# 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.
