+grml findiso=/grml_2010.04.iso Look for the specified ISO file on all disks where it usually
+ looks for the .squashfs file (so you don't have to know the device name
+ as in isofrom=....).
+grml fetch=$IP/filename.squashfs Download a squashfs image from a given url, copying to ram and booting it.

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
+that requires a password manually. There are no default passwords on
+the live system - all accounts are LOCKED by default for security reasons.
+Instead just invoke the script grml-lock which prompts for setting a
+password.
