FIPS 151-1
The Federal Information Processing Standard that specifies the requirements for conformance to
an older draft of POSIX.1 (IEEE Std. 1003.1-1988) than the version adopted as ISO/IEC IS
9945-1:1990 and imposes some additional requirements.
FIPS 151-2
The Federal Information Processing Standard that specifies the requirements for conformance to
POSIX.1 as ISO/IEC IS 9945-1:1990 and imposes some additional requirements.
FIR
See FRU information record (FIR).
FIRINIT
A diagnostic task used to update the communications line interface processor (CLIP) FRU information
record (FIR) that is kept in the ServerNet wide area network (SWAN) concentrator communications
line interface processor (CLIP) flash memory.
FIRMUP
A diagnostic task used to update the copy of the Portable Silicon Operating System (pSOS) system
product embedded kernel that is kept in the ServerNet wide area network (SWAN) concentrator
communications line interface processor (CLIP) flash memory.
firmware
Code in memory that is necessary for the power-up initialization and communication with a host
or device. The software for components of the ServerNet architecture (for example, an adapter) is
called firmware. Some firmware for ServerNet components is downloaded when the system or
component is loaded.
fixed process configuration
Using Subsystem Control Facility (SCF) to configure a generic process to always start in the first
available processor (that is, to be fault tolerant).
flag
In a UNIX or Open System Services (OSS) command, a character sequence that begins with a
hyphen and is processed as a unit.
flash memory
A type of memory that contains essential firmware and nonessential firmware.
flash PROM
A type of programmable read-only memory (PROM) that is electrically reprogrammable.
flat segment
A type of logical segment. Each flat segment has its own distinct address range within the process
address space that never overlaps the range of any other allocated segments. Thus all allocated
flat segments for a process are always available for use concurrently. See also logical segment
and selectable segment.
