BIO(4) - Device Drivers Manual # BIO(4) - Device Drivers Manual NAME # bio - block I/O ioctl tunnel pseudo-device SYNOPSIS # pseudo-device bio [count] DESCRIPTION # The bio driver provides userland applications ioctl(2) access to devices otherwise not found as /dev nodes. The /dev/bio device node operates by delegating ioctl calls to a requested device driver. Only drivers which have registered with the bio device can be accessed via this interface. ...

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_SPARC64(8) - System Manager’s Manual (sparc64) # BOOT_SPARC64(8) - System Manager’s Manual (sparc64) NAME # boot_sparc64 - sparc64 system bootstrapping procedures DESCRIPTION # System starts # When powered on, after a panic, or if the system is rebooted via reboot(8) or shutdown(8), the PROM will proceed to its initialization, and will boot an operating system if autoboot is enabled. Boot process description # The sparc64 boot process is split into two parts: a small first-stage bootblock that is written into the superblock area of a partition (and hence is limited in size to SBSIZE - DEV_BSIZE bytes) , and a second-stage boot program that resides in the filesystem proper. ...
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. ...

SOFTRAID(4) - Device Drivers Manual # SOFTRAID(4) - Device Drivers Manual NAME # softraid - software RAID SYNOPSIS # softraid0 at root DESCRIPTION # The softraid device emulates a Host Bus Adapter (HBA) that provides RAID and other I/O related services. The softraid device provides a scaffold to implement more complex I/O transformation disciplines. For example, one can tie chunks together into a mirroring discipline. There really is no limit on what type of discipline one can write as long as it fits the SCSI model. ...
