We have a machine here in the lab that is the precurser of your machine that we also had boot problems with. What I found was that the adaptec BIOS Disks > 1GB support was breaking the linux and FreeBSD boot routine. When I disabled Disks > 1GB my problems were solved. It seems the BIOS setting is for machines running OSes that need help looking at large disks. I hope this helps. If you already have your machine working great; I hope this my help someone else then. james On Tue, 8 Aug 2000, Daniel Lang wrote: > Hi, > > we've got a Dell PowerEdge 6100/200 here, which is an older > SMP server, featuring 4 PPro 200 CPU's two internal AIC7880 > channels and an Adaptec 2940UW PCI controller.
