.Em Introduction
.Pp
Using
.Ic sysinst ,
installing
.Nx
is a relatively easy process. You
still should read this document and have it in hand when doing the
installation process. This document tries to be a good guideline
for the installation and as such covers many details to be completed.
Do not let this discourage you, the install program is not hard
to use.

.It
.Em Possible Tn PCMCIA Em issues
.Pp
Machines with
.Tn PCMCIA
slots may have problems during installation. With the improvements of
the
.Tn PCMCIA
code in this release, this will not happen very frequently.
If you do not have
.Tn PCMCIA
on your machine
.Tn ( PCMCIA
is only really used on laptop machines),
you can skip this section, and ignore the
.Dq Bq Tn PCMCIA
notes. If you do have
.Tn PCMCIA
in your machine, you can safely ignore this section and the
.Dq Bq Tn PCMCIA
the first time, as you are likely to not have problems. Should troubles
occur during floppy boot, they may be
.Tn PCMCIA
specific. You should then re-read this section and try again,
following the instructions in the
.Dq Bq Tn PCMCIA
notes.
.Pp
This section explains how to work around the installation problem.
.Pp
The kernel keeps careful track of what interrupts
and I/O ports are in use during autoconfiguration. It then allows
the
.Tn PCMCIA
devices to pick unused interrupts and I/O ports.
Unfortunately, the
.Tn Li INSTALL
kernel may not detect all devices in your system. This may
be because the
.Tn Li INSTALL
kernel only supports the minimum set of devices to install
.Nx
on your system, or it may be that
.Nx
does not have support for the device causing the conflict.
.Pp
For example, suppose your laptop has a
soundblaster device built in; the
.Tn Li INSTALL
kernel has no sound support. The
.Tn PCMCIA No code might allocate your soundblaster's
.Tn IRQ No and I/O ports to
.Tn PCMCIA
devices, causing them not to work, or to lock up the system. This is
especially bad if one of the devices in question is your ethernet
card.
.Pp
As of
.Nx 1.5 ,
the kernel attempts to probe for available interrupts that are
usable by the
.Tn PCIC
.Tn ( PCMCIA
interrupt controller). Assuming that this functions correctly, it
should alleviate interrupt conflicts; however, I/O port conflicts are
still possible.
.Pp
This problem will impact some, but not all, users of
.Tn PCMCIA .
If this problem is affecting you, watch the
.Dq Bq Tn PCMCIA
notes that will appear in this document.
.if r_i386 \{\
.Pp
It can be difficult to distinguish an interrupt conflict from
an I/O space conflict. There are no hard-and-fast rules, but
interrupt conflicts are more likely to lock up the machine,
and I/O space conflicts are more likely to result in misbehavior
(e.g. a network card that cannot send or receive packets).
.Pp
The kernel selects a free interrupt according to a mask of allowable
interrupts, stored in the kernel global variable
.Va pcic_isa_intr_alloc_mask .
This mask is a logical-or of power-of-2s of allowable interrupts:
.(disp
IRQ  Val     IRQ  Val     IRQ  Val      IRQ  Val
  0  0x0001    4  0x0010    8  0x0100    12  0x1000
  1  0x0002    5  0x0020    9  0x0200    13  0x2000
  2  0x0004    6  0x0040   10  0x0400    14  0x4000
  3  0x0008    7  0x0080   11  0x0800    15  0x8000
.disp)
.Pp
For example, 0x0a00 allows both IRQ 9 and IRQ 11. By default,
the
.Tn Li INSTALL
kernel permits all IRQs other than IRQs 5 and 7, so the corresponding
mask is 0xff5f. The
.Tn Li GENERIC
kernel, however, allows all IRQs. (The presumption here
is that IRQ 10 may be assigned to a device that the
.Tn Li GENERIC
kernel
supports, but that the
.Tn Li INSTALL
does not.) Because of support for interrupt probing, it is no
longer necessary to exclude IRQs 3 and 5 explicitly; if they are
in use, they should not be assigned to
.Tn PCMCIA .
.Pp
The kernel selects IO space by assigning cards IO space within a
predefined range.  The range is specified as a base and size,
specified by the kernel global variables
.Va pcic_isa_alloc_iobase
and
.Va pcic_isa_alloc_iosize .
For systems with 12-bit addressing (most systems), the kernel defaults to a
base of 0x400 and a size of 0xbff (a range of 0x400-0xfff).
For systems with 10-bit addressing, the kernel defaults to a
base of 0x300 and a size of 0xff (range of 0x300-0x3ff).
.Pp
Unfortunately, these ranges may conflict with some devices. In the
event of a conflict, try a base of 0x330 with a size of 0x0bf (range
of 0x330-0x3ff).
.Pp
In order to work around this at installation time, you may
boot the
.Tn Li INSTALL
kernel with
.Ic boot Fl d ,
in order to enter
.Xr ddb 4
(the in-kernel debugger), and then use the
.Ic write
command to alter the variable values:
.Pp
.Dl db> Ic "write pcic_isa_intr_alloc_mask 0x0a00"
.Dl "pcic_isa_intr_alloc_mask            0xff5f = 0xa00"
.Dl db> Ic "write pcic_isa_alloc_iobase 0x330"
.Dl "pcic_isa_alloc_iobase               0x400 = 0x330"
.Dl db> Ic "write pcic_isa_alloc_iosize 0x0bf"
.Dl "pcic_isa_alloc_iosize               0xbff = 0xbf"
.Dl db> Ic "continue"
.Pp
Note that, since some floppy images may not have symbol information in
the kernel, you may have to consult the matching
.Pa .symbols
file in the
.Pa binary/kernel
directory in the installation tree. Find the pcic_ symbols used above,
look at the hexadecimal value in the first column, and write, for
example (if
.Va pcic_isa_intr_alloc_mask
is equal to c0513e3c):
.Pp
.Dl db> Ic "write 0xc0513e3c 0x0a00"
.Pp

After installation, this value can be permanently written to the kernel image
directly with:
.Pp
.Dl # Ic "cp /netbsd /netbsd.bak"
.Dl # Ic "gdb --write /netbsd"
.Dl (gdb) Ic "set pcic_isa_intr_alloc_mask=0x0a00"
.Dl (gdb) Ic "set pcic_isa_alloc_iobase=0x330"
.Dl (gdb) Ic "set pcic_isa_alloc_iosize=0x0bf"
.Dl (gdb) Ic "quit"
.Dl #
.Pp
or you could specify these value when configuring your kernel, e.g.:
.(disp
options PCIC_ISA_INTR_ALLOC_MASK=0x0a00
options PCIC_ISA_ALLOC_IOBASE=0x330
options PCIC_ISA_ALLOC_IOSIZE=0x0bf
.disp)
.Pp
If you can
get your
.Tn PCMCIA
card to work using this hack, you may also ignore the
.Bq Tn PCMCIA
notes later in this document.
.Pp
We hope to provide a more elegant solution to this problem in a future
.Nx
release.

.Em General
.Pp
The following is a walk-through of the steps you will take while
getting
.Nx
installed on your hard disk.
.Ic sysinst
is a menu driven
installation system that allows for some freedom in doing the
installation. Sometimes, questions will be asked and in many cases
the default answer will be displayed in brackets
.Pq Dq \&[\ ]
after the question. If you wish to stop the installation, you may press
.Key CONTROL-C
at any time, but if you do, you'll have to begin the installation
process again from scratch, by running the 
.Pa /sysinst
program from the command prompt, you do not need to reboot.
.It
.Em Quick install
.Pp
First, let's describe a quick install. The other sections of
this document go into the installation procedure in more
detail, but you may find that you do not need this. If you
want detailed instructions, skip to section 3. This section
describes a basic installation, using a CD-ROM install as
an example.

After this, you will be presented with the current values
stored in the MBR, and will be given the opportunity to
change, create or delete partitions. For each partition
you can set the type, the start and the size. Setting the type to

will delete a partition. You can
also mark a partition as active, meaning that this is
the one that the BIOS will start from at boot time.
.Pp
Be sure to mark the partition you want to boot from as active!
.Pp
After you are done editing the MBR, a sanity check
will be done, checking for partitions that overlap.
Depending on the BIOS capabilities of your machine and the
parameters of the
.Nx
partition you have specified, you
may also be asked if you want to install newer bootcode in
your MBR. If you have multiple operating systems on the
disk that you are installing on, you will also be given
the option to install a bootselector, that will allow you
to pick the operating system to start up when your computer

part of the disk that you can pick from:
.Ic Standard, Standard with X
and
.Ic Custom .
The first two use a set of default
values (that you can change) suitable for a normal
installation, possibly including X. The last option
lets you specify everything yourself.
.Pp
You will be presented with the current layout of the
.Nx
disklabel, and given a chance to change it.
For each partition, you can set the type, offset and size,
block and fragment size, and the mount point. The type
that
.Nx
uses for normal file storage is called
.Sy 4.2BSD .
A swap partition has a special type called
.Sy swap .

You can also specify a partition as type
.Sy MSDOS .
This is useful if you share the disk with
.Tn MS-DOS

.Tn Windows ;
.Nx
is able to access the files on these partitions.
You can use the values from the MBR for the
.Tn MS-DOS
part of the disk to specify the partition of type

of installing the sets. Some of these methods will first
load the sets on your hard disk, others will extract the sets
directly.
.Pp
For all these methods, the first step is making the sets
available for extraction, and then do the actual installation.

To be able to install using ftp, you first need to configure
your network setup, if you haven't already at the start of
the install procedure.

to provide some data, like IP address, hostname, etc. If you
do not have name service set up for the machine that you
are installing on, you can just press
.Key RETURN

.Pp
You will also be asked to specify the host that you want
to transfer the sets from, the directory on that host,
the account name and password used to log into that
host using ftp, and optionally a proxy server to use.
If you did not set up DNS when answering
the questions to configure networking, you will need to
specify an IP address instead of a hostname for the ftp
server.

.Ic sysinst
will proceed to transfer all the default set files
from the remote site to your hard disk.

To be able to install using NFS, you first need to configure
your network setup, if you haven't already at the start of
the install procedure.
.Ic sysinst

to provide some data, like IP address, hostname, etc. If you
do not have name service set up for the machine that you
are installing on, you can just press
.Key RETURN
in answer to these questions, and DNS will not be used.
.Pp
You will also be asked to specify the host that you want
to transfer the sets from, and the directory on that host
that the files are in. This directory should be mountable
by the machine you are installing on, i.e. correctly
exported to your machine.
.Pp
If you did not set up DNS when answering the questions to
configure networking, you will need to specify an IP address
instead of a hostname for the NFS server.

When installing from a CD-ROM, you will be asked to specify
the device name for your CD-ROM player
.Pq usually Li cd0 ,
and the directory name on the CD-ROM where the distribution files are.

.Em Extracting the distribution sets
.Pp
After the install sets containing the
.Nx
distribution
have been made available, you can either extract all the
sets (a full installation), or only extract sets that
you have selected. In the latter case, you will be shown the
currently selected sets, and given the opportunity to select
the sets you want. Some sets always need to be installed
.Pq Sy kern, base No and Sy etc
they will not be shown in this selection menu.
.Pp
Before extraction begins, you can elect to watch the files being
extracted; the name of each file that is extracted will be shown.
This can slow down the installation process considerably, especially
on machines with slow graphics consoles or serial consoles.
.Pp
After all the files have been extracted, all the necessary
device node files will be created. If you have already
configured networking, you will be asked if you want to
use this configuration for normal operation. If so, these
values will be installed in the network configuration files.
The next menu will allow you to select the time zone that you're in,
to make sure your clock has the right offset from UTC. 
Finally you can set a password for the "root" account, to prevent 
the machine coming up without access restrictions.
