I2C
Two-wire (clock and data) signaling scheme allowing communication
between integrated circuits, primarily used to read and load register values
IDE
A parallel Integrated Device Electronics interface for hard disk drives (also
known as PATA)
Italics
(Sometimes in blue color) emphasizes words in text or documentation, or
chapter titles or web addresses if underlined
Legacy Drive
Relics from the PC-AT computer that is not in use in contemporary PC
systems: primarily the ISA bus, UART-based serial ports, parallel printer
ports, PS-2 keyboards, and mice. Definitions vary as to what constitutes a
legacy device. Some definitions include IDE as a legacy device
LPC
A low-speed pin-count interface is used for peripheral circuits such as Super
I/O controllers, which typically combine legacy-device support into a single
IC
LS
Least Significant
LVDS
Low Voltage Differential Signaling has been widely used as a physical
interface for TFT flat panels. LVDS can be used for many high-speed
signaling applications. In this document, it refers only to TFT flat-panel
applications
MS
Most Significant
NTSC
National Television Standards Committee video broadcast standard used in
North America.
PAL
Phase Alternating Line video broadcast standard used in many European
countries
POST
Power-on Self-Test
PCIE
Next-generation high-speed Serialized I/O bus
PHY
Ethernet controller physical layer device
ROM
Read-Only Memory, a legacy term often the device referred to as a ROM
can be written to, in a special mode. Such writable ROMs are sometimes
called Flash ROMs. UEFI Firmware is stored in ROM or Flash ROM.
RTC
The battery-backed circuit in PC-AT systems keeps system time and date as
well as certain system setup parameters.
