Hard disks with > 1024 Cylindars

[Mark Dornfeld]

I have purchased a Wren VI Harddisk for installation under SCO Xenix
and/or SCO Unix ODT.  The disk has 1747 cylindars, 7 head and 54
sectors/track.  I am using an Everex ESDI controller that understands
what this disk is all about and has routines to handle it.

The SCO ODT documentation suggests that such a disk is compatible as
long as the root partition doesn't cross over the 1024 cylindar
boundary.  Now, my limited understanding of disk geometry tells me
that is not an easy task.  

Has anyone had any experience with this or similar drives under Xenix
or Unix.  Can it be used reliably?
