The 274x cards only have one controller (aic7770) and the twin channel 274xT has two SCSI busses (channels). The 3940 adapters have two physically separate controllers (aic7870) which should be found as separate devices by the PCI probe. Thus, the two "channels" on the 3940 is like having two 2940 cards in your box. Dan Eischen deischen@iworks.InterWorks.org
