Setting up the Disk Partitions

Here it allows you to organize the storage space on your systemhard disk.

The space on your hard disk is normally divided into sections, calledpartitions, for better management of the space.

Dividing a hard disk into partitions can help you segregate theavailable disk space according to its usage.

The optimum number and size of partitions on your disk depends onoverall disk size, the purpose of each partition, and so on.

Red Hat Linux makes this decision simpler by offering an automatic

partitioning option, which creates an arrangement of partitionsbased on your install type preferences.

So, if you chose the Personal Desktop installation type in previousscreen, your hard disk can be automatically reorganized intopartitions.

If you have existing partitions, and you have asked Red Hat Linux toremove them, you will be asked to confirm to remove the partitions.

Before accepting the removal of the partitions, be aware thatremoval of partitions leads to complete loss of any existing data onthe disk.

The Automatic Installation Process

The Red Hat Linux graphical installation tool has now collected allthe information that it needs to begin the installation. The nextscreen prompts you to begin the software installation.

The software package installation is mostly automatic; the only thing

you need to do is change the CD a couple of times (when promptedto do so).

Before the software is installed, the installation process formats allthe partitions that are supposed to hold these data.

Then, the installation process continues by installing the softwarepackages. Progress bars display the total time taken so far, and the

estimated time of the software installation.

Red Hat Linux normally detect the type of your video card and selectit for you, and it is quite safe to accept the default values.

If you want to be sure that its got the right configuration, check thesetting here against the make, model, and RAM you noted in yourhardware checklist, and adjust as necessary.

Red Hat Linux then proceeds to detect the type of monitor beingused. The monitor detected during installation will be highlighted onthe screen.

The video card and the monitor type allow Red Hat to formulate alist of video modes that can be supported on your computer.

The video mode is determined by the screen resolution and the colordepth (number of colors) in which objects can be shown on screen.

Creating New User Accounts

The root user account this is an administrative (or super user)account that is created by default.

The problem with working as root all the time is that these privilegesmake it very easy to accidentally delete important files that you

dont mean to delete. For this reason, its recommended that you create a normal (non-

administrative) account for your personal use, and use that most ofthe time.

The next screen allows you to do that you just need to choose ausername and password and type your full name too.

When youve done that, click Forward to continue.

Over a period of time, the clock in the computer tends to drift away

from the actual time of the computer.To keep the clock in sync, you can use the Network Time Protocol

(NTP) option in the same screen this allows you to specify an NTPserver, and the machine will keep in sync with it.
