<LI>Your system must be either an ISA, EISA, PCI, or local bus architecture machine. These terms specify how the CPU communicates with hardware, and are a characteristic of your motherboard. Most existing systems use the ISA bus architecture.

<LI>At least 4MB of RAM.

<BR>

<BR>

<LI>  Memory is speed, so if you have more RAM you'll thank yourself for it later. If you're a power user, 8MB should be more than enough for most applications. If you want to run X Window, your system will require at least 8MB of RAM.

<BR>

<BR>

<LI>A hard drive with space available for installing Linux. The amount of space required depends on the amount of software you're installing and how much free space you wish to leave yourself. You can install Linux in very small amounts of disk space, but 
a realistic minimum is about 150MB. For a full system with X and development tools, much more is required. The complete installation can use up 250MB, with more useful for data files.

<BR>

<BR>

<LI>A Hercules, CGA, EGA, VGA, or Super VGA video card and monitor. In general, if your video card and monitor work under MS-DOS or Microsoft Windows, then Linux should be able to use them without any problem. However, if you're going to use the X Window 
system (either Metro-X or Xfree86), some video configurations are not supported.

<P>Linux will also run on a number of laptop machines (some laptops use certain software interrupts to power the memory, and Linux doesn't work well with these systems to date). The best way to find out if Linux will run on your hardware is just to try it 
out.

<P>There are other hardware drivers currently under development for Linux. To use these drivers, however, you usually have to patch them into your kernel code, which assumes that you already have a running Linux system (a kind of chicken-and-egg problem if 
you have not already installed Linux). In such cases, you can install whatever Linux you happen to have and then apply the patches with the Linux patch command.

<BR>

<P>Then there is the issue of tape drives for Linux. There is a working QIC-02 device driver for Linux, supporting Everex/Wangtek cards. There are additional patches for the QIC-02 to support Archive SC402/499R. You can find them in /pub/linux/alpha/qic-02 
directory at tsx-11.mit.edu server. (There have been reports of some bugs in the driver, but you can back up and restore.)

<BR>

<P>Most of the newer tape drivers are all for SCSI drives, so if you have a SCSI tape drive, chances are that it is supported.

<P>Your 4MB of RAM will make X run very slowly. You should have at least 8MB of RAM for running programs in X. You will need another 6MB to 10MB of disk space for the GCC compiler in addition to X if you want to develop applications for X.

<P>As far as mice go, Linux supports both serial and Bus varieties. For the serial mice, you can use Logitech, Microsoft, MouseSystems, or compatibles. The following Bus mice are known to work: Logitech, Microsoft, ATI_XL, and PS/2 (aux).

<P>There you have it, a brief introduction to an operating system that could very well change the way you program. Now for getting yourself ready for Linux.

<P>Assuming that you have hardware compatible with Linux, obtaining and installing the system is not difficult. But be prepared to be a bit frustrated at first, if you are new to UNIX or Linux. The two best defenses against frustration with using Linux are 
the following:

<LI>Get organized.

<LI>Educate yourself about Linux and UNIX.

<BR>

<P>In this chapter we learned about Linux and some of its more prominent features:

<BR>

<UL>

<LI>UNIX is a trademark of X/Open. Linux is not a trademark, and has no connection to the trademark UNIX or X/Open.

<BR>

<BR>

<LI>Linux is designed to run on Intel 80386 and faster CPUs and their compatibles.

<BR>

<BR>

<LI>Linux has most of the UNIX-like features and applications built in to it. These features include a Virtual File System (VFS), networking, multitasking and multiuser capabilities along with a host of applications such as Xfree86, Metro-X, TeX, and the 
GNU utilities.

<BR>

<BR>

<LI>You will learn a lot about operating systems when working with Linux.

<BR>

<BR>

<LI>Linux is copyrighted under the GNU copyleft agreement. See <A HREF="rhlxe.htm" tppabs="http://202.113.16.101/%7eeb%7e/Red%20Hat%20Linux%20Unleashed/rhlxe.htm">Appendix E</A> for the complete text.

<BR>

<BR>

<LI>The hardware requirements for Linux include at least an 80386 processor, a minimum of 100MB of disk space, 4MB of RAM and a 3.5-inch floppy drive.

<BR>

<BR>

<LI>The more memory you have, the faster Linux will run.

<BR>

<BR>

<LI>The swap space on Linux is an area on the disk used by Linux as a scratch area when working with lots of processes.

<BR>

<BR>

<LI>You will need 8MB of RAM to get X Window to run with an acceptable degree of performance.

<BR>

<BR>

<LI>You will need to educate yourself a little on Linux and UNIX before you start the installation procedure. This is especially important if you are new to UNIX.

<BR>

<BR>

<LI>There are several ways of finding help on topics in Linux: The Linux Documentation Project, via FAQs, INFO-SHEETS, and from the files on the CD-ROM itself.

<BR>

<BR>

<LI>The Hardware-HOWTO document contains a lot of information about all the devices supported by Linux.

<BR>

<BR>

</UL>

<P>It's best to check the Linux Hardware Compatibility List on the CD-ROM before starting your installation process or buying anything for your PC.
