- ==============================================================================
- (last update: 16.05.2003)
-
- These options (can be combined) work from the SYSLINUX bootprompt:

- knoppix xmodule=radeon|svga|i810 Use specified XFree4-Module (3)
- knoppix 2 Runlevel 2, Textmode only
- knoppix floppyconfig Run "knoppix.sh" from a floppy
- knoppix myconf=/dev/sda1 Run "knoppix.sh" from a partition
- knoppix myconf=scan Try to find "knoppix.sh" automatically
- knoppix home=/dev/sda1/knoppix.img Mount loopback file as /home/knoppix
- knoppix home=scan Try to find knoppix homedir automatic.
- knoppix no{apic,agp,apm,audio,ddc} Skip parts of HW-detection (1)
- knoppix no{firewire,pcmcia,scsi} Skip parts of HW-detection (2)
- knoppix no{swap,usb} Skip parts of HW-detection (3)
- failsafe Boot with (almost) no HW-detection
- knoppix pci=irqmask=0x0e98 Notebooks, if PS/2 mouse doesn't work
- knoppix pci=bios Workaround for bad PCI controllers
- knoppix ide2=0x180 nopcmcia Boot from PCMCIA-CD (transmeta notebooks)
- knoppix mem=128M Specify Memory size in MByte
- knoppix dma Enable DMA for ALL IDE-Drives
- knoppix noeject Do NOT eject CD after halt
- knoppix-txt No framebuffer at startup
- knoppix vga=normal No-framebuffer mode, but X
- knoppix blind Start Braille-Terminal (no X)
- knoppix brltty=type,port,table Parameters for Braille device
- knoppix wheelmouse Enable IMPS/2 protocol for wheelmice
- knoppix nowheelmouse Force plain PS/2 protocol for PS/2-mouse
- fb1280x1024 Use fixed framebuffer graphics
- fb1024x768 Use fixed framebuffer graphics
- fb800x600 Use fixed framebuffer graphics
- knoppix keyboard=us xkeyboard=us Use different keyboard (text/X)
- knoppix testcd Check CD data integrity and md5sums
- expert Interactive setup for experts
-
- 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).
-
- 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. 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 noddc noapm noapic 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).
-
- 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.)
-
- The "expert" mode provides a very simple and not yet well tested 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 "myconfig=/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.
-
- Starting from Version 2.0, SCSI-Emulation is active for all CD-Roms,
- so IDE CD-Writers should work with the installed versions of cdrecord
- and cdrdao (or the graphical frontends thereof, cdbakeoven, xcdroast
- and gcombust).
-
- If your BIOS does not support el torito booting from CD, you can create
- a bootable floppy disk by issuing (on Linux)
- dd if=mounted_cdrom_directory/KNOPPIX/boot.img of=/dev/fd0 bs=18k
- or, in case of DOS, use the rawrite.exe program provided in the
- KNOPPIX directory on CD.
-
- If you wish to remaster the CD, please don't forget to specify
- -b KNOPPIX/boot.img
- for the german version of the bootfloppy, or
- -b KNOPPIX/boot-en.img
- for the english version, 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 type "ls /usr/X11R6/bin/XF*"
- to see a list of all available X-Servers. Once you verified
- that your X-Server is working correctly, you can run the X startup
- script with "/etc/init.d/xsession start".
