Now that you've completed the inventory of your system, it's time to put the list to

good use. The first thing you should do is compare the hardware in your inventory with a

list of hardware that Linux supports. Table 1.1 contains a short list of supported items. A

more comprehensive list is available on the Web at the

following site:

Virtually all IDE, EIDE, and SCSI hard drives

EIDE standard.

Most of the common controllers from manufacturers

such as BusLogic and Adaptec are supported.

Video Card

Many cards from ATI, Cirrus, and Matrox are

supported, as are most cards built around the S3 chipset.

<P>If some of your hardware isn't supported, then you have the following alternatives:

</P>



<UL>

<LI>          Change out the hardware with items that are supported.

<LI>          Check back later to see if support for the hardware is available.

</UL>



<P>It's a good idea to avoid any hardware that's labeled as Plug and Play ready. While

Linux is starting to support plug-and-play hardware, it's currently not always a simple task to

set up. It also would be prudent to avoid any hardware that's listed as a Win-item (like

a Winmodem or a Winprinter). These items currently only work with a Microsoft

Windows operating system.

Creating the Installation Floppies

</A></H3>



<P>The next step is to create the boot and supplemental floppies. You need the two

blank, formatted floppies discussed earlier in the hour. Label the blank floppies &quot;Boot

Diskette&quot; and &quot;Supplemental Diskette.&quot; These diskettes are created by using the

rawrite program located on the CD. The rawrite

program works by writing a disk image to a blank floppy.

</P>



<P>The following example assumes that your CD is drive E: on your system. Please

substitute your drive letter if it's different. At the DOS prompt, change into the

\DOSUTILS directory on the CD and run the rawrite program. You will be prompted by the following:

</P>



<!-- CODE SNIP //-->

<PRE>

Enter disk image source file name: E:\images\boot.img

Enter target diskette drive: A:

Please insert a formatted diskette into drive A: and press --ENTER-- :

</PRE>

<!-- END CODE SNIP //-->



<P>After the image is written, remove that floppy and insert the floppy you

labeled &quot;Supplemental Diskette,&quot; then rerun the

rawrite program.

</P>



<!-- CODE SNIP //-->

<PRE>

Enter disk image source file name: E:\images\supp.img

Enter target diskette drive: A:

Please insert a formatted diskette into drive A: and press --ENTER-- :

</PRE>

<!-- END CODE SNIP //-->



<P>Your installation diskettes are now ready; the next step is to prepare your hard drive.

</P>



<H3><A NAME="ch01_ 9">

Preparing Your Hard Drive

</A></H3>



<P>Since you are installing Linux to a hard drive in your system, you need to make sure

you have necessary room to perform the installation. If you already have a second hard

drive or a partition set aside for Linux, you're pretty much ready to begin the installation. If

you don't, you have to make space available on your existing hard drive by using a program

that comes with the CD called fips. Before you do that, however, you need to have a

basic understanding of partitions and file systems.

</P>



<H4><A NAME="ch01_ 10">

Partitions and File Systems

</A></H4>



<P>As discussed earlier, Linux should be installed into its own partition. All hard drives

need to be partitioned before they can be used. When you partition a drive, you're

designating a specific area of your hard drive for use. Partitions allow you to divide your hard

drive so that not all information is stored in one area. Different operating systems

write information to partitions in different ways, and these different ways are known as

file systems.

</P>





<A NAME="PAGENUM-8"><P>Page 8</P></A>





<B>

Partitions

</B>



<P>There are two types of partitions: primary and extended. Extended partitions can

be subdivided into more parts through the use of logical drives; primary partitions

cannot. A hard drive can contain both types of partitions at the same time, with some

limitations. A drive can contain up to four primary partitions. To divide a hard drive up even

further, one of these partitions may be designated as an extended partition. Each extended

partition can be divided up using logical drives.

</P>



<P>Figure 1.1 shows you an example of a drive that has been broken down into four

distinct areas using one primary partition and one extended partition that has been further

divided into three logical drives.

</P>

</P>



<B>

File Systems

</B>



<P>Whereas the partition tells the operating system &quot;Write information in this area,&quot; a

file system tells the operating system &quot;Write the files in this format!&quot; DOS versions

5.0_7.0 use a file system called FAT16 that allows for 512 megabyte partitions (and larger

ones through some fancy footwork that are beyond the discussion of this book). Windows

95 OSR2 can use a FAT32 file system, which allows for much larger partitions.

Linux primarily uses two file systems called EXT2 and SWAP.

</P>

<BLOCKQUOTE>

If you're using Windows NT, OS/2, or have Windows 95 OSR2 with a

FAT32 partition, you may have problems using the

fips commands. You need to look to a commercial partition program (such as Partition Magic) to create the

necessary space.
