Memory Map

A collection of structures that defines the layout and allocation of system
memory during the boot process. Drivers and applications that run during the
boot process prior to OS control may require memory. The boot services
implementation is required to ensure that an appropriate representation of
available and allocated memory is communicated to the OS as part of the hand-
off of control.

Memory Type

One of the memory types defined by EFI for use by the firmware and EFI
applications. Among others, there are types for boot services code, boot services
data,

runtime services

code, and runtime services data. Some of the types are

used for one purpose before

ExitBootServices()

is called and another

purpose after.

Messaging Device Path

A Device Path that is used to describe the connection of devices outside the

Coherency Domain

of the system. This type of node can describe physical

messaging information (e.g., a SCSI ID) or abstract information (e.g., networking
protocol IP addresses).

Miscellaneous Services

Various functions that are needed to support the

EFI

environment. Includes

InstallConfigurationTable()

,

ResetSystem()

,

Stall()

,

SetWatchdogTimer()

,

GetNextMonotonicCount()

, and

GetNextHighMonotonicCount()

.

MTFTP

See

Multicast Trivial File Transfer Protocol

.

Multicast Trivial File Transfer Protocol (MTFTP)

A protocol used to download a

Network Boot Program

to many clients

simultaneously from a

TFTP

server.

Name Space

In general, a collection of device paths; in an EFI Device Path.

Native Code

Low level instructions that are native to the host processor. As such, the
processor executes them directly with no overhead of interpretation. Contrast this
with

EBC

, which must be interpreted by native code to operate on a

VM

.

NBP

See

Network Bootstrap Program

or

Network Boot Program

.

Network Boot Program

A remote boot image downloaded by a

PXE

client using the

Trivial File

Transfer Protocol

or the

Multicast Trivial File Transfer Protocol

. See

Network Bootstrap Program
