IE: 1 driver per IDE interface. Using IBM 10 gig drives, 2 drives goes quite a long ways. I'd imagine that buying a PCI EIDE board for channels 3 and 4 would be of some benefit for a 'server' that doesn't need the IRQs for anything else. Not the greatest performance solution, but quite a bit of bang for the buck. -- | Matthew N.
