Clock Throttling – South bridge function that allows the CPU clock to be stopped
and started at a known duty cycle using the STPCLK# pin to enter and exit Stop Grant

DIMM (SODIMM) - Dual In-line Memory Module, a small circuit board that holds
memory chips. A Single In-line Memory Module (SIMM) has a 32-bit path to the
memory chips whereas a DIMM has 64-bit path. Because the Pentium processor
requires a 64-bit path to memory, you need to install SIMMs two at a time. With
DIMMs, you can install one DIMM at a time. SODIMM is Small Outline Dual In-line
Memory Module used in notebook computers.

DMI - Desktop Management Interface, an API to enable software to collect
information about a computer environment about a computer environment. For example,
using DMI a program can determine what hardware and expansion boards are installed
on a computer.

GPI - General Purpose Input.
GPO - General Purpose Output.
Lid Switch - A switch that indicates the notebook LCD Panel has been closed and it

MPEG-2 - Moving Picture Experts Group, a working group of ISO. The term also
refers to the family of digital video compression standards developed by the group.
There are two major MPEG standards : MPEG-1 and MPEG-2. The most common
implementations of the MPEG-1 standard provide a video resolution 352x240 at 30
frames per second(fps). A newer standard, MPEG-2, offers resolution of 720x480 and
1280x720 at 60 fps, with full CD-quality audio.

North Bridge - The CPU to PCI interface, also contains the memory and cache
controllers.
South Bridge - The PCI to ISA interface, also contains many legacy devices.
SMM - System Management Mode, Mode of operation while an SMI is active.
SMI - System Management Interrupt, non-maskable interrupt that causes the system

SMB - System Management Bus, that is used for managing smart batteries, reading
SDRAM configuration information, and other miscel1aneous system function.
TBD -To Be Discussed. The mentioned specification is not final that should be
discussed with related engineers.
Ultra DMA-33 - A protocol developed by Quantum Corporation and Intel that
supports burst mode data transfer rates of 33.3 MBps.
USB - A new external bus standard that supports data transfer rates of 12 MBps. A
single USB port can be used to connect up to 127 peripheral devices, such as mice,
modems, and keyboards. USB also supports Plug-and-Play installation and hot plugging.
