No one really expects your system to remain stagnant. As your company grows, your computer should be
able to grow with it. You can add more memory or a new printer with little or no changes to the
itself. However, if you need to add something like a hard disk or CD-ROM
drive, you may need to tell the operating system about these changes, especially if the piece you are
adding is the first of its kind.
You tell Linux that you have new hardware by linking in the appropriate drivers in the kernel.
This is done when you run the make conf when you are asked a series of questions about your
hardware. In newer distributions, you will find in your kernel source directory a subdirectory,
Documentation, that contains some very detailed information about what to look out for.
As when you add any device to your system, I need to remind you to have everything planned out
before you start. Know what hardware exists on your machine and what settings each card has. Look at
the documentation to see what settings are possible in case you need to change them. If you are adding
a new device of a particular type, the odds are that you are going to need to make some changes.
