When such host-based RAID/AHCI system came in times of Windows XP, there was a way to make it boot Windows with both kinds of BIOS settings. Boot to Windows in a way it normally boots - RAID in your case - and forcibly add a driver corresponding to PCI ids of the controller in ACHI mode, so Windows kernel already has it at boot time.
