That's good enough for me. But I wish that some of this stuff was written down someplace, for the benefit of poor ignorant sods like me who are just trying to make their peripherials work. P.S. As we speak, I am typing this on a machine whose root partition is on my shiny new IBM 18GB SCSI drive, with geometry set to 255/63, *and* the 29160N it is hooked up to is (I'm quite sure) set to "Support for disks > 1GB" *disabled*. So if this isn't supposed to work, then somebody please explain to me why it _does_ clearly work.
