CHARACTERISTIC OF OTHER MOTHERBOARD
LAYOUT TYPE
 Motherboard Divided into three types by main
components size, shape and overall layout.
 AT Motherboard
 ATX Motherboard
 NLX Motherboard
AT MOTHERBOARD
 This is the traditional style, which are two types
"Baby AT" and "Full AT.“
 The Common two identify characteristics of AT
Style Motherboard.
 Two sets of 6-pin power connectors.
 CPU socket placement along with the ISA Slot.
AT MOTHERBOARD
ATX STYLE MOTHERBOARD
 It supports Socket-7, Socket-8 and Scocket-1.
 Most common characteristics of ATX Style
Motherboard
I/O Port Connector has been installed with a
single I/O Panel behind the existing
motherboard.
PS2 Style 20 pin power connector.
CPU away from the other Expansion Position.
ATX MOTHERBOARD
NLX STYLE MOTHERBOARD
• ATX Style Motherboard installed, upgrade and
replacing are trouble but in NLX Motherboard,
these processes are easier.
• This Motherboard is plug-in with the "Raiser
Card.“
NLX MOTHERBOARD
FORM FACTOR OF MOTHERBOARD
 The motherboard form factor describes its
general shape, the type of case and power supply
it can use, and its physical organization (layout of
the motherboard).
 Over time, in the computer industry, we have
had a number of different motherboard form
factors being developed.

FORM
FACTOR
LPX
ATX
AT
 The oldest and the biggest form factor.
 Popular 1992-93.
 The reason that prompted the Baby AT was the
width of the AT (12") and the fact that the
board was difficult to install, service, and
upgrade.
BABY AT
 The Baby AT was the standard in the PC
industry from roughly 1993-1997.
 It is still being used today, usually in Pentium
class products.
ATX
 ATX was developed of improvement:
1. Enhanced ease of use
2. better support for current and future I/O
3. Better support for current and future processor
technology
4. Reduced total system cost.
 The ATX is basically a Baby AT rotated 90 degrees
and providing a new mounting configuration for
the power supply.
ATX (cont…)
 Mini-ATX : This form factor is basically the same as
ATX with a smaller allowable board size
 microATX : developed as a natural evolution of the
ATX form factor to address new market trends and PC
technologies
 FlexATX : A subset of microATX developed by Intel in
1999.
microATX SUPPORT
 Current processor technologies
 The transition to newer processor technologies
 AGP high performance graphics solutions
 Smaller motherboard size
 Smaller power supply form factor
FlexATX
 Supports current socketed processor
technologies
 Smaller motherboard size
 ATX 2.03 I/O panel
 Same mounting holes as microATX
 Socket only processors to keep the size small
LPX
 This is based on a design by Western Digital.
 The expansion slots are on a single riser card
which is mounted onto the planar board.
 allows for smaller cases, but limits the number of
expansion slots, usually to two or three.
 LPX motherboards often have the video adapters
integrated onto the motherboard, and they may
have integrated sound as well.
 LPX is an older form factor (8.67" x 9.25")
NLX
 NLX is a new low profile motherboard form
factor designed to improve upon today’s low
profile form factors and to adapt to new market
trends and PC technologies.
NLX
 Supports

and

 Supports new AGP high performance graphics
solutions
 Supports tall memory technology
