# Tset Snum_ide_disks DSet the number of IDE disks
NOTE: this variable is deprecated, use root_disk_unit instead.
set num_ide_disks=<value>
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.
set root_disk_unit=<value>
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.
