and mount or unmount hard drives or other devices. According to Red Hat Software,
this command should be used instead of the control-panel's

Editing or changing the characteristics of Linux, DOS, or other partitions
is inherently dangerous, and could cause you to lose data. Always keep a
backup of your /etc/inittab file, which contains a database of the various
filesystems available to Linux.

Probing Your Mouse with the mouseconfig Command
</A></H4>

devices installed on your system. If you have a two-button mouse, you this command enables
you to set your mouse to emulate three buttons.

Installing Sound Service with the sndconfig Command
</A></H4>
<P>The sndconfig command represents a breakthrough in sound configuration for Linux.
Until sndconfig, you generally had to recompile the Linux kernel to add sound or support
for different types of sound cards. The sndconfig command uses loadable modules, found
under the /lib/modules/2.0.31/misc directory to configure your kernel to handle your sound system.
</P>
<P>The sndconfig command presents a dialog box from which you can
select one of five different Sound Blaster or Sound Blaster-compatible sound cards. After you select a card, press
the Enter key; you can then edit the hardware's input/output value, IRQ, or DMA channels.

<BLOCKQUOTE>
Be sure to have your sound card's documentation on hand when you use
the sndconfig command. Don't play guessing games with values for five
different sound cards and 20 different settings. It's best to enter correct values and
not waste time configuring Linux for sound.
</BLOCKQUOTE>
</TD></TR>
</TABLE>
<P>The sndconfig program then tests your configuration by trying to play a sample
sound, called sample.au, located in the
/usr/share/sndconfig directory (if you hear the sample, you'll
hear Linus Torvald's voice, and know how to pronounce the word Linux!). Tell the
sndconfig command that you heard the sound by tabbing to the Yes button and pressing the
Enter

key, and the correct settings for your sound card and the kernel module, sound.o, will
be written into the file conf.modules, found under the
/etc directory.

Setting the System Time with the timeconfig Command

<P>The timeconfig command is used to set the location and timezone of your computer.
This command can be handy if you travel with your computer and need to tell Linux the
current local time.

Configuring X11 with Xconfigurator
</A></H4>
<P>The Xconfigurator command is used to configure the X Window System to run on
your computer's hardware. For details about configuring X11, see Hour 3, "Configuring the
X Window System."
