<title>Finding Sources of Hardware Information</title>
149
In many cases, the installer will be able to automatically detect your
150
hardware. But to be prepared, we do recommend familiarizing
151
yourself with your hardware before the install.
155
Hardware information can be gathered from:
162
The manuals that come with each piece of hardware.
167
The BIOS setup screens of your computer. You can view these screens
168
when you start your computer by pressing a combination of keys. Check
169
your manual for the combination. Often, it is the <keycap>Delete</keycap> key.
174
The cases and boxes for each piece of hardware.
178
<listitem arch="i386"><para>
180
The System window in the Windows Control Panel.
186
System commands or tools in another operating system, including file
187
manager displays. This source is especially useful for information
188
about RAM and hard drive memory.
193
Your system administrator or Internet Service Provider. These
194
sources can tell you the settings you need to set up your
195
networking and e-mail.

<title>Hardware Compatibility</title>
291
Many brand name products work without trouble on Linux. Moreover,
292
hardware for Linux is improving daily. However, Linux still does not
293
run as many different types of hardware as some operating systems.
295
</para><para arch="i386">
297
In particular, Linux usually cannot run hardware that requires a
298
running version of Windows to work.
300
</para><para arch="i386">
302
Although some Windows-specific hardware can be made to run on Linux,
303
doing so usually requires extra effort. In addition, Linux drivers
304
for Windows-specific hardware are usually specific to one Linux
305
kernel. Therefore, they can quickly become obsolete.
307
</para><para arch="i386">
309
So called win-modems are the most common type of this hardware.
310
However, printers and other equipment may also be Windows-specific.
314
You can check hardware compatibility by:
319
Checking manufacturers' web sites for new drivers.
324
Looking at web sites or manuals for information about emulation.
325
Lesser known brands can sometimes use the drivers or settings for
331
Checking hardware compatibility lists for Linux on web sites
332
dedicated to your architecture.
337
Searching the Internet for other users' experiences.

<title>Network Settings</title>
350
If your computer is connected to a network 24 hours a day (i.e., an
351
Ethernet or equivalent connection — not a PPP connection), you
352
should ask your network's system administrator for this information.
357
Your host name (you may be able to decide this on your own).
367
Your computer's IP address.
372
The netmask to use with your network.
377
The IP address of the default gateway system you should route to, if
378
your network <emphasis>has</emphasis> a gateway.
383
The system on your network that you should use as a DNS (Domain Name

</para><para condition="supports-dhcp">
391
On the other hand, if your administrator tells you that a DHCP server
392
is available and is recommended, then you don't need this information
393
because the DHCP server will provide it directly to your computer
394
during the installation process.
398
If you use a wireless network, you should also find out:
403
ESSID of your wireless network.
408
WEP security key (if applicable).
