FGlossary_ADR
A reserved name in ACPI name space. It refers to an address on a bus that has standard
enumeration. An example would be PCI, where the enumeration method is described in
the PCI Local Bus specification.
_CRS
A reserved name in ACPI name space. It refers to the current resource setting of a
device. A _CRS is required for devices that are not enumerated in a standard fashion.
_CRS is how ACPI converts non standard devices into plug and play devices.
_HID
A reserved name in ACPI name space. It represents a device’s plug and play hardware
ID and is stored as a 32-bit compressed EISA ID. _HID objects are optional in ACPI.
However, a _HID object must be used to describe any device that will be enumerated by
the ACPI driver in the OS. This is how ACPI deals with non Plug and Play devices.
_UID
A reserved name in ACPI name space. It is a serial number style ID that does not change
across reboots. If a system contains more than one device that reports the same _HID,
each device must have a unique _UID. The _UID only needs to be unique for device that
have the exact same _HID value.
ACPI
Refers to the Advanced Configuration and Power Interface Specification and to the
concepts and technology it discusses. The specification defines a new interface to the
system board that enables the operating system to implement operating system-directed
power management and system configuration.
ACPI Device Path
A Device Path that is used to describe devices whose enumeration is not described in an
industry-standard fashion. These devices must be described using ACPI AML in the
ACPI name space; this type of node provides linkage to the ACPI name space.
Big Endian
A memory architecture in which the low-order byte of a multibyte datum is at the highest
address, while the high-order byte is at the lowest address. See Little Endian.
BIOS
Basic Input/Output System. A collection of low-level I/O service routines.
