I guess I should have found about about it reading some UDMA66 specs or even that little booklet included with my HDs. Anyway, it *should* be sufficent to connect one of the two drivers to ata1. Then, only one UDMA66 drive is on both ata0 (primary) and ata1 (secondary). The only problem may be that I have heard several times that a secondary IDE port on a mainboard does not neccessarily support all the features as the primary port. I guess I'll simply have to try it out then...
