Event
An EFI data structure that describes an “event” — for example, the expiration of a timer.
Event Services
The set of functions used to manage events. Includes
CheckEvent()
,
CreateEvent()
,
CloseEvent()
,
SignalEvent()
, and
WaitForEvent()
.
FAT
See File Allocation Table .
FAT File System
The file system on which the EFI file system is based. See File Allocation Table and
System Partition .
File Allocation Table (FAT)
A table that is used to identify the clusters that make up a disk file. File allocation tables
come in three flavors: FAT-12, which uses 12 bits for cluster numbers; FAT-16, which
uses 16 bits; and Fat-32, which allots 32 bits, but only uses 28 (the other 4 bits are
reserved for future use).
File Handle Protocol
A component of the File System Protocol . It provides access to a file or directory. Also
called the EFI File Handle Protocol .
File System Protocol
A protocol that is used during boot services to obtain file-based access to a device. It has
two parts, a
Simple File System Protocol that provides a minimal interface for file-type
access to a device, and a File Handle Protocol that provides access to a file or directory.
Firmware
Any software that is included in read-only memory (ROM).
GUID (Globally Unique Identifier)
A 128-bit value used to differentiate services and structures in the boot services
environment. The format of a GUID is defined in Appendix A. See
Protocol .
GUID Partition
A contiguous group of sectors on an EFI Hard Disk .
GUID Partition Table
A data structure that describes a GUID Partition . It consists of an GUID Partition
Table Header and, typically, at least one GUID Partition Entry . There are two
partition tables on an EFI Hard Disk : the Primary Partition Table (located in block 1 of
the disk) and a Backup Partition Table (located in the last block of the disk). The Backup
Table is a copy of the Primary Table.
