| # Tset Snum_ide_disks DSet the number of IDE disks |

| |
| 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. |
