install revision 1.1.2.3 1 Installing NetBSD is a relatively complex process, but if you have
2 this document in hand and are careful to read and remember the
3 information which is presented to you by the install program, it
4 shouldn't be too much trouble.
5
6 Before you begin, you should know the geometry of your hard disk, i.e.
7 the sector size (note that sector sizes other than 512 bytes are not
8 currently supported), the number of sectors per track, the number of
9 tracks per cylinder (also known as the number of heads), and the
10 number of cylinders on the disk. The NetBSD kernel will try to
11 discover these parameters on its own, and if it can it will print them
12 at boot time. If possible, you should use the parameters it prints.
13 (You might not be able to because you're sharing your disk with
14 another operating system, or because your disk is old enough that the
15 kernel can't figure out its geometry.)
16
17 If NetBSD will be sharing the disk with Human68k or another operating
18 system, you should have already completed the section of these notes
19 that instructed you on how to prepare your hard disk. You should know
20 the size of the NetBSD area of the disk and its offset from the
21 beginning of the disk. You will need this information when setting up
22 your NetBSD partitions.
23
24 You should now be ready to install NetBSD. It might be handy for you
25 to have a pencil, some paper, and a calculator handy.
26
27 The following is a walk-through of the steps you will take while
28 getting NetBSD installed on your hard disk. If any question has a
29 default answer, it will be displayed in brackets ("[]") after the
30 question. If you wish to stop the installation, you may hit Control-C
31 at any time, but if you do, you'll have to begin the installation
32 process again from scratch.
33
34 Boot your machine using of the appropriate kernel-copy floppy.
35 If the boot prompt does not appear in a reasonable amount of
36 time, you either have a bad boot floppy or a hardware problem.
37 Try writing the kernel-copy floppy image to a different disk,
38 and using that. If it still doesn't work, NetBSD probably
39 can't be run on your hardware. This can probably be
40 considered a bug, so you might want to report it. If you do,
41 please include as many details about your system configuration
42 as you can.
43
44 It will take a while to load the kernel from the floppy,
45 probably around a minute or so. After its loaded, you will be
46 presented with the message:
47 "Insert file system floppy"
48 If you do not see that message after a reasonable time has
49 elapsed, or the spinning cursor has stopped and nothing
50 further has happened, either your boot floppy is bad or you
51 are having hardware problems, and should proceed as outlined
52 above.
53
54 Once you have reached that prompt, remove the kernel-copy
55 floppy from the floppy drive. Make sure that the installation
56 disk (the "inst121" floppy) is writable, insert it into the
57 floppy drive, and hit any key.
58
59 You will then be presented with the NetBSD kernel boot
60 messages. You will want to read them, to determine your
61 disk's name and geometry. Its name will be something like
62 "sd0" or "wd0" and the geometry will be printed on a line that
63 begins with its name. As mentioned above, you will need your
64 disk's geometry when creating NetBSD's partitions. You will
65 also need to know the name, to tell the install tools what
66 disk to install on.
67
68 While booting, you will probably see several warnings. You
69 should be warned that no swap space is present, and that
70 init(8) cannot find /etc/rc. Do not be alarmed, these are
71 completely normal. When you reach the prompt asking you for a
72 shell name, just hit return.
73
74 You will be presented with a welcome message and a prompt,
75 asking if you wish to proceed with the installation process.
76 If you wish to proceed, enter "y" and hit return.
77
78 You will be asked what type of disk driver you have. The
79 valid options are listed by the install program, to make sure
80 you get it right. If you are SURE that it does, reply
81 affirmatively. Otherwise, the install program will
82 automatically reserve space for bad144 tables.
83
84 The install program will then tell you which disks of that
85 type it can install on, and ask you which it should use.
86 Reply with the name of your disk.
87
88 You will then be asked to name your disk's disklabel. The
89 default response is "mywd" or "mysd" depending on the type of
90 your disk, and for most purposes it will be OK. If you choose
91 to name it something different, make sure the name is a single
92 word and contains no special characters. You don't need to
93 remember this name.
94
95 You will be prompted for your disk's geometry information,
96 i.e. the number of bytes per sector, cylinders on the disk,
97 tracks per cylinder (heads), and sectors per track. Enter
98 them when they are requested. If you make a mistake, hit
99 Control-C and when you get to the shell prompt, restart the
100 install process by running the "install" command. Once you
101 have entered this data, the install program will tell you the
102 total size of your disk, in both sectors, and cylinders.
103 Remember this number; if you're installing on the whole disk,
104 you'll need it again soon.
105
106 When describing your partitions, you will have the option of
107 entering data about them in units of disk sectors or
108 cylinders. If you choose to enter the information in units of
109 sectors, remember that, for optimal performance, partitions
110 should begin and end on cylinder boundaries. You will be
111 asked about which units you wish to use, and you should reply
112 with "c" for cylinders, or "s" for sectors.
113
114 You will be asked for the size of the NetBSD portion of the
115 disk. If you're installing on the whole disk, reply with the
116 size of the disk, as printed earlier by the install program.
117 If you're using only part of the disk, reply with the size
118 that you specified in the partition editor. (Don't forget to
119 enter the size in the units you specified in the last step!)
120
121 If you are not installing on the whole disk, you will be asked
122 fro the offset of the NetBSD partition from the beginning of
123 the disk. Reply with the appropriate offset (again, in
124 whichever units you specified), as determined by how you
125 set up your disk using the partition editor.
126
127 You will be asked to enter the size of your NetBSD root
128 partition. It should be at least 13M, but if you are going to
129 be doing development, 14-16M is a more desirable size. This
130 size should be expressed in units of sectors or cylinders,
131 depending on which you said you wanted to use.
132
133 Next, you will be asked for the size of your swap partition.
134 You should probably allocate twice as much swap space as you
135 have real memory. Systems that will be heavily used should
136 have more swap space allocated, and systems that will be
137 lightly used can get by with less. If you want the system to
138 be able to save crash dumps when it panics, you will need at
139 least as much swap space as you have RAM. Again, this number
140 should be expressed in units of sectors or cylinders, as
141 appropriate.
142
143 The install program will then ask you for information about
144 the rest of the partitions you want on your disk. For most
145 purposes, you will want only one more partition, "/usr".
146 (Machines used as servers will probably also want /var as a
147 separate partition. That can be done with these installation
148 tools, but is not covered here.) The install program will
149 tell you how much space there is left to be allocated in the
150 NetBSD area of the disk, and, if you only want one more
151 partition ("/usr"), you should enter it at the prompt when the
152 installer asks you how large the next partition should be.
153 It will then ask you for the name of the mount point for that
154 partition. If you're doing a basic installation, that is
155 "/usr".
156
157 YOU ARE NOW AT THE POINT OF NO RETURN. Nothing has been
158 written to your disk yet, but if you confirm that you want to
159 install NetBSD, your hard drive will be modified, and its
160 contents may be scrambled at the whim of the install program.
161 This is especially likely if you have given the install
162 program incorrect information. If you are sure you want to
163 proceed, enter "yes" at the prompt.
164
165 The install program will now label your disk and make the file
166 systems you specified. The filesystems will be initialized to
167 contain NetBSD bootstrapping binaries and configuration files.
168 It will also create an /etc/fstab for your system, and mount
169 all of the file systems under /mnt. (In other words, your root
170 partition will be mounted on /mnt, your /usr partition on
171 /mnt/usr, and so on.) There should be no errors in this
172 section of the installation. If there are, restart from the
173 beginning of the installation process.
174
175 You will be placed at a shell prompt ("#"). The remaining
176 tasks are to copy the kernel from the kernel copy floppy to
177 the hard drive's root filesystem and install the distribution
178 sets. The flow of installation differs depending on your
179 hardware resources, and on what media the distribution sets
180 reside.
181
182 To install from floppy:
183 If you only have only one floppy drive, the order of
184 installation is different. Follow the directions in
185 the "Kernel installation" section which will help you
186 install a kernel on the hard drive and then boot off
187 the hard drive, then continue with the rest of the
188 process described here to install the distribution
189 sets from floppy:
190
191 The first thing you should do is pick a temporary
192 directory where the distribution files can be stored.
193 To do this, enter the command "Set_tmp_dir", and enter
194 the name of the temporary directory. (Don't forget
195 that if your disk is still mounted under /mnt; you
196 should probably pick a directory under /mnt/usr.)
197
198 After you have picked a temporary directory, enter the
199 "Load_fd" command, to load the distribution sets from
200 your floppies.
201
202 You will be asked which floppy drive to use. Enter
203 "0" (zero) if you're using the first floppy drive
204 (i.e. what DOS would call "A:"), or enter "1" if
205 you're using the second. (Remember that you CANNOT
206 use the floppy drive that you booted from. If you
207 booted from "A:", you must load from "B:".)
208
209 You will be prompted to insert a floppy into the drive,
210 to have its contents copied to your hard disk. Do so,
211 and hit return to begin copying. When that is done,
212 read the remainder of the floppies that contain the
213 distribution sets that you want to install, one by
214 one. When the last is read, and you are being
215 prompted for another, hit Control-C.
216
217 Run the "Extract" command once for each distribution
218 set you wish to install. For instance, if you wish to
219 install the "base121" distribution set, followed by the
220 "man121" distribution set, and finally the "etc121"
221 distribution set, use the commands:
222 Extract base121
223 Extract man121
224 Extract etc121
225
226 For each extraction, it will ask you if the extraction
227 should be verbose. If you reply affirmatively, it
228 will print out the name of each file that's being
229 extracted.
230
231 (Note: if you know that you will be running low on
232 disk space when installing NetBSD, you can load and
233 extract one distribution set at a time. To do this,
234 load only the floppies which contain the files for the
235 first distribution set, extract them, and then change
236 to the temporary directory and remove them with the
237 command "rm set_name.??".)
238
239 Once you are finished extracting all of the sets that
240 you wish to install, you should proceed to the
241 instructions below (after the last install medium
242 type-specific instructions), that explain how you
243 should configure your system.
244
245 To install from tape:
246 The first thing you should do is pick a temporary
247 directory where the distribution files can be stored.
248 To do this, enter the command "Set_tmp_dir", and enter
249 the name of the temporary directory. (Don't forget
250 that your disk is mounted under /mnt; you should
251 probably pick a directory under /mnt/usr.) The
252 default is /mnt/usr/distrib.
253
254 After you have picked a temporary directory, enter the
255 "Load_tape" command, to load the distribution sets from
256 tape.
257
258 You will be asked which tape drive to use. The
259 default is "rst0", which is correct if you're using
260 the SCSI tape drive with the lowest SCSI ID number.
261 (For the SCSI tape drive with the next lowest SCSI ID
262 number, you should use "rst1", and so on.)
263
264 You will be prompted to hit return when you have
265 inserted the tape into the tape drive. When you do,
266 the contents of the tape will be extracted into the
267 temporary directory, and the names of the files being
268 extracted will be printed.
269
270 After the tape has been extracted, to go the directory
271 containing the first distribution set you wish to
272 install. (Depending on how you made the tape, it's
273 probably a subdirectory of the temporary directory you
274 specified above.) Once there, run the "Set_tmp_dir"
275 command again, and accept its default answer by
276 hitting return at the prompt.
277
278 Use the "Extract" command to extract the distribution
279 set. For instance, if you're extracting the "base121"
280 set, use the command:
281 Extract base121
282 You will be asked if you wish the extraction to be
283 verbose. If you reply affirmatively, the name of each
284 file being extracted will be printed.
285
286 Repeat the previous two steps for each distribution
287 set you wish to install. Change to the set's
288 directory, run "Set_tmp_dir", and then run
289 "Extract <set_name>" to extract the set.
290
291 Once you are finished extracting all of the sets that
292 you wish to install, you should proceed to the
293 instructions below (after the last install medium
294 type-specific instructions), that explain how you
295 should configure your system.
296
297 To install via FTP or NFS:
298 The first thing you should do is pick a temporary
299 directory where the distribution files can be stored.
300 To do this, enter the command "Set_tmp_dir", and enter
301 the name of the temporary directory. (Don't forget
302 that your disk is mounted under /mnt; you should
303 probably pick a directory under /mnt/usr.) The
304 default is /mnt/usr/distrib.
305
306 Configure the SLIP interface, with the following
307 command sequence:
308
309 slattach -h -s <speed> tty00
310 ifconfig sl0 <my_ipaddr> <peer_ipaddr>
311
312 where "<speed>" is the network speed, and "<my_ipaddr>"
313 is the numeric IP address of the machine you are going
314 to install NetBSD/x68k, while "<peer_ipaddr>" is the
315 address of the peer machine connected with your machine.
316 You might have to configure the peer SLIP interface
317 with similar sequence (depending on the peer system).
318
319 For instance, the sequence
320
321 slattach -h -s 38400 tty00
322 ifconfig sl0 192.168.0.1 192.168.0.10
323
324 configures the SLIP interface for the network between
325 your machine (with IP address 192.168.0.1) and the peer
326 (192.168.0.10) with speed 38400 bps. Note that IP
327 addresses 192.168.*.* are the private IP addresses
328 described in RFC 1597.
329
330 If you are NFS-mounting the distribution sets, mount
331 them on the temporary directory with a command like:
332
333 mount -t nfs <serv_ipaddr>:<dist_dir> <tmp_dir>
334
335 where <serv_ipaddr> is the server's numeric IP address,
336 <dist_dir> is the path to the distribution files on
337 the server, and <tmp_dir> is the name of the local
338 temporary directory.
339
340 Once this is done, proceed as if you had loaded the
341 files from tape, changing to the appropriate
342 directories, running "Set_tmp_dir", and running
343 "Extract" as appropriate.
344
345 If you are retrieving the distribution sets using ftp,
346 change into the temporary directory, and execute the
347 command:
348
349 ftp <serv_ipaddr>
350
351 where <serv_ipaddr> is once again the server's numeric
352 IP address. Get the files with FTP, taking care to
353 use binary mode when transferring the files.
354
355 Once you have all of the files for the distribution
356 sets that you wish to install, you can proceed using
357 the instructions above, as if you had installed from a
358 floppy. (Note that as with the floppy install, if
359 you're short on disk space, you can transfer only one
360 set at a time, extract it, then delete it, to save
361 space.)
362
363 Once you have finished extracting all of the distribution sets
364 that you wish to install, and are back at the "#" prompt, you
365 are ready to configure your system. The configuration utility
366 expects that you have installed the "base121" and "etc121"
367 distribution sets. If you have not, you will not be able to
368 run it successfully (nor will you have a functional system, in
369 any case). To configure your newly-installed NetBSD system,
370 run the command "Configure". It will ask you for the system's
371 host name, domain name, and other network configuration
372 information. It will set up your configuration files and make
373 the device nodes for the newly-installed system.
374
375 Kernel Installation:
376
377 Enter "halt" at the prompt to halt the system. When the
378 system is halted, remove the "inst121" floppy from the floppy
379 drive, and replace it with the NetBSD 1.2.1 kernel-copy floppy
380 that you previously booted from. Reboot with that floppy.
381 with that floppy.
382
383 Once again, you will be prompted to insert a file system
384 floppy. DO NOT replace the kernel-copy floppy, just hit any
385 key.
386
387 Again, While booting, you may see several warnings. You may
388 be warned that no swap space is present, that init(8) cannot
389 find /etc/rc, and that one or more databases with names like
390 "pwd.db" cannot be found. Do not be alarmed, as, again, these
391 are completely normal. Hit return at the prompt asking you
392 for a shell name.
393
394 You will be presented with a shell prompt, at which you should
395 enter the "copy_kernel" command. It will ask you what
396 partition to copy the kernel to, and you should reply with the
397 name of your root partition (e.g. sd0a or wd0a).
398
399 You will be asked if you are sure that you want to copy the
400 kernel. Reply affirmatively, and it will check the file
401 system on your root partition, mount it, and copy the kernel.
402 Once the kernel is copied, you should use "halt" to halt the
403 system.
404
405 Once the system is halted, remove the kernel-copy floppy from
406 the floppy disk drive, and hit any key to reboot.
407
408 Congratulations, you have successfully installed NetBSD 1.2.1. When you
409 reboot into NetBSD, you should log in as "root" at the login prompt.
410 There is no initial password, but if you're using the machine in a
411 networked environment, you should create yourself an account and
412 protect it and the "root" account with good passwords.
413
414 Some of the files in the NetBSD 1.2.1 distribution might need to be
415 tailored for your site. In particular, the /etc/sendmail.cf file will
416 almost definitely need to be adjusted, and other files in /etc will
417 probably need to be modified, as well. If you are unfamiliar with
418 UN*X-like system administration, it's recommended that you buy a book
419 that discusses it.
420
