Those machines were running that card plus three Sample cell cards in different houses even. I believe I tried other PCI cards to compare. My feeling is there is a voltage drop on boot perhaps. One SC card would boot no video every few boots, 2 Cards more often, 3 cards more often still. It began with two new identical Dual 867 MDDs, I swapped a Radeon from my Dual 1.25 MDD and then the 867 did fine, but the 1.25 had the same problem with the Nvidea. OS9 we're talking here. I've now overclocked both to 1ghz and installed Radeons with no problems. MDD.... I was browsing here to find a category in which to pose this curious phenomena when I came across your post. But I'm glad to hear the Nvidea is doing you well. These are fabulous machines for MIDI.
