Processor
The mainboard uses a micro PGA 478-pin socket that has the
following features:
•
Accommodates Intel/P4 Willamette/Northwood 478-pins
CPU
•
For L4IBMG - Supports 400/533MHz front side bus (FSB)
and data bandwidths up to 4.2 GB/s.
•
For L4IBMGL - Supports 400MHz front side bus (FSB)
and data bandwidths up to 3.2 GB/s.
Chipset
Intel's innovative 845-G/845-GL (GMCH) and 82801DB (ICH4)
chipsets are based on an innovative and scalable architecture
with proven reliability and performance. A few of the advanced
features of the chipsets are:
•
Host interface controller supports 400/533 MHz front side
(system) bus frequency
•
Supports system bus Dynamic Bus Inversion (DBI).
•
Supports 133 MHz SDR SDRAM or 266 MHz DDR
SDRAM devices
•
AGTL+ Host Bus with Integrated Termination supporting
32-Bits host addressing.
•
Supports AGP 2.0 including 1X/2X/4X AGP data transfers
and 2X/4X Fast Write Protocol
•
Supports 3D / 2D graphic
•
Supports up to 2 double-sided DIMM (4 device rows)
•
PCI Rev. 2.2, 3.3V (5V Tolerant), 33 MHz interface com-
pliant and PCI to System Memory Data Streaming up to
132 MB/sec
•
Upstream Hub Interface for access to the Intel GMCH.
•
2 Channel Ultra ATA/100 Bus Master IDE Controllers
•
Supports six USB 2.0 ports for serial transfers at
480Mbits/sec
Additional key features include support for an AC 97 link for audio
and modem, hardware monitoring, and ACPI/OnNow power man-
agement.
Memory
The mainboard can accommodate 2.5V DDR SDRAM. It ac-
commodates three unbuffered 2.5V 184 pin slots with a total
maximum capacity of 2 GB.
AC' 97 Audio
The AC' 97 Audio codec is compliant with the AC' 97 2.2
Codec
specification, and supports 18-bit ADC (Analog Digital Con-
verter) and DAC (Digital Analog Converter) resolution as well
as 18-bit stereo full-duplex codec with independent and vari-
able sampling rates.
Expansion
The mainboard comes with the following expansion options:
Options
•
Three 32-bit PCI slots
•
One 4xAGP slot (support 1.5V only) for L4IBMG main-
board only
•
Two IDE connectors which support four IDE channels and
a floppy disk drive interface
•
One Onboard LAN (optional) chip and LAN port on top of
the USB port
The mainboard supports Ultra DMA bus mastering with trans-
fer rates of 33/66/100 MB/sec.
