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.
