AHCI driver for Win XP 32 bit not working

[DIYspanner]

I'm trying to build a dual boot machine with Win XP 32bit and Win7 64bit.

I've a SATA drive installed with the SATA mode in the BIOS set to AHCI which apparently better than IDE mode.

I downloaded the AHCI driver for the motherboard from Gigabyte, then onto a floppy and when pressing F6 during XP install to select the AHCI driver, XP finds and pick the driver but when all drivers are loaded, XP says it can't see any HDD to proceed with installation.

There are two SATA drivers for XP, one for RAID and one for AHCI

I'd appreciate any opinions - thanks.

XP do not support AHCI disks. What most people do is to install in IDE mode and then force their disk into an ahci mode. But yes you can install in ahci if you have a floppy disk. Firt of all you need to be 100% which chipset is in your mobo. Then download it into a floppy disk and do it again.

Are you aware of this :- AHCI : Enable in Windows 7
"...The issue with AHCI is it needs to be enabled in the BIOS prior to OS installation; doing so after you have installed the OS will disable the PC. The reason why is Windows disables the AHCI drivers not needed during installation. This tutorial will show you how to enable AHCI after you have installed the OS if you didn't already have AHCI enable in the BIOS when you installed the OS..."

See here :- 'Koitsu' says "...Windows Vista and Windows 7 natively have AHCI support (particularly for Intel controllers), while Windows XP lacks it (Intel does provide drivers however)..."
