+.Dt BOOT 8 macppc
+.Os
+.Sh NAME
+.Nm boot ,
+.Nm boot.conf
+.Nd macppc-specific bootstrap
+.Sh DESCRIPTION
+The main purpose of this program is to load the system kernel.
+.Pp
+As described in
+.Xr boot_macppc 8 ,
+this program is loaded by the
+firmware
+and provides a convenient way to load the kernel.
+This program acts as an enhanced boot monitor for macppc systems, providing
+a common interface for the kernel to start from.
+.Pp
+Basic operations include:
+.Pp
+.Bl -bullet -compact
+.It
+Loading kernels from hard disk.
+.It
+Loading kernels compressed by
+.Xr gzip 1 .
+.It
+Providing an interactive command line.
+.El
+.Pp
+The sequence of its operation is as follows: initialization,
+parsing the configuration file, then an interactive command line.
+While at the command line you have 5 seconds to type any commands, if needed.
+If time expires, the kernel will be loaded according to
+the current variable settings (see the
+.Nm set
+command).
+Each time a kernel load fails, the timeout is increased by one second.
+The sequence of
+.Nm
+operations is as follows:
+.Bl -enum
+.It
+If the file
+.Pa /etc/boot.conf
+.\" XXX BEWARE! wd0 only, so text change...
+.\" exists on the filesystem
+.\" .Nm
+.\" was loaded from, open and parse it.
+exists on the filesystem in slice
+.Sq a
+on the first disk drive
+.Pq wd0 ,
+open and parse it.
+This file may contain any commands
+.Nm
+accepts at the interactive prompt.
+Though default settings usually suffice, they can be changed here.
+.\" XXX CHECK_SKIP_CONF is not defined...
+.\" .Pp
+.\" .Pa boot.conf
+.\" processing can be skipped by holding down either Control key as
+.\" .Nm
+.\" starts.
+.It
+The header line
+.Pp
+.Dl >> OpenBSD/macppc BOOT [x.xx]
+.Pp
+is displayed to the active console, where
+.Ar x.xx
+is the version number of the
+.Nm
+program, followed by the
+.Pp
+.Dl boot>
+.Pp
+prompt, which means you are in interactive mode and may enter commands.
+If you do not,
+.Nm
+will proceed to load the kernel with the current parameters after the
+timeout period has expired.
+.El
+.Pp
+By default,
+.Nm
+attempts to load the kernel executable
+.Pa /bsd .
+If it fails to find the kernel and no alternative kernel image has
+been specified, the system will be unable to boot.
+.Sh COMMANDS
+The following commands are accepted at the
+.Nm
+prompt:
+.Bl -tag -width shorten
+.It boot Op Ar image Op Fl acds
+Boots the kernel image specified by
+.Ar image
+with any options given.
+Image specification consists of a pair
+.Ar device : Ns Ar filename ;
+either or both can be omitted (`:' is not needed if both are omitted),
+in which case values from
+.Nm
+variables will be used.
+.Pp
+The only bootable devices, at the moment, are IDE devices connected to
+the internal controller;
+they are detected as
+.Sq wd
+devices.
+Therefore, to boot kernel
+.Pa /bsd
+from slice
+.Sq a
+on the first hard drive,
+specify
+.Dq boot wd0a:/bsd .
+.Bl -tag -width _a_
+.It Fl a
+Causes the kernel to ask for the
+.Nm root
+device to use.
+.It Fl c
+Causes the kernel to go into
+.Xr boot_config 8
+before performing
+.Xr autoconf 4
+procedures.
+.It Fl d
+Causes the kernel to drop into
+.Xr ddb 4
+at the earliest convenient point.
+.It Fl s
+Causes the kernel to boot single-user.
+.El
+.It echo Op Ar args
+Displays
+.Ar args
+on the console device.
+.It help
+Prints a list of available commands.
+.It ls Op Ar directory
+Prints contents of the specified
+.Ar directory
+in long format including: attributes and file type, owner, group,
+size, filename.
+.It reboot
+Reboots the machine by initiating a warm boot procedure.
+.It set Op Ar varname Op Ar value
+If invoked without arguments, prints a list of variables and their values.
+If only
+.Ar varname
+is specified, displays contents of that variable.
+If
+.Ar varname
+and
+.Ar value
+are both specified, sets that variable to the given value.
+Variables include:
+.Pp
+.Bl -tag -compact -width boothow
+.It Nm addr
+Address at which to load the kernel.
+.It Nm debug
+Debug flag if
+.Nm
+was compiled with DEBUG defined.
+.It Nm device
+Boot device name (e.g.,
+.Li wd0a ,
+.Li wd1a ) .
+.It Nm howto
+Options to pass to the loaded kernel.
+.It Nm image
+File name containing the kernel image.
+.It Nm timeout
+Number of seconds boot will wait for human intervention before
+booting the default kernel image.
+.\" .It Nm tty
+.\" Active console device name (e.g.,
+.\" .Li com0 ) .
+.\" Currently, only the first serial port
+.\" .Pq Li com0
+.\" is supported for console on macppc.
+.El
+.\" XXX ignored, so don't document it.
+.\" .It stty Op Ar device Op Ar speed
+.\" Displays or sets the
+.\" .Ar speed
+.\" for a console
+.\" .Ar device .
+.\" If changing the baudrate for the currently active console,
+.\" .Nm
+.\" offers you five seconds of grace time before committing the change
+.\" to allow you to change your terminal's speed to match.
+.\" If changing speed
+.\" .Em not
+.\" for the active console, the baudrate is set for the
+.\" .Em next
+.\" time you switch to a serial console.
+.\" .Pp
+.\" The default baudrate is 9600bps.
+.It time
+Displays system time and date.
+.El
+.Sh FILES
+.Bl -tag -width /etc/boot.conf -compact
+.It Pa /usr/mdec/boot
+system bootstrap
+.It Pa /etc/boot.conf
+system bootstrap's startup file
+.It Pa /bsd
+kernel image
+.It Pa /bsd.rd
+kernel image for installation/recovery
+.El
+.Sh EXAMPLES
+Boot the default kernel:
+.Pp
+.Dl boot> boot
+.Pp
+Remove the 5 second pause at boot-time permanently, causing
+.Nm
+to load the kernel immediately without prompting:
+.Pp
+.Dl # echo \&"boot\&" > /etc/boot.conf
+.Pp
+Boot the kernel named
+.Pa /bsd
+from the second hard disk in
+.Dq User Kernel Configuration
+mode (see
+.Xr boot_config 8 ) .
+This mechanism allows for the explicit enabling and disabling of devices
+during the current boot sequence, as well as the modification
+of device parameters.
+Once booted, such changes can be made permanent by using
+.Xr config 8 Ns 's
+.Fl e
+option.

+.Dl boot> boot wd1a:/bsd -c

+This program was written by Michael Shalayeff for
+.Ox 2.1
+on the i386 platform, and was later ported to the macppc platform.
