There are two installation tools available. The traditional miniroot
|
|
installer is script-based and may be netbooted or may be dumped to a disk
|
|
and run locally. The ramdisk kernel with the sysinst installation
|
|
utility is more flexible, but can only be netbooted and has not been
|
|
extensively tested.
|
|
.Pp
|
|
There are several possible installation configurations described in this
|
|
document. Other configurations are possible, but less common. If you are
|
|
unable to install based on the information in this document, post a
|
|
message to
|
|
.Mt port-hp300@netbsd.org
|
|
asking for help. The configurations described in this document are as follows:
|
|
.Pp
|
|
.(bullet -compact

\*M netboots
|
|
.Li SYS_UBOOT
|
|
and then runs the miniroot installation tools or a purely diskless
|
|
installation from a
|
|
.Nx
|
|
server on the same subnet (you must have root access).
|
|
Other server platforms will work, but are described in the NetBSD Diskless
|
|
HOW-TO.

|
|
The preferred method is to use another
|
|
.Nx
|
|
server to netboot the \*M client. This procedure will not
|
|
work on the handful of models which are incapable of netbooting.
|
|
In particular, the 320, 350, 330, 318, and
|
|
319 might not have a recent enough BootROM. The BootROM revision is
|
|
printed when your workstation is first powered on (or
|
|
rebooted). Revision B or later will definitely work. BootROMs with
|
|
numeric revisions such as 1.1 (on a 400s) will netboot without any
|
|
problems. You can netboot from any built-in or add-on ethernet board on
|
|
a model with a supported BootROM.

|
.Pp
|

If you have access to a

|
|
drives. SCSI disks can be formatted on any platform with SCSI support and
|
|
then used on
|
|
.Nx*M .
|
|
HP-IB disks can only be formatted by the
|
|
.Tn HP-UX
|
|
.Xr mediainit 1
|
|
command. You may need to first create the device nodes for your disk, as
|
|
.Tn HP-UX
|
|
was never very good about populating
|
|
.Pa /dev/rdsk
|
|
propertly.

.Ss2 Designing your disk's partition table
|
|
.
|
|
This step can sometimes be a real pain, especially when using
|
|
.Pa SYS_INST .
|
|
It's best to calculate it ahead of time.
|
|
.Pp
|
|
If you are installing to an HP-IB disk,
|
|
you will need information about your disk's geometry, based on 512-byte
|
|
sectors. The file
|
|
.Pa installation/misc/HP-IB.geometry
|
|
in the distribution has geometry information for
|
|
several HP-IB disks, but may be incomplete. Geometry may be calculated
|
|
from an HP-UX
|
|
.Pa /etc/disktab
|
|
entry, but note that HP-UX geometry is based
|
|
on 1024 byte sectors, while
|
|
.Nx 's
|
|
is based on 512 byte sectors. You should have all partitions start on
|
|
cylinder boundaries.
|
|
.Pp
|
|
If you are installing to a SCSI disk, you don't need to worry about the
|
|
details of the geometry. Just create a disklabel based on the total
|
|
number of sectors available on the disk.
|
|
.Pp
|
|
.Em A quick note about partitions:
|
|
Since the target disk will become the boot
|
|
disk for your new
|
|
.Nx*M
|
|
installation, you will need to treat the
|
|
.Sq Li a
|
|
and
|
|
.Sq Li c
|
|
partitions in a special manner. Due to the size of the
|
|
.Nx*M
|
|
boot program (it spills into the area after the disklabel),
|
|
it is necessary to offset the beginning of the
|
|
.Sq Li a
|
|
partition. For HP-IB disks, it is best to offset it by one cylinder from
|
|
the beginning of the disk. For SCSI disks, just offset it by 100 KB (200
|
|
sectors). Later, the
|
|
.Sq Li c
|
|
partition will be marked with the type
|
|
.Sq Li boot
|
|
and may not be used for a file system. (For those unfamiliar
|
|
with historic
|
|
.Bx
|
|
partition conventions, the
|
|
.Sq Li c
|
|
partition is defined as the
|
|
.Sq entire disk ,
|
|
or the
|
|
.Sq raw partition . )
|
|
.Pp
|
|
Here is a table of recommended partition sizes for a full install:
|
|
.Bl -column -offset indent Partition Suggested Needed
|
|
.It Partition Ta Suggested Ta Needed
|
|
.It /\ (root) Ta "25 MB" Ta "15 MB"

|
.It /var Ta "20 MB" Ta "5 MB"
|
|
.It swap Ta Em "2-3 *RAM" Ta 6 MB
|
|
.El
|
|
.Pp
|
|
.(Note
|
|
You will need at least a 6 MB swap partition if you are unable to netboot
|
|
the installer, as the miniroot is temporarily placed in this partition.
|
|

.Ss2 Installing the bootstrap program locally
|
|
.
|
|
For earlier models incapable of netbooting, you need to install the
|
|
bootstrap program on a bootable local device, such as a hard disk, floppy
|
|
disk, or tape drive. If you will be booting the miniroot over the
|
|
network, then you will be installing
|
|
.Pa installation/misc/SYS_UBOOT .
|
|
.Pp
|
|
If you do not have access to a netboot server to serve the miniroot
|
|
installer, you can use a primitive bootstrap program
|
|
.Pa installation/misc/SYS_INST
|
|
to load the miniroot from a locally attached device (such as a
|
|
disk, tape or CD-R). This is not recommended, as
|
|
.Pa SYS_INST
|
|
is difficult to use, buggy, and provides no error checking when
|
|
partitioning your disk.
|
|
.Pp
|
|
If your system has SCSI, this is easy. Just take a
|
|
scratch SCSI disk (hard disk, zip disk, or CD-R) and use any computer
|
|
to dump the bootstrap program to it. For example, to dump it to the
|
|
.Li sd1
|
|
disk on a non-i386 platform:
|
|
.(disp
|
|
.No # Ic "dd if=SYS_UBOOT of=/dev/sd1c"
|
|
.disp)
|
|
.Pp
|
|
If your system has a floppy drive, you can write the bootstrap program to
|
|
it using any computer with a floppy drive. You will need to dump it using
|
|
a utility like
|
|
.Ic rawrite
|
|
or
|
|
.Xr dd 1 .
|
|
Make sure to read back from the floppy to verify that the file has been
|
|
written correctly.
|
|
.Pp
|
|
If your system does not have SCSI or a floppy drive, you will need a
|
|
bootable operating system on your \*M so you can write files to the HP-IB
|
|
device. You should probably write the bootstrap program to the disk you
|
|
will be installing
|
|
.Nx
|
|
onto.
|
|
.Pp
|
|
Using
|
|
.Tn HP-UX
|
|
to write to an HP-IB disk:
|
|
.(disp
|
|
.No # Ic "dd if=SYS_UBOOT of=/dev/rdsk/IDs0"
|
|
.disp)
|
|
.(item
|
|
.Em ID
|
|
is the HP-IB address (a.k.a. slave) of the disk in hexadecimal.
|
|
This is usually between
|
|
.Li 00
|
|
and
|
|
.Li 07 ,
|
|
but possibly up to
|
|
.Li 1F
|
|
(31 decimal) .
|
|
.item)
|
|
.Pp
|
|
Using
|
|
.Tn HP-UX
|
|
to write to an HP-IB tape:
|
|
.(disp
|
|
.No # Ic "dd if=SYS_UBOOT of=/dev/rmt/0mnb obs=20b conv=sync"
|
|
.disp)
|
|
.
|
|
.Ss2 Installing the miniroot filesystem locally
|
|
.
|
|
This step is only necessary if you are not loading the miniroot
|
|
installer from a netboot server.
|
|
Follow the same procedure for the bootstrap program, except use the
|
|
uncompressed miniroot filesystem
|
|
.No ( Pa installation/miniroot/miniroot.fs.gz No )
|
|
instead of the bootstrap program.
|
|
The only quirk is that you should place it at the offset of the swap
|
|
partition you calculated above in the disklabel. In the example disklabel
|
|
above, the offset is 38178 sectors of 512 bytes. Therfore, the
|
|
.Xr dd 1
|
|
command would be something like:
|
|
.(disp
|
|
.No # Ic "gunzip miniroot.fs.gz"
|
|
.No # Ic "dd if=miniroot.fs of=/dev/rdsk/IDs0 seek=38178b"
|
|
.disp)
|
|
Note the
|
|
.Sq Li b
|
|
after the offset, which specifies blocks of 512 bytes.
|
|
.Pp
|
|
By dumping the miniroot to disk where the swap partition will be, you're
|
|
saving a step later where
|
|
.Pa SYS_INST
|
|
tries to download the miniroot over NFS. Just make sure that when you
|
|
enter the partition table into
|
|
.Pa SYS_INST
|
|
you use the same block offset for the swap partition as you dumped the
|
|
miniroot.
|
|
.
|
|
.Ss2 Configuring the netboot server
|
|
.
|
|
This step will configure your netboot server to provide
|
|
.Pa SYS_UBOOT
|
|
and the miniroot installer to your \*M.
|
|
.Pp
|
|
.so ../common/netboot
|
|
.
|
|
.Ss2 Put Series 400 systems in "HP-UX Compatible Boot Mode"
|
|
.
|
|
Series 400 systems can be configured to boot either
|
|
.Tn HP-UX
|
|
or
|
|
.Tn DomainOS .
|
|
To boot
|
|

|
|
you must have your system configured in

.Ss2 Searching for a bootable system
|
|
.
|
|
All the early hp300 Boot ROMs are very primitive and only allow a few
|
|
simple operations. You can only interact with it after it is first powered
|
|
on. If you reboot the machine, it will ignore anything you type and
|
|
start loading the same OS you previously booted.
|
|
.Pp
|
|
At any time after it recognizes the keyboard, while it is doing its self
|
|
test or searching for a bootable system, you can hit reset to return it to
|
|
a cold-boot configuration. On HIL keybaords, this is
|
|
.Key control-shift-break ,
|
|
where
|
|
.Key break
|
|
is the key in the upper left (where
|
|
escape is on sane keyboards). There is no equivalent over serial terminal,
|
|
you'll need to power-cycle your machine.
|
|
.Pp
|
|
After it beeps (i.e. recognizes the HIL keyboard), press
|
|
.Key RETURN

twice to get the list of bootable devices.

.Ss2 Selecting ethernet port on Series 400
|
|
.
|
|
Series 400 machines have two ethernet media types built into the

motherboard. You may only use one at a time. When your Series 400

|
workstation goes through the self-test when powered on or rebooted, it
|
|
will say one of the following:

.Pp
|
|
If the wrong type of network is selected, you will need to change the
|
|
ethernet port. You will need to open the case (4XXt, 4XXdl, 4XXe) or
|
|
remove the motherboard (4XXs) to access the jumper. Be sure to use
|
|
static-prevention measures, as you could easily fry your motherboard from
|
|
carelessness. If you are uncomfortable with this, ask a friend who is
|
|
aware of these issues. There is a block of 8 jumpers at the rear of the
|
|
motherboard, labeled AUI/Thin. You will need to put the jumpers in the
|
|
position necessary for your type of ethernet.

This step is necessary
|
|
.Em only
|
|
if you cannot netboot.
|
|
.Pp
|
|
Chose
|
|
.Li SYS_INST
|
|
from the list of bootable devices that the BootROM found.
|
|
.Li SYS_INST
|
|
will load and prompt you for a command.
|
|
.Pp
|
|
.Em A quick note about disk numbers:
|
|
While in the
|
|
.Pa SYS_INST
|
|
program, you may use different unit numbers for the disks than when the
|
|
.Nx
|
|
kernel is running. The unit number for a disk while in
|
|
.Pa SYS_INST
|
|
is calculated with the following formula:
|
|
.Pp
|
|
.(disp
|
|
unit = (controller * 8) + slaveID
|
|
.disp)
|
|
.Pp
|
|
Controllers are numbered 0, 1, ... starting with the lowest select code.
|
|
SCSI controllers and HP-IB controllers are counted separately. Therefore,
|
|
if you had a system with an internal HP-IB interface at select code 7,
|
|
a fast HP-IB interface at select code 14, and a SCSI interface at select
|
|
code 16, unit numbers might be something like the following:
|
|
.Bl -column -offset indent HP-IB\ at\ 14,\ slaveID\ 5 Unit (disk:\ rd13)
|
|
.It Sy Location Ta Sy Unit
|
|
.It HP-IB\ at\ 7,\ slaveID\ 2 Ta 2 Ta (disk:\ rd2)
|
|
.It HP-IB\ at\ 14,\ slaveID\ 5 Ta 13 Ta (disk:\ rd13)
|
|
.It SCSI\ at\ 16,\ slaveID\ 0 Ta 0 Ta (disk:\ sd0)
|
|
.El
|
|
.Pp
|
|
You will need to place a disklabel on the disk.
|
|
.Pp
|
|
.(disp
|
|
.No "sys_inst\*>" Ic disklabel
|
|
.disp)
|
|
.(Note
|
|
It may be worth selecting the
|
|
.Sy zap
|
|
option initially to ensure that
|
|
the disklabel area is clear. This may be especially important if an
|
|
HP-UX boot block had been previously installed on the disk.
|
|
.Note)
|
|
.Pp
|
|
Select the
|
|
.Sy edit
|
|
option, and answer the questions about your disk.
|
|
There may be several questions which you may not be sure of the answers
|
|
to. Listed below are guidelines for SCSI and HP-IB disks:
|
|
.Pp
|
|
.Bl -column -offset indent -compact Track-to-track?xx xxxxx
|
|
.It Bad\ sectoring? Ta NO
|
|
.It Ecc? Ta NO
|
|
.It Interleave? Ta 1
|
|
.It Trackskew? Ta 0
|
|
.It Cylinderskew? Ta 0
|
|
.It Headswitch? Ta 0
|
|
.It Track-to-track? Ta 0
|
|
.It Drivedata\ 0-4? Ta 0\ (for\ all\ Drivedata\ values)
|
|
.El
|
|
.Pp
|
|
Next, you will be asked to fill out the partition map. You must provide
|
|
responses for all 8 partitions.
|
|
Remember, you must have the sector offset for the
|
|
.Sq Li b
|
|
partition match the location you dumped the miniroot filesystem image.
|
|
Set the size and
|
|
offset of any unused partition to 0. Note that sizes and offsets are
|
|
expressed in
|
|
.Sq n sectors ,
|
|
assuming 512 byte sectors. Care should be taken
|
|
to ensure that partitions begin and end on cylinder boundaries (i.e. size
|
|
and offset is an even multiple of the number of sectors per cylinder).
|
|
While this is not technically necessary, it is generally encouraged.
|
|
.Pp
|
|
.(Note
|
|
When setting the partition type of the
|
|
.Sq Li b
|
|
partition, make sure to
|
|
specify it as an
|
|
.Li ffs
|
|
partition so that the miniroot can be mounted (even
|
|
if this will be a swap partition). You will be given a chance to clean
|
|
this up later in the installation process.
|
|
.Note)
|
|
.Pp
|
|
Once you have edited the label, select the
|
|
.Sy show
|
|
option to verify that it is correct.
|
|
If so, select
|
|
.Sy write
|
|
and
|
|
.Sy done .
|
|
Otherwise, you may re-edit the label.
|
|
.Pp
|
|
In an earlier step, we already copied the miniroot image to the target
|
|
disk.
|
|
.Pp
|
|
Boot from the miniroot file system.
|
|
.Pp
|
|
.(disp
|
|
.No "sys_inst\*>" Ic boot
|
|
.disp)
|
|
.Pp
|
|
Enter the disk from which to boot. The kernel in the miniroot file system
|
|
will be booted into single-user mode.
|
|
.
|
|
.Ss2 Chosing a kernel location
|
|
.
|
|
Once the bootstrap program
|
|
.Li SYS_UBOOT
|
|
has started, it will pause and let you chose a kernel location, name, and
|
|
options:
|
|
.(disp
|
|
\*>\*> NetBSD/hp300 Primary Boot, Revision 1.13

|
|
Boot: [[[le0a:]netbsd][-a][-c][-d][-s][-v][-q]] :-
|
|
.disp)
|
|
.Pp
|
|
If your kernel is on a different device than
|
|
.Li SYS_UBOOT
|
|
then you will need to type in where to find it. This is the case, for
|
|
example, if your model is incapable of netbooting and you started
|
|
.Li SYS_UBOOT
|
|
from a floppy, and the miniroot installer is on a netboot server.
|
|
In this case, you'd type in
|
|
.Sq Li le0
|
|
at the prompt.
|
|
.Pp
|
|
If you've installed the miniroot on your disk, you can always boot from
|
|
that by using partition
|
|
.Sq Li b
|
|
when prompted by
|
|
.Li SYS_UBOOT .
|
|
For example, to boot the miniroot from an HP-IB disk on controller 0 at
|
|
slave ID 2, you'd type:
|
|
.(disp
|
|
.No "Boot: [[[rd0a:]netbsd][-a][-c][-d][-s][-v][-q]] :- " Ic "rd2b:netbsd"
|
|
.disp)
