The machine actually has 4G of RAM, so I don't know where the 5G number is coming from - is that expected for some reason? Once the system is booted, top(1) shows 4G of RAM in use, so I believe the end result is correct. I'll have a test machine here for a while, so I can provide followup information if it will be helpful. -- Bill Moran Collaborative Fusion Inc. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: State-Changed-From-To: open->closed State-Changed-By: linimon State-Changed-When: Thu Mar 9 00:26:30 UTC 2006 State-Changed-Why: Misfiled followup to i386/79779; content migrated.
