The MBR (Master Boot Record) resides on the first sector of the disk and is where control is passed to by the machine BIOS.

The MBR will be different from operating system to operating system, and each operating system will have a way of writing its own MBR.

For example, in Windows

Code:
 
fdisk /mbr

(google that for syntax) will write an MBR and on Solaris the

Code:
 
installboot

command will write an MBR.

If an MBR exists at all when the disk comes from the factory, that will just be from the manufacturing test process and probably won't be what you need for your O/S. When the O/S install routine runs it will install its MBR.

pc-sysinstall -- System installer backend SYNOPSIS
pc-sysinstall [-c file] [command] DESCRIPTION
The pc-sysinstall utility is a hybrid backend for installing FreeBSD. When run in install mode it takes a configuration file and performs an installation according to the parameters specified in the configuration file. When called with one of the system query commands it provides information about the system to aid a front end in building an appropriate configuration file. The following options are available: -c file Perform an installation as directed by file. COMMANDS
The command can be any one of the following: help Display a list of all commands. help command Display the help data for the specified command. disk-list Provide a listing of the storage devices detected on this system. disk-part disk Queries the specified storage device and returns information about its partitions. disk-info disk Returns information about a storage device's size, cylinders, heads, and sectors. detect-laptop Tests to see if this system is a laptop or desktop. detect-emulation Tests to see if this system is running in an emulator detect-nics Returns a listing of the detected network cards on this system. list-components Returns a listing of the available components which can be installed. list-rsync-backups user host port Returns a listing of available rsync-backups on the target server in the life-preserver/ directory. list-tzones Returns a listing of available timezones. query-langs Returns a list of languages that the installer supports. sys-mem Returns the size of installed system RAM in MegaBytes. test-netup test if an internet connection is available. update-part-list Returns a list of PC-BSD and FreeBSD installs on this system for updates. xkeyboard-layouts Returns a list of keyboard layouts that xorg supports. xkeyboard-models Returns a list of keyboard models that xorg supports. xkeyboard-variants Returns a list of keyboard variants that xorg supports. create-part disk size Create a new MBR primary slice on the target disk using size MB. delete-part partition Delete the disk partition specified. If this is the last partition, the disk partition layout will also be scrubbed, leaving a clean disk ready for MBR or GPT file system layouts. start-autoinstall file Start an automated installation with the specified file. Normally only used by automated install scripts. setup-ssh-keys user host port Setup SSH without a password for the target host, user, and port. Used to prompt the user to log into a server before doing a rsync + ssh restore. HISTORY
This version of pc-sysinstall first appeared in FreeBSD 9.0. AUTHORS
Kris Moore <kmoore@FreeBSD.org> BUGS
This utility was written to install PC-BSD and has seen limited use as an installer for FreeBSD. It's likely that usage to install FreeBSD will expose edge cases that PC-BSD doesn't, as well as generate feature requests based on unforeseen needs. BSD
