-This file lists the possible command line options that can be used to tweak
-the boot process of this CD. This lists the Gentoo-specific options, along
-with a few options that are built-in to the kernel, but that have been proven
-very useful to our users. Also, all options that start with "do" have a "no"
-inverse, that does the opposite. For example, "doscsi" enables SCSI support
-in the initial ramdisk boot, while "noscsi" disables it.

-Hardware options:
-
-acpi=on This loads support for ACPI and also causes the acpid daemon to
- be started by the CD on boot. This is only needed if your
- system requires ACPI to function properly. This is not required
- for Hyperthreading support.
-acpi=off Completely disables ACPI. This is useful on some older systems,
- and is also a requirement for using APM. This will disable any
- Hyperthreading support of your processor.
-console=X This sets up serial console access for the CD. The first
- option is the device, usually ttyS0 on x86, followed by any
- connection options, which are comma separated. The default
- options are 9600,8,n,1.
-dmraid=X This allows for passing options to the device-mapper RAID
- subsystem. Options should be encapsulated in quotes.
-doapm This loads APM driver support. This requires you to also use
- acpi=off.
-dobladecenter This adds some extra pauses into the boot process for the slow
- USB CDROM of the IBM BladeCenter.
-dopcmcia This loads support for PCMCIA and Cardbus hardware and also
- causes the pcmcia cardmgr to be started by the CD on boot.
- This is only required when booting from a PCMCIA/Cardbus device.
-doscsi This loads support for most SCSI controllers. This is also a
- requirement for booting most USB devices, as they use the SCSI
- subsystem of the kernel.
-hda=stroke This allows you to partition the whole hard disk even when your
- BIOS is unable to handle large disks. This option is only used
- on machines with an older BIOS. Replace hda with the device
- that is requiring this option.
-ide=nodma This forces the disabling of DMA in the kernel and is required
- by some IDE chipsets and also by some CDROM drives. If your
- system is having trouble reading from your IDE CDROM, try this
- option. This also disables the default hdparm settings from
- being executed.
-noapic This disables the Advanced Programmable Interrupt Controller
- that is present on newer motherboards. It has been known to
- cause some problems on older hardware.
-nodetect This disables all of the autodetection done by the CD, including
- device autodetection and DHCP probing. This is useful for doing
- debugging of a failing CD or driver.
-nodhcp This disables DHCP probing on detected network cards. This is
- useful on networks with only static addresses.
-nodmraid Disables support for device-mapper RAID, such as that used for
- on-board IDE/SATA RAID controllers.
-nofirewire This disables the loading of Firewire modules. This should only
- be necessary if your Firewire hardware is causing a problem with
- booting the CD.
-nogpm This diables gpm console mouse support.
-nohotplug This disables the loading of the hotplug and coldplug init
- scripts at boot. This is useful for doing debugging of a
- failing CD or driver.
-nokeymap This disables the keymap selection used to select non-US
- keyboard layouts.
-nolapic This disables the local APIC on Uniprocessor kernels.
-nosata This disables the loading of Serial ATA modules. This is useful
- if your system is having problems with the SATA subsystem.
-nosmp This disables SMP, or Symmetric Multiprocessing, on SMP-enabled
- kernels. This is useful for debugging SMP-related issues with
- certain drivers and motherboards.
-nosound This disables sound support and volume setting. This is useful
- for systems where sound support causes problems.
-nousb This disables the autoloading of USB modules. This is useful
- for debugging USB issues.

Volume/Device Management:
-
-dodevfs This enables the deprecated device filesystem on 2.6 systems.
- You will also need to use noudev for this to take effect.
- Since devfs is the only option with a 2.4 kernel, this option
- has no effect if booting a 2.4 kernel.
-doevms2 This enables support for IBM's pluggable EVMS, or Enterprise
- Volume Management System. This is not safe to use with lvm2.
-dolvm2 This enables support for Linux's Logical Volume Management.
- This is not safe to use with evms2.
-noudev This disables udev support on 2.6 kernels. This option requires
- that dodevfs is used. Since udev is not an option for 2.4
- kernels, this options has no effect if booting a 2.4 kernel.
-unionfs Enables support for Unionfs on supported CD images. This will
- create a writable Unionfs overlay in a tmpfs, allowing you to
- change any file on the CD.
-unionfs=X Enables support for Unionfs on supported CD images. This will
- create a writable Unionfs overlay on the device you specify.
- The device must be formatted with a filesystem recognized and
- writable by the kernel.
-
+doevms This enables support for IBM's pluggable EVMS, or Enterprise
+ Volume Management System. This is not safe to use with lvm2.
+dolvm This enables support for Linux's Logical Volume Management.
+ This is not safe to use with evms2.
Other options:
-
-debug Enables debugging code. This might get messy, as it displays
- a lot of data to the screen.
-docache This caches the entire runtime portion of the CD into RAM, which
- allows you to umount /mnt/cdrom and mount another CDROM. This
- option requires that you have at least twice as much available
- RAM as the size of the CD.
-doload=X This causes the initial ramdisk to load any module listed, as
- well as dependencies. Replace X with the module name. Multiple
- modules can be specified by a comma-separated list.
-noload=X This causes the initial ramdisk to skip the loading of a
- specific module that may be causing a problem. Syntax matches
- that of doload.
-nox This causes an X-enabled LiveCD to not automatically start X,
- but rather, to drop to the command line instead.
-scandelay This causes the CD to pause for 10 seconds during certain
- portions the boot process to allow for devices that are slow to
- initialize to be ready for use.
-scandelay=X This allows you to specify a given delay, in seconds, to be
- added to certain portions of the boot process to allow for
- devices that are slow to initialize to be ready for use.
- Replace X with the number of seconds to pause.
