SliTaz can be used straight from a CD-ROM or USB memory stick, without being installed to a hard drive. There are a number of ways to use the Live media, with options to customise how it starts.

SliTaz runs entirely in memory (RAM), independently of the installed host system. It will not damage your other operating system(s) in any way, so you are perfectly safe to try out SliTaz.

To start using SliTaz from a CD-ROM, just burn the ISO image onto a blank disc and reboot your computer, leaving the disc in your CD-ROM drive. SliTaz will load automatically, detecting your hardware configuration to start.

In most cases, your computer is already configured to boot from the CD-ROM. If the SliTaz splash screen does not appear, you can change the boot order via the BIOS set-up interface. This is different with each computer but can often be done by pressing a key such as the F11, F12, Esc button directly after turning on, before your operating system starts. You can then change the boot sequence and settings so that the CD-ROM comes first. Finally, save your changes before leaving the BIOS configuration interface.

When the SliTaz Live media starts, the splash image will be presented. This is the isolinux boot-loader, which affects options to start SliTaz. You can just press ENTER to use the default settings, or enter options.

When the loading process has finished, you can log-in to the desktop as the tux user, without any password. To use the administrator account, or root, you can start a Terminal and type the command su. The default password is root.

The SliTaz LiveCD accepts various boot options at the prompt. There are two types of options: options handled by SliTaz software and those generally handled by the Linux kernel.

The options for SliTaz are used by various start-up scripts; the parameters such as the VGA mode are managed directly by the Kernel (kernel boot parameters). To pass options at start-up, just precede your commands with slitaz when the splash screen and boot: prompt is displayed. For example,

 slitaz vga=791 no387

On GNU/Linux systems, parameters specific to the Kernel vary greatly depending on the configuration used during the build. The SliTaz-built kernel has few core modules, compensated by loading others on-demand. This means few modifiable parameters are available at start-up. However, you can disable the emulation of a math coprocessor via

• no387
  • Disables the emulation of a math co-processor.

• irqpoll
  • Turn on in case of problems with interrupts, shown by problems with the CD-ROM.

• vga=XXX
  • Specifies the kernel graphics mode. The SliTaz kernel displays the Tux penguin logo and manages the display of the Linux terminal by providing a basic video output mode, called the VGA/VESA frame-buffer. The following table lists the codes used; select a resolution and colour combination:

• home=usb
  • Specifies a /home directory to use within the Live environment. This will include your bookmarks, downloads and desktop customisations. To store your data permanently, you need USB media with a partition formatted in ext3; see the Live USB page for more information. In most cases home=usb can be used for sdb1, or home=devname where the equivilent /dev node can be specified. Note that you can also specify the device using the partition UUID or label by using home=* . Example:

slitaz home=sdb1 

• Prepare USB media

All USB media can formatted in the native Linux ext3 filesystem. Ext3 is a journaled, stable filesystem, it allows you to keep permissions on all files and is much more secure than the default Windows FAT32 filesystem. To format USB media you have a few options: the command line with mkfs.ext3, the tazusb utility or graphically with Gparted. To get a full list of available partitions including the USB drive you can use the command fdisk -l and then format. Example:

 fdisk -l
 tazusb format /dev/sda1

• lang=XX
• kmap=XX
  • Sets the system language & keyboard mapping. Each are codes such as en, de or fr_CH. Alternatively, set your country code and press ENTER to sets the locale and refreshes the boot-loader; other options can then be entered as normal. To skip the language and keyboard configuration you can simply type options on the command line, for English/UK:

 slitaz lang=en kmap=en 

• config=<device>,<path>
  • Executes a script at SliTaz boot time. The script can be located on external media or a HD partition, specified with the device & path variables. For example, the script can mount an ISO image on /usr to save memory and boot the LiveCD on computers with only 32 Mb of RAM. An example with a script named slitaz.sh located on the first disk and partition:

slitaz config=/dev/hda1,slitaz.sh 

• screen=<height>x<width>x<colours>
  • Specifies the desktop screen resolution. These follow the standard pattern, e.g. 1024x768x24

 slitaz screen=1024x768x24 

• sound=no
  • Disables sound completely. This loads no sound-related kernel modules.

slitaz sound=no 

• sound=noconf
  • Skips automatic configuration of your sound card; you must configure it manually later.

• modprobe=modules
  • Loads specific kernel modules. Many can be loaded by separating with commas.

slitaz modprobe=module1,module2 

• laptop
  • Loads ac and battery Kernel modules - useful for laptop computers.

• previous
  • Used by the TazUSB utility to roll-back to a previous filesystem.

 slitaz previous

When the system has finished its initialization, the screen is cleared and the login prompt (Slim) is displayed. You can choose here to login as the regular tux account (without a password) or as the admisitrative root account (with the root password).

The desktop is powered by Openbox. You can start applications from the menu at the lower-left of the screen. Applications are classified by category and are available in English. Menu, theme and wallpaper can all easily be changed to your needs/preferences, and personal settings and data can be stored on various USB media (Flash key, SD card, etc).

The above information applies also to the text-mode log-in prompt. Once logged in, you can use the many text-mode applications available in SliTaz, such as the basic BusyBox operation, the GNU text editor Nano, or the Clex file manager. Just type the name of the application you wish to start. There is a Command Line Reference page to get you started.
