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
