Hi, I too observe this message on an ATA-100 capable motherboard with an ATA-66 compliant cable. I ascribe the error to the fact that although the master IDE drive is ATA-66, my secondary CD-ROM drive (on the same controller) is operating in PIO Mode 4. I'm not sure whether the CD-ROM drive is UDMA-capable and is simply set to use PIO in the BIOS. The next time I have to reboot the system I will check. I don't know whether there is a single-device-per-channel limit on ATA-66 operation. If this were the case, it seems odd that ATA-66 cables are made with multiple connection points.
