Liteon LTC-48161H KH0P UDMA-0

I have upgraded the firmware of LTC-48161H to KH0P. Since then I started getting the message “80 conductor cable not installed” during boot-up. When I connected an 80 conductor cable to the drive, the message stopped and the drive is recognized as UDMA-0 in the BIOS and also in Windows XP. Is something wrong here, because previously the drive was an ultra DMA 33 drive.
