+
+	When booting from a SCSI disk on a system with one or more IDE disks,
+	and where the IDE disks are the default boot device, it is necessary
+	to tell the kernel how many IDE disks there are in order to have it
+	correctly locate the SCSI disk you are booting from.

+# Tset Sroot_disk_unit DForce the root disk unit number.

+
+	If the code which detects the disk unit number for the root disk is
+	confused, eg. by a mix of SCSI and IDE disks, or IDE disks with
+	gaps in the sequence (eg. no primary slave), the unit number can be
+	forced by setting this variable.
