WinFast ATA66 - CMD648 - PATA controller

The PCI PATA WinFast ATA66 controller (CMD648 chip) is recognized and works, but in PIO-4 mode only. How to unable UDMA-2 (or higher) mode in both 32 and 64-bit versions on Windows 7? The same hardware (mainboard, PCI controller, optical drive connected to the WinFast ATA66) is fully functional under linux.
