Hi, WinFast ATA66 PATA PCI controller with popular CMD648 chip. Win7, both x64 & x86 recognize the controller properly. The controller is connected with optical drive working normally in UDMA-2 mode. Unfortunately, the transfer is possible in PIO-4 mode only. How to set the higher modes of data transfer? The drivers for Win7 aren't available on the manufacturer's www page. Regards, f.
