BIOSBOOT(8) - System Manager’s Manual (amd64) # BIOSBOOT(8) - System Manager’s Manual (amd64)
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-Alpha BOOT_ALPHA(8) - System Manager’s Manual (alpha) # BOOT_ALPHA(8) - System Manager’s Manual (alpha)
NAME # boot_alpha - Alpha system bootstrapping procedures
DESCRIPTION # Cold starts # When powered on, the SRM firmware will proceed to its initialization, and will boot an operating system if the auto_action variable is set to “boot” or “restart”, or will wait for interactive commands if set to “halt”.
Warm starts # After a panic, or if the system is rebooted via reboot(8) or shutdown(8), the SRM console will only restart the system if the auto_action variable is set to “boot”.

NAME # boot_amd64 - amd64 system bootstrapping procedures
DESCRIPTION # Cold starts # The Athlon64 computers and clones will perform a POST (Power On Self Test) upon being booted cold. This test will find and initialize memory, keyboard, and other devices. It will search for and initialize any extension ROMs that are present, and then attempt to boot the operating system from an available boot drive.
