The following boot options can be combined.
------------------
grml lang=at|de|cn|da|es|fr|it Specify language ($LANG, $LC_ALL, $LANGUAGE - utf8) + keyboard
grml lang=nl|pl|ru|sk|tr|tw|us Specify language ($LANG, $LC_ALL, $LANGUAGE - utf8) + keyboard
-grml lang=$LANG-iso Activate $LANG (use like in lines above) with iso-mode instead of utf8
-grml gmt Use GMT-based time (UTC=yes)
-grml utc Use Coordinated Universal Time (UTC=yes)
-grml localtime Use local time (UTC=no)
-grml tz=Europe/Vienna Use specified timezone for TZ
-grml keyboard=us xkeyboard=us Use different keyboard layout (text-console/X)
+grml utc Hardware Clock is set to Coordinated Universal Time (UTC)
+grml localtime Hardware Clock is set to local time (LOCAL), this is the default
+grml tz=Europe/Vienna Use specified timezone for TZ, defaults to TZ=UTC
+grml keyboard=us Use different keyboard layout
Configuration settings:
-----------------------
use via "grml bootfrom=/dev/sda1"
grml bootfrom=/dev/sda1 Use the squashfs file from directory 'live' of the specified device
Setup can be done booting 'grml tohd=/dev/sda1' or
- running 'rsync -a --progress /lib/live/mount/medium/live /media/sda1/'
+ running 'rsync -a --progress /run/live/medium/live /media/sda1/'
grml bootfrom=removable Restrict search for the live media to removable type only.
grml bootfrom=removable-usb Restrict search for the live media to usb mass storage only.
-grml isofrom=/dev/sda1/grml.iso Use specified ISO image for booting
- Useful when booting as a rescue system from harddisk - just boot
- the according grml kernel and initrd using the bootoptions
- "boot=live isofrom=/dev/sda1/grml.iso"
+grml isofrom=[fs:][/device]/grml.iso Use specified ISO image for booting.
+ Useful when booting as a rescue system from a different device.
+ If you want to load the image from a device different from the root device
+ specified through the bootloader, prefix its device path to the path, like
+ in "/dev/sda1/grml.iso".
+ Internally, the initrd will mount the given device, automatically detecting
+ the file system.
+ If needed, prefix the file system separated with a colon character to
+ override the automatic detection, like in "reiserfs:/dev/sda1/grml.iso".
+ As an example, boot the according grml kernel and initrd using the
+ bootoptions "boot=live isofrom=btrfs:/dev/vda40/path/to/grml.iso"
Notice: "fromiso" does the same as "isofrom", it's just there
to prevent any typing errors
grml findiso=/grml_2010.12.iso Look for the specified ISO file on all disks where it usually
grml welcome Welcome message via soundoutput
grml noeject Do NOT eject CD after halt/reboot
grml noprompt Do NOT prompt to remove the CD when halting/rebooting the system
-grml distcc=$NETWORK,$INTERFACE Activate distcc-daemon to listen on specified network
- and interface, usage example:
- distcc=192.168.0.1/24,eth0
-grml gcc=3.4 gpp=3.4 Link /usr/bin/gcc, /usr/bin/cpp and /usr/bin/c++ to specified version
grml startx{=windowmanager} Start X window system automatically
Default window manager (if not provided): wm-ng (wrapper around fluxbox)
grml nostartx If using startx as default bootoption the nostartx *disables* automatic
initiated from the VNC server instead of the VNC client. Has to be
combined with the vnc bootoption.
[Note: Grml 2011.12+ doesn't include a VNC client.]
+grml getfile.retries=$NUM Retry the download of the files specified in the netconfig=... +
+ netscript=... options up to $NUM times
+
Accessibility related settings:
-------------------------------
grml xmodule=ati|fbdev|i810|mga Use specified X.org-Module (1)
grml xmodule=nv|radeon|savage|s3 Use specified X.org-Module (2)
grml xmodule=radeon|svga|i810 Use specified X.org-Module (3)
-grml no{acpi,agp,cpu,dhcp} Skip parts of HW-detection (1)
-grml no{dma,fstab,modem} Skip parts of HW-detection (2)
-grml no{pcmcia,scsi,swap,usb} Skip parts of HW-detection (3)
+grml no{acpi,cpu,dhcp,fstab,swap} Skip parts of HW-detection
grml blacklist=modulename[,module2] Completely disable loading of specified module(s) via
blacklisting through udev's /etc/modprobe.d/grml
-grml fwtimeout=50 Set firmware timeout via /sys/class/firmware/timeout to specified value
grml nosound Mute sound devices (notice: this does not deactivate loading of sound drivers!)
grml vol=number Set mixer volumes to level $number
grml micvol=number Set mixer volume of microphone to level $number (default: 0)
-grml pnpbios=off No PnP Bios initialization
grml acpi=off Disable ACPI Bios completely
-grml nofirewire Disable initialization of firewire devices in booting sequence
grml pci=irqmask=0x0e98 Try this, if PS/2 mouse doesn't work *)
grml pci=bios Workaround for bad PCI controllers
-grml ide2=0x180 nopcmcia Boot from PCMCIA-CD-ROM (some notebooks)
-grml mem=128M Specify Memory size in MByte
grml libata.force=[ID:]VAL Force configurations for libata.
Usage example: grml libata.force=1:pio4
to force pio4 mode on device "ata1:00:"
grml noagp noapic acpi=off nodma
to skip some critical parts of the autodetection system.
-*) Some boards (especially those with E-ISA slots) apparently don't pass
-the proper memory size to the linux-kernel. It may cause the message
-"Panic: cannot mount root file system" and the system hangs. Use "grml
-mem=128M" to solve that problem if your system has 128MByte memory for
-example (caution: you MUST use a capital "M" here).
-
*) The "myconfig=/dev/partition" option allows you to reconfigure the
system after autoconfiguration by running a bourne shell script called
"grml.sh" and/or extracting configuration files from a file named
projects / grml-live.git / blobdiff
