I have an ABIT mobo and have some new IDE cables. The mobo has 40 pins on its IDE connectors but my HDD, CDROM, Floppy and IDE cables have a pin missing to help figure out the orientation.

Both have 40 pin connectors, but they function differently.<P>ATA33 cables are adequate for ATA33 drives. ATA66/100 cables are fine for all drives, expcept maybe the ATA133 drives now out.
