- knoppix knoppix_dir=KNOPPIX Directory to search for on the CD.
- knoppix knoppix_name=KNOPPIX Cloop-File to search for on the CD.
- knoppix testcd Check CD data integrity and md5sums
- expert Interactive setup for experts
-
- NEW Kernels and Options in version 3.4:
- knoppix26 [Options...] Boots with Kernel 2.6 (2.4 is default)
- expert26 [Options...] Same for expert mode
- knoppix26 acpi=off Disable ACPI configuration in Kernel 2.6
- memtest Run memtest86 instead of Linux
-
- Hint: Using the default DE-bootimage, SYSLINUX boots with german keyboard
- layout. The '=' letter is located at Shift-0 on this keyboard (just in
- case you want to change keyboard and language with lang=us).
-
- *) Try "knoppix 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-F5 solves the
- problem without rebooting, since the X server reinitializes the mouse
- driver during that procedure.
-
- **)
- You can also have your own splash-screen in putting an executable shell-
- script to /cdrom/KNOPPIX/splash.sh. For an example how to do this see:
- /usr/bin/splash-knoppix.sh. (Feature added by Fabian Franz.)
-
- ***) Bootfrom needs access to a running Knoppix-System with the same Kernel
- as the Bootkernel, before it is able to mount the partition / ISO-Image.
- This should allow a poor mans install from NTFS-Partitions and makes it
- also possible to boot an ISO-Image directly. You can also use wildcards
- in the ISO-Filename, but it must be unique. So: If you have just one
- KNOPPIX.iso on /dev/hda1 you can access it as: bootfrom=/dev/hda1/K*.iso,
- but if there are several, you need to make clear, which one you want.
- (Feature added by Fabian Franz.)
-
- If your KNOPPIX CD makes strange noises during boot, or you see
- frequent errors like "cloop: read error", or programs on your KDE
- desktop keep crashing randomly, then your CD image is probably defective
- or incomplete, or your CD-burner created a defective CD due to wrong
- writing speed or bad media. This is the most common error reported.
- Please boot with "knoppix testcd" to check if the CD is OK, and/or even
- better, verify the MD5 checksums that are present on the mirrors before
- writing the CD. In some cases, defective IDE controllers cause this
- error if you have DMA enabled. Also, please read the KNOPPIX-FAQ.
-
- In case of a failing hardware autodetection, try booting with any of
- the "no-" options as shown in the table above, like in
- knoppix noagp noaudio noapm noapic acpi=off nodma nopcmcia noscsi nousb
- to skip some critical parts of the autodetection system.
-
- The "noswap" option is useful for a forensic analysis without touching
- existing swap partitions.
-
- Some Boards 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 "knoppix mem=128M" to solve that
- problem if your system has 128MByte memory for example (caution:
- you MUST use a capital "M" here).
-
- The "expert" mode provides a very simple interface to loading additional
- Kernel modules from floppy disks (ext2 or vfat), plus interactive
- configuration of mouse/keyboard/soundcard/xserver. "expert" mode supports
- the same boot options as "knoppix".
-
- The "floppyconfig" or "(my)config=/dev/partition" options allow you to
- reconfigure the system after autoconfiguration by running a bourne
- shell script called "knoppix.sh" from the root directory on the given
- device (or floppy). There is a GUI to create such a configuration
- floppy disk calles "saveconfig" (also located in the KDE menu under
- "KNOPPIX", but experts also know how to do this by creating their own
- shellscripts. From Version 2.1 and up, a file called "knoppix.sh", if
- located in the toplevel KNOPPIX directory on CD, will also be executed
- at startup. This makes ist easier to create customized versions without
- having to change anything on the compressed filesystem KNOPPIX/KNOPPIX.
-
- SCSI-Emulation is active for all CD-Roms (unless you switch it off by
- using the "atapicd" option), so IDE CD-Writers should work with the
- installed versions of cdrecord and cdrdao (or the graphical frontends
- thereof, k3b for example).
-
- If your BIOS does not support el torito booting from CD, you can create
- two bootable floppy disks by issuing (from Knoppix running on a different
- machine) the command "mkbootfloppy", which will create a bootable
- Kernel-disk plus a disk containing the initial ramdisk, which will be
- prompted for at boottime.
-
- If you wish to remaster the CD, please don't forget to specify
- -no-emul-boot -boot-load-size 4 -boot-info-table \
- -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat
- as option to mkisofs. Otherwise your CD won't be bootable. The
- directory KNOPPIX, containig the compressed filesystem file "KNOPPIX",
- must be located in the top level directory of the CD.
-
- Caution: X-Screensaver: Don't start xlock or any screensaver that
- requires a password. There are no default passwords on KNOPPIX,
- i.e. all accounts are LOCKED unless you explicitly set a password.
- See also README_Security.txt about this issue.
- If you accidentially hit the screensaver button in KDE,
- switch to one of the textconsoles by Control-Alt-F1 and kill
- the screensaver (or just set a password for the knoppix user).
-
- If you would like to edit your X-Server configuration manually
- (/etc/X11/XF86Config-4 for XFree86 V4.x), use "knoppix 2" to boot
- into runlevel 2 (textmode only) and, after changing the X
- configuration, start the X environment with "init 5". Note that
- you can always leave the graphical environment with "init 2", and
- restart it later with "init 5".
