Because of the increased demand for support of large disks, we are
changing this policy.  SCO XENIX (and SCO UNIX) will support hard
disks having more than 1024 cylinders provided the following three
conditions are met:

- The disk does not have an MS-DOS partition.

- The disk controller supports the required number of cylinders.

- If the disk is the boot device, the kernel, /xenix, must reside
  completely within the first 1024 cylinders.  The safest way to
  avoid this particular problem is to use the area above cylinder
  1023 as your swap area or second file system.

No software changes are necessary, this is the way SCO XENIX currently
behaves.  The release notes are being rewritten for the next release
to include this information.
