=== General Installation Information ===
==== Sudoing ====
First of all for security reason all accounts are blocked - ie you can't log in to any account. To run things as a root the user 'knoppix' is allowed to sudo - ie to run things as a root.
==== Script ====
Christian Perle provided us a script to copy and define knoppix to a "prepared partition" in your disk. But first we have to set an empty partition on our disk. (With the new script, knoppix-installer, by Fabian Franz this changed a bit.)
==== Preparing a New Partition ====
Before partitioning the disk backup any data you don't want erased! To partition your drive use "parted /dev/DESIRED_DISK(hda,hdb...)". The ? key to get a list of commands for resizing partitions and making a new ext3 partition.
==== Activating the script ====
From Knoppix 3.3 and onward open a terminal and enter:
*'''sudo knoppix-installer
For Knoppix before 3.3 enter:
*'''sudo knx-hdinstall
Simply follow the instructions on screen.

You also might want to check: http://debian.tu-bs.de/knoppix/installer/
for a newer version or use the script '''knoppix-installer-latest-web'''

=== Questions ===
==== Q: Why does "df" not list my root partition ("/")? ====
A: The entry for "/" is somehow missing in /etc/mtab. Either edit that file and add a correct line for "/" or better replace /etc/mtab with a link to /proc/mounts, thn everything should be shown.
*'''su -c "ln -sf /proc/mounts /etc/mtab"

==== Q: Why is DMA disabled by default and how do I enable it? ====
A: Some chipsets and/or harddiscs are broken or buggy. Using DMA would cause problems on such systems. If your system works properly with DMA, you can enable it with it by typing "/sbin/hdparm -c3 -d1 -m16 -k1 /dev/hda" or by editing the "/etc/init.d/bootmisc.sh" startup script and uncommenting the hdparm -qd1 /dev/hda line to have it permanently on at reboot, if the line is not there add it.

A cleaner way to do it requires installing the hdparm package (use the command "apt-get install hdparm" to do this) and edit
the file "/etc/hdparm.conf".

==== Q: How do I test the downloaded ISO file? ====
A: You can use md5sum -c filename.md5 in Linux or [http://www.toast442.org/md5gui.shtml md5gui] for windows.

==== Q: How do I install Knoppix over a Network? ====

A: [[Install Over Net HowTo]]

==== Q: Is there a way that does not use so much space? ====

A: There is the "[[Poor Mans Install]]", where you can copy some files from the CD to the harddisk. It will run like from CD, but the CDROM is free for other use and its a bit faster. Although you'll need a bootfloppy or change the [http://en.wikipedia.org/wiki/Bios Bios] options to boot first the hard disk with Knoppix (i.e. the second hard disk or d: unit).

==== Q: Is there other way that does not use so much space? Perhaps by having a compressed file system? ====

A: Yes, you can install Knoppix in 700 megs instead of 2.3 gigs for the real install, but it will run as if it were from a physical CD, so you cannot install anything, unless you do a 'normal' install. Each time you boot your hardware will need to be redetected. This is not for novices. For more information see the HOWTO for the [[Hd Based HowTo]] hard drive based install.

==== Q: Why doesn't my sound work? ====

A: Just run "/etc/init.d/alsa-autoconfig" as [[root]] once and you'll be fixed up nicely. To have the sound levels set at boot (alsa defaults to muted) edit the file "/etc/init.d/bootmisc.sh" and add '''aumix -w 75 -v 75''' to the bottom of the file.

==== Q: How do I install the latest Gnome? ====

A: Comment all the lines in /etc/apt/sources.list except by the unstable ones.
*'''apt-get update
*'''apt-get install gnome

In order to have gnome-session working you must exec the following and choose metacity
*'''update-alternatives --config x-window-manager

Optionally you can also install gdm, galeon, evolution, etc.

==== Q: how to install knoppix-terminalserver and/or knoppix-terminalopenmosixserver ??? ====
