+Installing NetBSD is a relatively complex process, but if you have
+this document in hand and are careful to read and remember the
+information which is presented to you by the install program, it
+shouldn't be too much trouble.
+
+Before you begin, you should know the geometry of your hard disk, i.e.
+the sector size (note that sector sizes other than 512 bytes are not
+currently supported), the number of sectors per track, the number of
+tracks per cylinder (also known as the number of heads), and the
+number of cylinders on the disk. The NetBSD kernel will try to
+discover these parameters on its own, and if it can it will print them
+at boot time. If possible, you should use the parameters it prints.
+(You might not be able to because you're sharing your disk with
+another operating system, or because your disk is old enough that the
+kernel can't figure out its geometry.)
+
+If NetBSD will be sharing the disk with DOS or another operating
+system, you should have already completed the section of these notes
+that instructed you on how to prepare your hard disk. You should know
+the size of the NetBSD area of the disk and its offset from the
+beginning of the disk. You will need this information when setting up
+your NetBSD partitions.
+
+You should now be ready to install NetBSD. It might be handy for you
+to have a pencil, some paper, and a calculator handy.
+
+The following is a walk-through of the steps you will take while
+getting NetBSD installed on your hard disk. If any question has a
+default answer, it will be displayed in brackets ("[]") after the
+question. If you wish to stop the installation, you may hit Control-C
+at any time, but if you do, you'll have to begin the installation
+process again from scratch.
+
+ Boot your machine using of the appropriate kernel-copy floppy.
+ When presented with the boot prompt (the prompt begins with
+ "Boot" and ends with ":-"), hit return. If the boot prompt
+ does not appear in a reasonable amount of time, you either
+ have a bad boot floppy or a hardware problem. Try writing the
+ kernel-copy floppy image to a different disk, and using that.
+ If that doesn't work, try booting after disabling your CPU's
+ internal and external caches (if any). If it still doesn't
+ work, NetBSD probably can't be run on your hardware. This can
+ probably be considered a bug, so you might want to report it.
+ If you do, please include as many details about your system
+ configuration as you can.
+
+ It will take a while to load the kernel from the floppy,
+ probably around a minute or so. After its loaded, you will be
+ presented with the message:
+ "Insert file system floppy"
+ If you do not see that message after a reasonable time has
+ elapsed, or the spinning cursor has stopped and nothing
+ further has happened, either your boot floppy is bad or you
+ are having hardware problems, and should proceed as outlined
+ above.
+
+ Once you have reached that prompt, remove the kernel-copy
+ floppy from the floppy drive. Make sure that the installation
+ disk (the "inst-10" floppy) is writable, insert it into the
+ floppy drive, and hit any key.
+
+ You will then be presented with the NetBSD kernel boot
+ messages. You will want to read them, to determine your
+ disk's name and geometry. Its name will be something like
+ "sd0" or "wd0" and the geometry will be printed on a line that
+ begins with its name. As mentioned above, you will need your
+ disk's geometry when creating NetBSD's partitions. You will
+ also need to know the name, to tell the install tools what
+ disk to install on.
+
+ While booting, you will probably see several warnings. You
+ should be warned that no swap space is present, and that
+ init(8) cannot find /etc/rc. Do not be alarmed, these are
+ completely normal. When you reach the prompt asking you for a
+ shell name, just hit return.
+
+ You will be presented with a welcome message and a prompt,
+ asking if you wish to proceed with the installation process.
+ If you wish to proceed, enter "y" and hit return.
+
+ You will be asked what type of disk driver you have. The
+ valid options are listed by the install program, to make sure
+ you get it right. If you're installing on an ST-506 or ESDI
+ drive, you'll be asked if your disk supports automatic sector
+ forwarding. If you are SURE that it does, reply
+ affirmatively. Otherwise, the install program will
+ automatically reserve space for bad144 tables.
+
+ The install program will then tell you which disks of that
+ type it can install on, and ask you which it should use.
+ Reply with the name of your disk. (The first disk of the type
+ you selected, either "wd0" for ST-506/ESDI/IDE disks, or "sd0"
+ for SCSI disks, is the default.)
+
+ You will then be asked to name your disk's disklabel. The
+ default response is "mywd" or "mysd" depending on the type of
+ your disk, and for most purposes it will be OK. If you choose
+ to name it something different, make sure the name is a single
+ word and contains no special characters. You don't need to
+ remember this name.
+
+ You will be prompted for your disk's geometry information,
+ i.e. the number of bytes per sector, cylinders on the disk,
+ tracks per cylinder (heads), and sectors per track. Enter
+ them when they are requested. If you make a mistake, hit
+ Control-C and when you get to the shell prompt, restart the
+ install process by running the "install" command. Once you
+ have entered this data, the install program will tell you the
+ total size of your disk, in both sectors, and cylinders.
+ Remember this number; if you're installing on the whole disk,
+ you'll need it again soon.
+
+ When describing your partitions, you will have the option of
+ entering data about them in units of disk sectors or
+ cylinders. If you choose to enter the information in units of
+ sectors, remember that, for optimal performance, partitions
+ should begin and end on cylinder boundaries. You will be
+ asked about which units you wish to use, and you should reply
+ with "c" for cylinders, or "s" for sectors.
+
+ You will be asked for the size of the NetBSD portion of the
+ disk. If you're installing on the whole disk, reply with the
+ size of the disk, as printed earlier by the install program.
+ If you're using only part of the disk, reply with the size
+ that you specified in the partition editor. (Don't forget to
+ enter the size in the units you specified in the last step!)
+
+ If you are not installing on the whole disk, you will be asked
+ fro the offset of the NetBSD partition from the beginning of
+ the disk. Reply with the appropriate offset (again, in
+ whichever units you specified), as determined by how you
+ set up your disk using the partition editor.
+
+ You will be asked to enter the size of your NetBSD root
+ partition. It should be at least 13M, but if you are going to
+ be doing development, 14-16M is a more desirable size. This
+ size should be expressed in units of sectors or cylinders,
+ depending on which you said you wanted to use.
+
+ Next, you will be asked for the size of your swap partition.
+ You should probably allocate twice as much swap space as you
+ have real memory. Systems that will be heavily used should
+ have more swap space allocated, and systems that will be
+ lightly used can get by with less. If you want the system to
+ be able to save crash dumps when it panics, you will need at
+ least as much swap space as you have RAM. Again, this number
+ should be expressed in units of sectors or cylinders, as
+ appropriate.
+
+ The install program will then ask you for information about
+ the rest of the partitions you want on your disk. For most
+ purposes, you will want only one more partition, "/usr".
+ (Machines used as servers will probably also want /var as a
+ separate partition. That can be done with these installation
+ tools, but is not covered here.) The install program will
+ tell you how much space there is left to be allocated in the
+ NetBSD area of the disk, and, if you only want one more
+ partition ("/usr"), you should enter it at the prompt when the
+ installer asks you how large the next partition should be.
+ It will then ask you for the name of the mount point for that
+ partition. If you're doing a basic installation, that is
+ "/usr".
+
+ YOU ARE NOW AT THE POINT OF NO RETURN. Nothing has been
+ written to your disk yet, but if you confirm that you want to
+ install NetBSD, your hard drive will be modified, and its
+ contents may be scrambled at the whim of the install program.
+ This is especially likely if you have given the install
+ program incorrect information. If you are sure you want to
+ proceed, enter "yes" at the prompt.
+
+ The install program will now label your disk and make the file
+ systems you specified. The filesystems will be initialized to
+ contain NetBSD bootstrapping binaries and configuration files.
+ It will also create an /etc/fstab for your system, and mount
+ all of the file systems under /mnt. (In other words, your root
+ partition will be mounted on /mnt, your /usr partition on
+ /mnt/usr, and so on.) There should be no errors in this
+ section of the installation. If there are, restart from the
+ beginning of the installation process.
+
+ You will be placed at a shell prompt ("#"). The remaining
+ tasks are to copy the kernel from the kernel copy floppy to
+ the hard drive's root filesystem and install the distribution
+ sets. The flow of installation differs depending on your
+ hardware resources, and on what media the distribution sets
+ reside.
+
+ To install from floppy:
+ If you only have only one floppy drive, the order of
+ installation is different. Follow the directions in
+ the "Kernel installation" section which will help you
+ install a kernel on the hard drive and then boot off
+ the hard drive, then continue with the rest of the
+ process described here to install the distribution
+ sets from floppy:
+
+ The first thing you should do is pick a temporary
+ directory where the distribution files can be stored.
+ To do this, enter the command "Set_tmp_dir", and enter
+ the name of the temporary directory. (Don't forget
+ that if your disk is still mounted under /mnt; you
+ should probably pick a directory under /mnt/usr.)
+
+ After you have picked a temporary directory, enter the
+ "Load_fd" command, to load the distribution sets from
+ your floppies.
+
+ You will be asked which floppy drive to use. Enter
+ "0" (zero) if you're using the first floppy drive
+ (i.e. what DOS would call "A:"), or enter "1" if
+ you're using the second. (Remember that you CANNOT
+ use the floppy drive that you booted from. If you
+ booted from "A:", you must load from "B:".)
+
+ You will be prompted to insert a floppy into the drive,
+ to have its contents copied to your hard disk. Do so,
+ and hit return to begin copying. When that is done,
+ read the remainder of the floppies that contain the
+ distribution sets that you want to install, one by
+ one. When the last is read, and you are being
+ prompted for another, hit Control-C.
+
+ Run the "Extract" command once for each distribution
+ set you wish to install. For instance, if you wish to
+ install the "base10" distribution set, followed by the
+ "man10" distribution set, and finally the "etc10"
+ distribution set, use the commands:
+ Extract base10
+ Extract man10
+ Extract etc10
+
+ For each extraction, it will ask you if the extraction
+ should be verbose. If you reply affirmatively, it
+ will print out the name of each file that's being
+ extracted.
+
+ (Note: if you know that you will be running low on
+ disk space when installing NetBSD, you can load and
+ extract one distribution set at a time. To do this,
+ load only the floppies which contain the files for the
+ first distribution set, extract them, and then change
+ to the temporary directory and remove them with the
+ command "rm set_name.??".)
+
+ Once you are finished extracting all of the sets that
+ you wish to install, you should proceed to the
+ instructions below (after the last install medium
+ type-specific instructions), that explain how you
+ should configure your system.
+
+ To install from tape:
+ The first thing you should do is pick a temporary
+ directory where the distribution files can be stored.
+ To do this, enter the command "Set_tmp_dir", and enter
+ the name of the temporary directory. (Don't forget
+ that your disk is mounted under /mnt; you should
+ probably pick a directory under /mnt/usr.) The
+ default is /mnt/usr/distrib.
+
+ After you have picked a temporary directory, enter the
+ "Load_tape" command, to load the distribution sets from
+ tape.
+
+ You will be asked which tape drive to use. The
+ default is "rst0", which is correct if you're using
+ the SCSI tape drive with the lowest SCSI ID number.
+ (For the SCSI tape drive with the next lowest SCSI ID
+ number, you should use "rst1", and so on.)
+
+ You will be prompted to hit return when you have
+ inserted the tape into the tape drive. When you do,
+ the contents of the tape will be extracted into the
+ temporary directory, and the names of the files being
+ extracted will be printed.
+
+ After the tape has been extracted, to go the directory
+ containing the first distribution set you wish to
+ install. (Depending on how you made the tape, it's
+ probably a subdirectory of the temporary directory you
+ specified above.) Once there, run the "Set_tmp_dir"
+ command again, and accept its default answer by
+ hitting return at the prompt.
+
+ Use the "Extract" command to extract the distribution
+ set. For instance, if you're extracting the "base10"
+ set, use the command:
+ Extract base10
+ You will be asked if you wish the extraction to be
+ verbose. If you reply affirmatively, the name of each
+ file being extracted will be printed.
+
+ Repeat the previous two steps for each distribution
+ set you wish to install. Change to the set's
+ directory, run "Set_tmp_dir", and then run
+ "Extract <set_name>" to extract the set.
+
+ Once you are finished extracting all of the sets that
+ you wish to install, you should proceed to the
+ instructions below (after the last install medium
+ type-specific instructions), that explain how you
+ should configure your system.
+
+ To install via FTP or NFS:
+ The first thing you should do is pick a temporary
+ directory where the distribution files can be stored.
+ To do this, enter the command "Set_tmp_dir", and enter
+ the name of the temporary directory. (Don't forget
+ that your disk is mounted under /mnt; you should
+ probably pick a directory under /mnt/usr.) The
+ default is /mnt/usr/distrib.
+
+ Configure the appropriate ethernet interface (e.g.
+ ed0, ep0, etc.) up, with a command like:
+
+ ifconfig <ifname> <ipaddr> [netmask <netmask>]
+
+ where "<ifname>" is the interface name, like those
+ listed above, and "<ipaddr>" is the numeric IP address
+ of the interface. If the interface has a special
+ netmask, supply the word "netmask" at and that netmask
+ at the end of the command line. (The brackets
+ indicate that those arguments are optional.) For
+ instance, to configure interface ed0 with IP address
+ 129.133.10.10, use the command:
+
+ ifconfig ed0 129.133.10.10
+
+ and to configure interface ep0 with IP address
+ 128.32.240.167 and a special netmask, 0xffffff00, use
+ the command:
+
+ ifconfig ep0 128.32.240.167 netmask 0xffffff00
+
+ If your board selects software selection of the
+ ethernet interface to use, you might have to add
+ special flags to the "ifconfig" command you use.
+ Consult the table below for the appropriate flags:
+
+ Interface Type Connector Flags
+ --------- ---- --------- -----
+ ed with WD/SMC* BNC [none necessary]
+ ed with WD/SMC* UTP [none necessary]
+ ed with WD/SMC* AUI link0
+ ed with 3c503 BNC [none necessary]
+ ed with 3c503 AUI link0
+ ep BNC [none necessary]
+ ep AUI link0
+ ep UTP link0 link1
+
+ * Older WD boards do not support software configuration,
+ and must be configured via jumpers. These flags
+ will have no effect on them.
+
+ In other words, if, in the last example, the AUI port
+ of the board were being used, you would use the
+ command:
+
+ ifconfig ep0 128.32.240.167 netmask 0xffffff00 link0
+
+ If the NFS server or FTP server is not on a directly-
+ connected network, you need to set up a route to it
+ using a command like:
+
+ route add default <gate_ipaddr>
+
+ where <gate_ipaddr> is your gateway's numeric IP
+ address.
+
+ If you are NFS-mounting the distribution sets, mount
+ them on the temporary directory with a command like:
+
+ mount -t nfs <serv_ipaddr>:<dist_dir> <tmp_dir>
+
+ where <serv_ipaddr> is the server's numeric IP address,
+ <dist_dir> is the path to the distribution files on
+ the server, and <tmp_dir> is the name of the local
+ temporary directory.
+
+ Once this is done, proceed as if you had loaded the
+ files from tape, changing to the appropriate
+ directories, running "Set_tmp_dir", and running
+ "Extract" as appropriate.
+
+ If you are retrieving the distribution sets using ftp,
+ change into the temporary directory, and execute the
+ command:
+
+ ftp <serv_ipaddr>
+
+ where <serv_ipaddr> is once again the server's numeric
+ IP address. Get the files with FTP, taking care to
+ use binary mode when transferring the files.
+
+ Once you have all of the files for the distribution
+ sets that you wish to install, you can proceed using
+ the instructions above, as if you had installed from a
+ floppy. (Note that as with the floppy install, if
+ you're short on disk space, you can transfer only one
+ set at a time, extract it, then delete it, to save
+ space.)
+
+ Once you have finished extracting all of the distribution sets
+ that you wish to install, and are back at the "#" prompt, you
+ are ready to configure your system. The configuration utility
+ expects that you have installed the "base10" and "etc10"
+ distribution sets. If you have not, you will not be able to
+ run it successfully (nor will you have a functional system, in
+ any case). To configure your newly-installed NetBSD system,
+ run the command "Configure". It will ask you for the system's
+ host name, domain name, and other network configuration
+ information. It will set up your configuration files and make
+ the device nodes for the newly-installed system.
+
+Kernel Installation:
+
+ Enter "halt" at the prompt to halt the system. When the
+ system is halted, remove the "inst-10" floppy from the floppy
+ drive, and replace it with the NetBSD 1.0 kernel-copy floppy
+ that you previously booted from. Reboot with that floppy.
+ with that floppy.
+
+ Once again, you will be prompted to insert a file system
+ floppy. DO NOT replace the kernel-copy floppy, just hit any
+ key.
+
+ Again, While booting, you may see several warnings. You may
+ be warned that no swap space is present, that init(8) cannot
+ find /etc/rc, and that one or more databases with names like
+ "pwd.db" cannot be found. Do not be alarmed, as, again, these
+ are completely normal. Hit return at the prompt asking you
+ for a shell name.
+
+ You will be presented with a shell prompt, at which you should
+ enter the "copy_kernel" command. It will ask you what
+ partition to copy the kernel to, and you should reply with the
+ name of your root partition (e.g. sd0a or wd0a).
+
+ You will be asked if you are sure that you want to copy the
+ kernel. Reply affirmatively, and it will check the file
+ system on your root partition, mount it, and copy the kernel.
+ Once the kernel is copied, you should use "halt" to halt the
+ system.
+
+ Once the system is halted, remove the kernel-copy floppy from
+ the floppy disk drive, and hit any key to reboot.
+
+Congratulations, you have successfully installed NetBSD 1.0. When you
+reboot into NetBSD, you should log in as "root" at the login prompt.
+There is no initial password, but if you're using the machine in a
+networked environment, you should create yourself an account and
+protect it and the "root" account with good passwords.
+
+Some of the files in the NetBSD 1.0 distribution might need to be
+tailored for your site. In particular, the /etc/sendmail.cf file will
+almost definitely need to be adjusted, and other files in /etc will
+probably need to be modified, as well. If you are unfamiliar with
+UN*X-like system administration, it's recommended that you buy a book
+that discusses it.
