2. FOSS
FOSS stands for Free and Open Source software.
Satisfy 4 degrees of freedom as stated by FSF-
• Freedom to run the program for any purpose
• Freedom to study how the program works, change it to
make it to do what you wish.
• Freedom to redistribute copies to help others.
• Freedom to distribute copies of your modified versions
to others.
http://www.gnu.org/philosophy/free-sw.html
3. Why use FOSS?
• The availability of the source code.
• The right of code modification,
improvement and redistribution.
• Large base of developers and users.
• Have an alternative.
• Free marketing and support.
4. Why FOSS is not yet popular?
• General lack of awareness about the Free
Software and its existence.
• Hardware vendors usually bundle
Windows with their systems and do not
offer choice to the customer!
• False thinking of less user friendliness in
FOSS.
5. Benefits of Using FOSS
• Reducing total cost of Ownership.
• Security
• Reliability/Stability
• Piracy, IPR

9. Installation
First things First
Know about your PC/Laptop/Notebook-
• Processor type and model(Intel family/AMD)
• Processor speed(normally in Ghz)
• RAM size(Physical Memory)
• Hard disk drive size
• Graphics Memory
10. BIOS settings to Boot from media
• Go to BIOS by pressing del key before
boot.
• Go to Advanced BIOS features.
• Select your first boot device.
• If you prefer to boot from CD/DVD media,
select it as your first boot device followed
by HDD or Removable disk.
• Save and reboot by pressing F10
P.S : This setting vary from machine to machine depending upon your vendor.
21. This is important part of installation!
Here you need to select Create custom layout if your installing alongside Windows
This screen shows up in
fedora 13.
22. Make sure you’ve selected proper method
before clicking “Write changes to disk”.
You may lose your data if you select improper method here..!!
27. Okay, this is it.! Now you’re done with all the
housekeeping.!!
Sit back. Have a cup of Coffee/tea/whatever
you want and relax.
Comeback after sometime to see the
following screen..
28. Click “Reboot” and eject your installation
media.
Don’t forget to eject installation media before system reboots…
37. Using RPM
• Know about your kernel and architecture
type. (Use “uname – a” command)
• Download the required rpm file from
internet(rpm.pbone.net , rpmfind.net)
• Install using command-
$su – c “rpm –ivh filename.rpm”
• Press Enter and give your root password and
wait until the prompt returns.
• Sometimes this may result in dependency
problems if they’re not resolved.
39. Using YUM
• More easier way to install any
software/package.
• No need to worry about type of kernel and
architecture.
• But you need internet connection during
installation.
• Command is-
# yum install pkgname
41. Installing VLC player in Fedora
Use the following commands-
$ su –
# rpm –ivh
http://download1.rpmfusion.org/free/fedora/rp
mfusion-free-release-stable.noarch.rpm
# yum install vlc
43. Virtualization
You can use virtualization software to install an
Operating system inside an existing Operating
System!
Limitations: Some devices are not detected and
there must be minimum of 2Gb RAM.
Available virtualization software are-
• Virtual Box
• VMware Player
44. Virtual Box
Installing Virtual Box is as simple as installing any simple
software.
But while installing Operating system inside Virtual box, be
sure to save your virtual drive outside host machine drive.
You can install as many Operating systems as you wish
unless you run out of memory.!
Only .iso image of the OS is enough to install it and no need
of external cd/dvd while installing in virtual box.
58. File system check error
Give root password for maintenance (or type
Ctrl D to Reboot)
59. Enter root password to get the prompt
#
Now simply type “fsck” and press Enter
# fsck
Press y when it asks-
fix errors<y>?
Type “reboot” when the prompt returns
# reboot
Now fedora boots normally if the errors are fixed by
fsck.
60. Rescue the lost Fedora
• This works only if the partition of Fedora is
not formatted or deleted while installing
Windows.
• Need original type of fedora media to
rescue.
• Boot your media to get the following
screen and select “Rescue installed
system”.
63. • Start the Grub shell with the grub command:
# grub
• This will show the grub shell like this-
grub>
• Use the find command to locate the partition
containing the boot files by searching
for /boot/grub/grub.conf . Grub will report
the partition using its own syntax:
grub> find /grub/grub.conf
(hd0,0)
64. • Use the root command to configure the
partition from which the boot files are to be
loaded (use the partition ID from last step):
grub> root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
• Use the setup command with this drive ID to
install the Grub bootloader code:
grub> setup (hd0)
• Quit the Grub shell with quit:
grub> quit
#
65. • Type reboot to get back your Fedora-
# reboot
• Now fedora boots along side with
Windows like it was before.
