Micronics do dual (and quad) Pentium/PPro motherboards, which are PCI/(E)ISA configured. Indeed, my personal SMP experimentation machine (though not my 'real' SMP machines) have 3COM EISA cards in them for management interfaces (the 'real' work going out through PCI cards). Fortunately, the 3c579 Vortex is bus-mastering, so would appear to be unaffected by the suggested changes here (please correct me if I'm wrong here -- when it comes to hardware, I'm more of a Sun (so sue me :) person than PC). However, the point remains that until somebody figures out a totally PCI-based motherboard (7-8 PCI slots), we *cannot* afford to completely blow away EISA support, as you would seem to suggest. -aDe -- Ade Lovett, Demon Internet Ltd.
