5 .Ss2 Creating boot tapes
7 Fetch the bootable bootfs image from
9 .Dl Pa \&.../NetBSD-\*V/\*M/installation/bootfs/boot.fs
11 and write it on the beginning of the tape.
14 this is done (for MSCP tape, with SCSI tape the name is
18 .Dl # Ic "mt -f /dev/nrmt0 rewind"
19 .Dl # Ic "dd if=boot.fs of=/dev/nrmt0 conv=osync"
20 .Dl # Ic "mt -f /dev/nrmt0 rewoffl"
24 the tape name is different:
26 .Dl # Ic "mt -f /dev/rmt0h rewind"
27 .Dl # Ic "dd if=boot.fs of=/dev/rmt0h conv=osync"
28 .Dl # Ic "mt -f /dev/rmt0h rewoffl"
30 Of course, if you have a tape unit other than unit 0 you have to use
31 the corresponding unit number.
33 If you wish to install the sets from tape then stage you will need to
34 download the *.tgz files from
36 .Dl Pa \&.../NetBSD-\*V/\*M/binary/sets Ns Ar {50,33}
38 (if your disk is less than 200 MB you will probably want to exclude the
39 X sets) and then before the
43 .Dl # Ic "tar -cvf /dev/nrmt0 *.tgz"
45 When you have booted the bootfs and completed the disk partitioning
46 you will be prompted to
49 At this point you will need to press
51 to suspend the install tool, then
54 .Dl # Ic "mt -f /dev/nrmt0 rewind"
55 .Dl # Ic "mt -f /dev/nrmt0 fsf"
56 .Dl # Ic "tar -xvf /dev/nrmt0"
60 .Dq "install from local dir"
64 If your disk is small you will need to be careful about filling it up.
67 If you are using any other OS to create bootable tapes, remember that
70 be 512 for the file to be bootable!
71 Otherwise it just won't work.
73 .Ss2 Creating boot floppies
75 Fetch the bootable bootfs image from
77 .Dl Pa \&.../NetBSD-\*V/\*M/installation/bootfs/boot.fs
82 It is a 1.2MB bootable image that will boot from any
83 floppy of size 1.2MB and bigger.
86 install from RX50 floppies due to the small size.
87 This may change in the future.
89 All floppies except RX50 use a standardized format for storing data
90 so writing the bootfs to the floppy can be done on any PC.
93 the preferred way to do this is using
96 .Ss2 Booting from NFS server
98 All VAXen that can boot over network uses MOP, a
101 To be able to use MOP, a MOP daemon must be present on one of
102 the machines on the local network.
103 The boot principle is:
104 .(bullet -compact -offset indent
105 The VAX broadcast a wish to load an image.
107 A mopd answers and send the boot program to the VAX.
109 The boot program does rarp/bootp requests, mounts the root file system
110 and loads the kernel.
112 The kernel is loaded and starts executing.
115 If your machine has a disk and network connection, it may be
116 convenient for you to install
119 This involves temporarily booting your machine over NFS, just long enough
120 so you can initialize its disk.
121 This method requires that you have access to an NFS server on your network
122 so you can configure it to support diskless boot for your machine.
123 Configuring the NFS server is normally a task for a system administrator,
128 system as the boot-server, have a look at
131 manual page for guidelines on how to proceed with this.
132 If the server runs another operating system, consult the
133 documentation that came with it.
139 There is also very useful documentation at
140 .Lk http://www.NetBSD.org/docs/network/netboot/
142 You also must install a MOP loader.
143 If you are booting from another
145 machine, the MOP daemons are included in the distribution,
146 otherwise you may have to install a MOP loader.
147 A loader can be found at
148 .Lk ftp.stacken.kth.se:/pub/OS/NetBSD/mopd
149 Fetch the latest and read the
150 installation instructions.
152 The file that should be loaded is called boot and is located in
154 .Dl Pa \&.../NetBSD-\*V/\*M/installation/netboot/boot
156 The kernel to load is the same kernel as the bootfs uses and can
159 .Dl Pa \&.../NetBSD-\*V/\*M/installation/netboot/netbsd.ram.gz
161 From the install program started in the kernel the rest of the system
163 There is also a very good (if somewhat out of date) FAQ for netbooting
165 .Lk http://world.std.com/~bdc/projects/vaxen/VAX-netboot-HOWTO.html
166 that describes netbooting of VAXen from many different OS'es.
