EFIMTA: EFI M odular T est A rchitecture.
EFI Shell: The EFI (Extensible Firmware Interface)
Shell is a simple, interactive user interface that
allows EFI device drivers to be loaded, EFI
applications to be launched, and operating systems
to be booted. In addition, the EFI Shell provides a
set of basic commands used to manage files and
the system environment variables. See Shell.
EMI: E lectro– M agnetic I nterference.
EPROM: E rasable P rogrammable R ead- O nly
M emory. A type of memory device that is used to
store the system BIOS code. This code is not lost
when the computer is powered off.

ESD: E lectro S tatic D ischarge. An undesirable
discharge of static electricity that can damage
equipment and degrade electrical circuitry.
Event: The generation of a message (event
message) by a software component and that is
directed to the Event Manager.
Event address: Defines the destination for a
message sent over a specified event channel. An
address is one of: the name of a history file (for the
HISTORY channel), an e–mail address (for the
EMAIL channel), the name of a user group (for the
WEB channel), the SNMP Manager IP address (for
the SNMP channel).
Event channel: Defines how the Event Manager
sends an event message. An event channel is one
of: HISTORY (the message is logged in a history
file), EMAIL (the message is sent to an e–mail
address), WEB (the message is stored for analysis
from the PAM web user interface), SNMP (the
message is sent as an SNMP trap to the selected
SNMP application).
Event filter:
A list of selected messages among all
possible event messages. If an event message is
not included in the filter, the Event Manager
discards the message.
Event Manager:
A PAM feature used to forward
event messages over a configured event channel.
See Event.
Event message: A message sent by a software
component to the Event Manager for routing to a
destination that is configured by an administrator.
Event subscription: An object that defines the
event channel, address, and filter for sending an
event message. If no such object is defined, the
event message is discarded.
F
Fail–over: Failover is a backup operational mode
in which the functions of a system component
(such as a processor, server, network, or database,
for example) are assumed by secondary system
components when the primary component
becomes unavailable through either failure or
scheduled down time.
FAME: F lexible A rchitecture for M ultiple

nvironments.
FAST WIDE: A standard 16–bit SCSI interface
providing synchronous data transfers of up to 10
MHz, with a transfer speed of 20M bytes per
second.
FC: F ibre C hannel.
FCAL: F ibre C hannel A rbitrated L oop.
FCBQ: F an C ontrol B oard for Q BB.
FCBS: F an C ontrol B oard for S PS.
FDA: F ibre D isk A rray.
FDD: F loppy D isk D rive.
Flash EPROM: Flash Erasable Programmable
Read-Only Memory. A type of memory device that
is used to store the the system firmware code. This
code can be replaced by an updated code from a
floppy disk, but is not lost when the computer is
powered off. An EPROM containing the system
firmware.
Firewall: A set of related programs, located at a
network gateway server, that protects the
resources of a private network from users from
other networks.
Firmware: an ordered set of instructions and data
stored to be functionally independent of main
storage.
Format: The process used to organize a hard or
floppy disk into sectors so that it can accept data.
Formatting destroys all previous data on the disk.
FPB: F AME P ower B oard (FAME: Flexible
Architecture for Multiple Environments).
