-grml2ram Copy grml's squashfs file to RAM and run from there
+grml2ram Copy Grml's squashfs file to RAM and run from there
grml toram Copy the whole CD/medium to RAM and run from there
grml toram=filename.squashfs Copy the specified file to RAM and run from there
Usage example: grml toram=grml-medium.squashfs
Notice: grml2ram is an alias for this option which
corresponds with the grml flavour settings by default
-grml tohd=/dev/sda1 Copy grml's squashfs file to harddisk partition for later
+grml tohd=/dev/sda1 Copy Grml's squashfs file to harddisk partition for later
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
"boot=live isofrom=/dev/sda1/grml.iso"
Notice: "fromiso" does the same as "isofrom", it's just there
to prevent any typing errors
-grml findiso=/grml_2009.10.iso Look for the specified ISO file on all disks where it usually
+grml findiso=/grml_2010.04.iso Look for the specified ISO file on all disks where it usually

+grml fetch=$IP/filename.squashfs Download a squashfs image from a given url, copying to ram and booting it.
+ Due to current limitations in busyboxs wget and DNS resolution, an URL

grml live-media-path=live Sets the path to the live filesystem on the medium
By default, it is set to /live
grml module=grml Instead of using the default "$name.module" another file can

grml swraid Enable automatic assembling of software raid arrays
+grml nodmraid Do not enable present dmraid devices.
+grml dmraid=on Automatically enable any present dmraid devices.
+grml dmraid=off Actively try to stop any present dmraid devices.
grml nolvm Disable scanning for Logical Volumes (LVM)
grml lvm Automatically activate Logival Volumes (LVM) during boot
grml readonly Make sure all harddisk devices (/dev/hd* /dev/sd*) are forced to read-only mode
Additional notes:
-----------------
-*) Try "grml pci=irqmask=0x0e98" if (you have a notebook and) your
-PS/2 mouse doesn't work. (Possibly caused by a BIOS-flaw on your board,
-BIOS updates can help.) Sometimes, switching to the text console with
-Control-Alt-F1 and back to the X-screen with Control-Alt-F7 solves the
-problem without rebooting, since the X server reinitializes the mouse
-driver during that procedure.

+*) If your Grml-CD makes strange noises during boot, or you see frequent
errors like "squashfs: read error", or programs are crashing randomly,
then your CD image is probably defective or incomplete, your CD-burner
created a defective CD due to wrong writing speed or bad media or your
directory live, containing the squashfs compressed filesystem file,
must be located in the top level directory of the CD.
-*) Caution: screensavers: Don't start xlock/vlock or any other screensaver
-that requires a password. There are no default passwords on grml,
-i.e. all accounts are LOCKED unless you explicitly set a password.
-See also README.txt about this issue.
-Hint: If you accidentially started a screensaver switch to one of the
-textconsoles by Control-Alt-F1 and kill the screensaver (or just set a
-password for the grml user). Take a look at the script grml-lock.
+*) Caution: screensavers: Don't start vlock or any other screensaver

+Instead just invoke the script grml-lock which prompts for setting a
+password.
