thanx guys Im not sure of the difference between win2k and winME. My understanding is that 2k is a lot different (more like NT). If that be the case, then the steps to make it the primary are different and I also understand that those will allow you to set a priority (?). I know win95 used to do that. I still think its a priority thing, but shrug...I dont have the code in front of me to debate it accurately. That is just a guess, but the render times are actual observations. Anyhow, this is all just to help get the times down. Its not really worth the effort if the render is only an hour or so. But, from the start B5 time...a 6 hour render on B4 would be a 7 hour render on B5...but simple changes, you can make it a 20 hour render in B4 a 21 hour render in B5. later BT
