mobo Tags: SSD Hard Drives Windows XP Storage Last response: April 18, 2010 7:23 PM in Storage Share cr33d0 April 17, 2010 11:51:14 PM Hi folks, I already installed Win XP in HDD IDE mode and wanted to installed Win 7 Pro in AHCI mode (because I will install the second OS in SSD) in dual boot environment. Since they share the same motherboard, I assume I have to change mobo BIOS to AHCI mode for XP installation in HDD first before I start installing second OS in native Win 7 AHCI driver for SSD. Any workaround on this? (Instead of reinstall XP) My mobo spec: ASUS P5Q - Intel chipset P45 HDD XP installation - Hitachi Deskstar 1 TB SSD for WIn 7 Pro - SSD Vertex 60GB Any advice appreciated. Thanks.
