If the system boots and works then leave it alone. That is a strange setup but should be fine. Yes the cable should be an 80-wire cable. if you run a test hdparm -t /dev/hdx replace hdx with your hard drive letter and get >16 megabytes per second udma is active. If it is not then run hdparm -d1 /dev/hdx then run the hdparm -t /dev/hdx your system board will either give you 2-3 times the drive speed or Linux will shut down dma if it is not reliable.
