2 # TACPI DControl ACPI module behaviour
6 If the acpi_load variable is set, the ACPI module will be loaded.
7 The use of ACPI can be disabled with:
10 set hint.acpi.0.disabled="1"
12 Note that the ACPI autodetection sets a number of hints to
13 pass information to the ACPI module. These should not be
14 overridden, or system behaviour will be undefined.

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

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