10 CD #1 of official Debian CD-ROM sets for &arch-title; will present a
11 <prompt>boot:</prompt> prompt on most hardware. Press
12 <keycap>F3</keycap> to see the list of kernel options available
13 from which to boot. Just type your chosen flavor name (idepci,
14 vanilla, compact, bf24) at the <prompt>boot:</prompt> prompt
15 followed by &enterkey;.

19 If your hardware doesn't support booting of multiple images, put one
20 of the other CDs in the drive. It appears that most SCSI CD-ROM drives
21 do not support <command>isolinux</command> multiple image booting, so users
22 with SCSI CD-ROMs should try either CD2 (vanilla) or CD3 (compact),
23 or CD5 (bf2.4).
24
25 </para><para>
26
27 CD's 2 through 5 will each boot a
28 different ``flavor'' depending on which CD-ROM is
29 inserted. See <xref linkend="kernel-choice"/> for a discussion of the
30 different flavors. Here's how the flavors are laid out on the
31 different CD-ROMs:

85 this, you have to press <keycap>F8</keycap> at exactly the right
86 moment (and optionally select the `safe mode command prompt only'
87 option). Enter the subdirectory for the flavor you chose, e.g.,
88
89 <informalexample><screen>
90
91 cd c:\install
92

100 Please note, there is currently a loadlin problem (#142421) which
101 precludes <filename>install.bat</filename> from being used with the
102 bf2.4 flavor. The symptom of the problem is an
103 <computeroutput>invalid compressed format</computeroutput> error.

111 <title>Booting from linux using <command>LILO</command> or
112 <command>GRUB</command></title>
113
114 <para>
115 To boot the installer from hard disk, you must first download
116 and place the needed files as described in <xref linkend="boot-drive-files"/>.
117 </para>
118
119 <para>
120 If you intend to use the hard drive only for booting and then
121 download everything over the network, you should download the
122 netboot/initrd.gz file and its corresponding kernel. This will allow you
123 to repartition the hard disk from which you boot the installer, although
124 you should do so with care.
125 </para>
126
127 <para>
128 Alternatively, if you intend to keep an existing partition on the hard
129 drive unchanged during the install, you can download the hd-media/initrd.gz
130 file and its kernel, as well as copy a CD iso to the drive (make sure the
131 file is named ending in ".iso". The installer can then boot from the drive
132 and install from the CD image, without needing the network.
133 </para>
134
135 <para>
136 For <command>LILO</command>, you will need to configure two
137 essential things in <filename>/etc/lilo.conf</filename>:
138 <itemizedlist>
139 <listitem><para>
140
141 to load the <filename>initrd.gz</filename> installer at boot time;
142
143 </para></listitem>
144 <listitem><para>
145
146 have the <filename>vmlinuz</filename> kernel use a RAM disk as
147 its root partition.
148
149 </para></listitem>
150 </itemizedlist>
151
152 Here is a <filename>/etc/lilo.conf</filename> example:
153
154 </para><para>
155
156 <informalexample><screen>
157
158 image=/boot/newinstall/vmlinuz

161 root=/dev/ram
162 append="devfs=mount,dall"
163
164 </screen></informalexample>
165
166 For more details, refer to the
167 <citerefentry><refentrytitle>initrd</refentrytitle>
168 <manvolnum>4</manvolnum></citerefentry> and
169 <citerefentry><refentrytitle>lilo.conf</refentrytitle>
170 <manvolnum>5</manvolnum></citerefentry> man pages. Now run
171 <userinput>lilo</userinput> and reboot.
172
173 </para><para>
174
175 The procedure for <command>GRUB</command> is quite similar. Locate your
176 <filename>menu.lst</filename> in the <filename>/boot/grub/</filename>
177 directory (sometimes in the <filename>/boot/boot/grub/</filename>),
178 add the following lines:
179
180 <informalexample><screen>
181
182 title New Install
183 kernel (hd0,0)/boot/newinstall/vmlinuz root=/dev/ram devfs=mount,dall
184 initrd (hd0,0)/boot/newinstall/initrd.gz
185
186 </screen></informalexample>
187
188 and reboot. Please note that you may need an additional parameter
189 <userinput>ramdisk_size=<replaceable>size in KB</replaceable></userinput>,
190 depending on the image you are booting. From now on, there should be
191 no difference between <command>GRUB</command> or <command>LILO</command>.

198 <para>
199
200 Lets assume you have prepared everything from <xref
201 linkend="boot-dev-select"/> and <xref linkend="boot-usb-files"/>. Now
202 just plug your USB stick into some free USB connector and reboot the
203 computer. The system should boot up, and you should be presented with
204 the <prompt>boot:</prompt> prompt. Here you can enter optional boot
205 arguments, or just hit &enterkey;.
206
207 </para><para>
208
209 In case your computer doesn't support booting from USB memory devices,
210 you can still use a single floppy to do the initial boot and then
211 switch to USB. Advance according to <xref linkend="floppy-boot"/>; the
212 kernel on boot floppy should detect your USB stick automatically. When
213 it asks for the root floppy, simply press &enterkey;. You should see
214 &d-i; starting.
215
216 </para>

218
219 <sect2 arch="i386" id="floppy-boot">
220 <title>Booting from Floppies</title>
221 <para>
222
223 You will have already downloaded the floppy images you needed and
224 created floppies from the images in <xref linkend="create-floppy"/>.
225 <!-- missing-doc FIXME If you need to, you can also modify the boot floppy; see
226 <xref linkend="rescue-replace-kernel"/>. -->
227
228 </para><para>
229
230 To boot from the installer boot floppy, place it in the primary floppy
231 drive, shut down the system as you normally would, then turn it back
232 on.
233
234 </para><para>
235
236 For installing from a LS-120 drive (ATAPI version) with a set of
237 floppies, you need to specify the virtual location for the floppy
238 device. This is done with the <emphasis>root=</emphasis> boot
239 argument, giving the device that the ide-floppy driver maps the device
240 to. For example, if your LS-120 drive is connected as the first IDE
241 device (master) on the second cable, you enter
242 <userinput>linux root=/dev/hdc</userinput> at the boot prompt.
243 Installation from LS-120 is only supported by 2.4 and later kernels.
244
245 </para><para>
246
247 Note that on some machines, <keycombo><keycap>Control</keycap>
248 <keycap>Alt</keycap> <keycap>Delete</keycap></keycombo> does not
249 properly reset the machine, so a ``hard'' reboot is recommended. If
250 you are installing from an existing operating system (e.g., from a DOS
251 box) you don't have a choice. Otherwise, please do a hard reboot when
252 booting.
253
254 </para><para>
255
256 The floppy disk will be accessed, and you should then see a screen
257 that introduces the boot floppy and ends with the <prompt>boot:</prompt>
258 prompt.
259
260 </para><para>
261
262 Once you press &enterkey;, you should see the message
263 <computeroutput>Loading...</computeroutput>, followed by
264 <computeroutput>Uncompressing Linux...</computeroutput>, and
265 then a screenful or so of information about the hardware in your
266 system. More information on this phase of the boot process can be
267 found below in <xref linkend="kernel-msgs"/>.
268
269 </para><para>
270
271 After booting from the boot floppy, the root floppy is
272 requested. Insert the root floppy and press &enterkey;, and the
273 contents are loaded into memory. The installer program
274 <command>debian-installer</command> is automatically launched.

328 When the installer boots, you will be presented with the boot prompt,
329 <prompt>boot:</prompt>. You can do two things at the <prompt>boot:</prompt>
330 prompt. You can press the function keys <keycap>F1</keycap> through
331 <keycap>F10</keycap> to view a few pages of helpful information, or
332 you can press <keycap>Enter</keycap> to boot the system.
333
334 </para><para>
335
336 Information on boot parameters which might be useful can be found by
337 pressing <keycap>F3</keycap> through <keycap>F7</keycap>. If you add any
338 parameters to
339 the boot command line, be sure to type the boot method (the default is
340 <userinput>linux</userinput>) and a space before the first parameter (e.g.,
341 <userinput>linux floppy=thinkpad</userinput>). If you simply press &enterkey;,
342 that's the same as typing <userinput>linux</userinput> without any special
343 parameters.
344
345 </para><para>
346
347 Some systems have floppies with ``inverted DCLs''. If you receive
348 errors reading from the floppy, even when you know the floppy is good,
349 try the parameter <userinput>floppy=thinkpad</userinput>.
350
351 </para><para>
352
353 On some systems, such as the IBM PS/1 or ValuePoint (which have ST-506
354 disk drivers), the IDE drive may not be properly recognized. Again,
355 try it first without the parameters and see if the IDE drive is
356 recognized properly. If not, determine your drive geometry
357 (cylinders, heads, and sectors), and use the parameter
358 <userinput>hd=<replaceable>cylinders</replaceable>,<replaceable>heads</replaceable>,<replaceable>sectors</replaceable></userinput>.
359
360 </para><para>
361
362 If you have a very old machine, and the kernel hangs after saying
363 <computeroutput>Checking 'hlt' instruction...</computeroutput>, then
364 you should try the <userinput>no-hlt</userinput> boot argument, which
365 disables this test.
366
367 </para><para>
368
369 If your screen begins to show a weird picture while the kernel boots,
370 eg. pure white, pure black or colored pixel garbage, your system may
371 contain a problematic video card which does not switch to the
372 framebuffer mode properly. Then you can use the boot parameter
373 <userinput>debian-installer/framebuffer=false</userinput> or
374 <userinput>video=vga16:off</userinput> to disable the framebuffer
375 console. Only the english
376 language will be available during the installation due to limited
377 console features. See <xref linkend="boot-parms"/> for details.

386 <para>
387
388 Some laptop models produced by Dell are known to crash when PCMCIA device
389 detection tries to access some hardware addresses. Other laptops may display
390 similar problems. If you experience such a problem and you don't need PCMCIA
391 support during the installation, you can disable PCMCIA using the
392 <userinput>hw-detect/start_pcmcia=false</userinput> boot parameter. You can
393 then configure PCMCIA after the installation is completed and exclude the
394 resource range causing the problems.
395
396 </para><para>
397
398 Alternatively, you can boot the installer in expert mode. You will
399 then be asked to enter the resource range options your hardware
400 needs. For example, if you have one of the Dell laptops mentioned
401 above, you should enter <userinput>exclude port
402 0x800-0x8ff</userinput> here. There is also a list of some common
403 resource range options in the <ulink
404 url="http://pcmcia-cs.sourceforge.net/ftp/doc/PCMCIA-HOWTO-2.html#ss2.5">System
405 resource settings section of the PCMCIA HOWTO</ulink>. Note that you
406 have to omit the commas, if any, when you enter this value in the
407 installer.

415
416 The kernel normally tries to install USB modules and the USB keyboard driver
417 in order to support some non-standard USB keyboards. However, there are some
418 broken USB systems where the driver hangs on loading. A possible workaround
419 may be disabling the USB controller in your mainboard BIOS setup. Another option
420 is passing the <userinput>debian-installer/probe/usb=false</userinput> parameter
421 at the boot prompt, which will prevent the modules from being loaded.
