T420 Dual Boot Trouble 7 & XP

Options

‎10-27-2011 01:52 PM

I have a Think Pad T420 with dual boot option of Windows 7 Pro and Windows XP Pro both 32-bit. However for me to boot into Windows 7 I have to set the SATA configuration in the BIOS to AHCI Mode, but that will cause the XP to BSOD with the error of unable to detect hard drive. I change the SATA configuration to Compatibility and Windows XP can boot successfully but Windows 7 BSOD with the same error. I cannot seem to find the right driver for the AHCI chipset for Windows XP. If anyone could offer any assitance, that would be great.

It'll be the Intel Rapid Storage drivers for XP to work in AHCI mode.
