acpi=on ACPIサポートを有効にし、ブート時にCDがacpidデーモンを起動するようにします。これは、ACPIが正しく機能することが、システムによって要求されている場合にのみ必要になります。ハイパースレッディングのサポートのために必要にはなることはありません。
acpi=off ACPIを完全に無効化します。このオプションは古いシステム上で起動するために使えるほか、APMを使うための要件でもあります。このオプションはハイパースレッディングのあらゆるサポートを無効化します。
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 also requires that acpi=off.
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 PCMCIA/Cardbus devices.
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.
sda=stroke This allows the user to partition the whole hard disk even when the BIOS is unable to handle large disks. This option is only used on machines with an older BIOS. Replace sda with the device that requires 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 the system is having trouble reading from the 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 disables 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 used if the 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.
slowusb This adds some extra pauses into the boot process for slow USB CDROMs, like in the IBM BladeCenter.
Logical volume/device management
dolvm This enables support for Linux's Logical Volume Management.
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 the user to umount /mnt/cdrom and mount another CDROM. This option requires that there is 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.
dosshd Starts sshd on boot, which is useful for unattended installs.
passwd=foo Sets whatever follows the equals as the root password, which is required for dosshd since the root password is by default scrambled.
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.
nonfs Disables the starting of portmap/nfsmount on boot.
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 the user 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.
