CHEATCODES AND HINTS FOR BitDefender Rescue CD V2.0 ============================================================================== (last update: 02.13.2007) This is an edit of the original KNOPPIX cheatcodes file. Please note that your version might not have all these features. These options (can be combined) work from the ISOLINUX bootprompt: rescue lang=cn|de|da|es|fr|it|nl specify language/keyboard rescue lang=pl|ru|sk|tr|tw|us specify language/keyboard rescue gmt Use GMT-based time rescue tz=Europe/Berlin Use this timezone for TZ rescue atapicd Do NOT use SCSI-Emulation for IDE CD-Roms rescue alsa (or alsa=es1938) Use ALSA sound driver (at your own risk) rescue desktop=fluxbox|icewm Use specified WM instead of KDE (1) rescue desktop=kde|larswm|twm Use specified WM instead of KDE (2) rescue desktop=wmaker|xfce Use specified WM instead of KDE (3) rescue screen=1280x1024 Use specified Screen resolution for X rescue xvrefresh=60 (or vsync=60) Use 60 Hz vertical refresh rate for X rescue xhrefresh=80 (or hsync=80) Use 80 kHz horizontal refresh rate for X rescue xserver=XFree86|XF86_SVGA Use specified X-Server rescue xmodule=ati|fbdev|i810|mga Use specified XFree4-Module (1) rescue xmodule=nv|radeon|savage|s3 Use specified XFree4-Module (2) rescue xmodule=radeon|svga|i810 Use specified XFree4-Module (3) rescue 2 Runlevel 2, Textmode only rescue floppyconfig Run "knoppix.sh" from a floppy rescue myconf=/dev/sda1 Run "knoppix.sh" from a partition rescue myconf=scan (or config=scan) Try to find "knoppix.sh" automatically rescue home=/dev/sda1/rescue.img Mount loopback file as /home/knoppix rescue home=scan Automatic search for knoppix homedir rescue no{apic,agp,apm,audio,ddc} Skip parts of HW-detection (1) rescue no{dhcp,fstab,firewire} Skip parts of HW-detection (2) rescue no{pcmcia,scsi,swap,usb} Skip parts of HW-detection (3) rescue pnpbios=off No PnP Bios initialization rescue acpi=off Disable ACPI Bios completely rescue usb2 Try to initialize USB 2.x controller(s) failsafe Boot with (almost) no HW-detection rescue pci=irqmask=0x0e98 Try this, if PS/2 mouse doesn't work *) rescue pci=bios Workaround for bad PCI controllers rescue ide2=0x180 nopcmcia Boot from PCMCIA-CD-Rom (some notebooks) rescue mem=128M Specify Memory size in MByte rescue dma Enable DMA accelleration for ALL IDE-Drives rescue noeject Do NOT eject CD after halt rescue noprompt Do NOT prompt to remove the CD rescue vga=normal No-framebuffer mode, but X rescue blind Start Braille-Terminal (no X) rescue brltty=type,port,table Parameters for Braille device rescue wheelmouse Enable IMPS/2 protocol for wheelmice rescue nowheelmouse Force plain PS/2 protocol for PS/2-mouse fb1280x1024 Use fixed framebuffer graphics (1) fb1024x768 Use fixed framebuffer graphics (2) fb800x600 Use fixed framebuffer graphics (3) rescue keyboard=us xkeyboard=us Use different keyboard (text/X) rescue splash Boot with fancy background splashscreen + animations + progress bar **) rescue toram Copy CD to RAM and run from there rescue tohd=/dev/hda1 Copy CD to HD partition and run from there rescue fromhd Skip checking for rescue on CD-ROM rescue fromhd=/dev/hda1 Boot from previously copied CD-Image rescue bootfrom=/dev/hda1 Access Image then boot from previously copied CD-Image (enables booting from NTFS / ReiserFS) ***) rescue bootfrom=/dev/hda1/KNX.iso Access image, boot from ISO-Image. ***) rescue knoppix_dir=rescue Directory to search for on the CD. rescue knoppix_name=rescue Cloop-File to search for on the CD. rescue testcd Check CD data integrity and md5sums expert Interactive setup for experts NEW Kernels and Options in version 3.4: rescue26 [Options...] Boots with Kernel 2.6 (2.4 is default) expert26 [Options...] Same for expert mode rescue26 acpi=off Disable ACPI configuration in Kernel 2.6 memtest Run memtest86 instead of Linux *) Try "rescue 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 rescue-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 rescue.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 rescue 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 "rescue 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 rescue-FAQ. In case of a failing hardware autodetection, try booting with any of the "no-" options as shown in the table above, like in rescue 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 "rescue 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 "rescue". 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 "rescue", 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 rescue 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 rescue 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 "rescue 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 graphica...
