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.

CD(4) - Device Drivers Manual # CD(4) - Device Drivers Manual
NAME # cd - ATAPI and SCSI CD-ROM driver
SYNOPSIS # cd* at scsibus? #cd0 at scsibus0 target 6 lun 0 (fixed-configuration example)
DESCRIPTION # The cd driver provides support for ATAPI and SCSI CD-ROM (Compact Disc Read-Only Memory) drives, via scsibus(4). In an attempt to look like a regular disk, the cd driver synthesizes a partition table, with one partition covering the entire CD-ROM.

DISKLABEL(5) - File Formats Manual # DISKLABEL(5) - File Formats Manual
NAME # disklabel - disk pack label
SYNOPSIS # #include <sys/disklabel.h>
DESCRIPTION # Each disk or disk pack on a system may contain a disk label which provides detailed information about the geometry of the disk and the partitions into which the disk is divided. It should be initialized when the disk is formatted, and may be changed later with the disklabel(8) program.

disklabel -w [-Acdnv] [-T file] disk disktype [packid]
disklabel -e [-Acdnv] [-TÂ file] disk
disklabel -E [-Acdnv] [-F|-f file] [-T file] disk
disklabel -R [-nv] [-F|-f file] disk protofile
DESCRIPTION # The disklabel utility can be used to install, examine, or modify the label on a disk drive or pack.

DISKMAP(4) - Device Drivers Manual # DISKMAP(4) - Device Drivers Manual
NAME # diskmap - disklabel UID mapping interface
SYNOPSIS # #include <sys/dkio.h>
DESCRIPTION # The diskmap driver provides userland applications with a means to map a disklabel UID to an actual device and open that device in one atomic operation. This is achieved via the DIOCMAP ioctl(2) command.
The ability to use a disklabel UID is helpful in situations where a disk may appear to the operating system under different device names.

DISKTAB(5) - File Formats Manual # DISKTAB(5) - File Formats Manual
NAME # disktab - disk description file
DESCRIPTION # disktab is a simple database which describes disk geometries and disk partition characteristics. It is used to initialize the disk label on the disk. The format is patterned after the termcap(5) terminal database. Entries in disktab consist of a number of colon (’:’) separated fields. The first entry for each disk gives the names which are known for the disk, separated by “|” characters.

DUMPFS(8) - System Manager’s Manual # DUMPFS(8) - System Manager’s Manual
NAME # dumpfs - dump file system information
SYNOPSIS # dumpfs [-m] filesys | device
DESCRIPTION # dumpfs prints out the super block and cylinder group information for the file system or special device specified, unless -m is specified. The listing is very long and detailed.
dumpfs is useful mostly for finding out certain file system information such as the file system block size, minimum free space percentage, and the file system level that can be upgraded with the -c option of fsck_ffs(8).
