AUTOCONF(4) - Device Drivers Manual (amd64) # AUTOCONF(4) - Device Drivers Manual (amd64)
NAME # autoconf - diagnostics from the autoconfiguration code
DESCRIPTION # When OpenBSD bootstraps it probes the innards of the machine on which it is running and locates controllers, drives, and other devices, printing out what it finds on the console. This procedure is driven by a system configuration table which is processed by config(8) and compiled into each kernel.

NAME # biosboot - amd64-specific first-stage system bootstrap
DESCRIPTION # This small program (roughly 512 bytes of code) is responsible for loading the second-stage boot(8) program (typically /boot), which in turn will load the kernel.
biosboot must be installed by installboot(8). As part of the installation, installboot(8) patches biosboot with information about the location of boot(8) on disk.

Boot BOOT(8) - System Manager’s Manual (amd64) # BOOT(8) - System Manager’s Manual (amd64)
NAME # boot, boot.conf - amd64-specific second-stage bootstrap
DESCRIPTION # The main purpose of this program is to load the system kernel while dealing with the pitfalls of the PC BIOS architecture.
As described in boot_amd64(8), this program is loaded by the biosboot(8) primary bootstrap loader and provides a convenient way to load the kernel. This program acts as an enhanced boot monitor for PC systems, providing a common interface for the kernel to start from.

NAME # cdboot - amd64-specific second-stage CD-specific bootstrap
DESCRIPTION # cdboot is a modified version of the amd64 second-stage bootstrap program, boot(8), configured to be run by the OpenBSD El Torito CD-ROM boot sector cdbr. cdboot will look for an /etc/boot.conf configuration file on the CD-ROM. If it finds one, it processes the commands within it. boot.

NAME # fdisk - partition table maintenance program
SYNOPSIS # fdisk [-evy] [-A | -g | -i | -u] [-b blocks[@offset[:type]]] [-l blocks | -c cylinders -h heads -s sectors] [-f file] disk
DESCRIPTION # fdisk creates and edits MBR and GPT partition tables. These tables are used by the boot process of some platforms to find the OpenBSD kernel and, when present, are used by the kernel to find the disklabel(5).

PXEBOOT(8) - System Manager’s Manual (amd64) # PXEBOOT(8) - System Manager’s Manual (amd64)
NAME # pxeboot - amd64-specific second-stage PXE bootstrap
DESCRIPTION # pxeboot is a modified version of the amd64 second-stage bootstrap program, boot(8), configured to run under Intel’s Preboot Execution Environment (PXE). PXE is a form of smart boot ROM, built into many Ethernet cards from Intel, 3Com, and other manufacturers.
The computer’s PXE boot ROM contacts a DHCP server by broadcasting a request on the network.
