+.Sh SYNOPSIS
+.Nm boot
+.Sh DESCRIPTION
+.Ss Power fail and crash recovery
+Normally, the system will reboot itself at power-up or after crashes.
+An automatic consistency check of the file systems will be performed
+as described in
+.Xr fsck 8 ,
+and unless this fails, the system will resume multi-user operations.
+.Ss Cold starts
+The prep architecture does not allow the direct booting of a kernel from the
+hard drive.  Instead it requires a complete boot image to be loaded.  This
+boot image contains a
+.Nx
+kernel, which will then provide access to the devices on the machine.  The
+image can be placed on any device that the firmware considers a bootable
+device.  Usually this is either a SCSI disk, tape, CD-ROM, or floppy drive.
+.Ss Boot program options
+The prep architecture and bootloader does not support any option parsing at
+the boot prompt.
+.Ss Boot partition
+The prep port requires a special boot partition on the primary boot device
+in order to load the kernel.  This partition consists of a PC-style i386
+partition label, a small bootloader, and a kernel image.  The prep firmware
+looks for a partition of type 0x41 (65) and expects the bootloader, immediately
+followed by the kernel, to be there.
+The
+.Xr mkbootimage 8
+command needs to be used to generate this image.
