Processor
The L4IBME mainboard uses a mPGA478 Socket that has the
following features:
•
Accommodates Intel/P4 Willamette/Northwood 478-pins
CPU
•
Supports a system bus (FSB) of 400/533 MHz
•
Supports 3.2GB/s / 4.2GB/s data bus bandwidth
Chipset
Intel's innovative i82845E (MCH) and 82801DB (ICH4) chip-
sets are based on an innovative and scalable architecture with
proven reliability and performance. A few of the advanced
features of the chipsets are:
•
Support a Single Processor With a Data Transfer-Rate of
400/533MHZ
•
Support DDR-SDRAM at 200/266MHz Operation
(DDR200/266)
•
Supports AGP 2.0 Including 1X/2X/4X AGP Data Trans-
fers and 2X/4X Fast Write Protocol.
•
Maximum DRAM Address Decode Space of 4GB.
•
Support for Symmetrical and Asymmetrical DRAM ad-
dressing
•
PCI Rev. 2.2, 3.3V (5V Tolerant), 33 MHz Interface Com-
pliant
•
PCI to System Memory Data Streaming Up to
132Mbyte/Sec
•
2 Channel Ultra ATA/100 Bus Master IDE Controllers.
•
Six USB 2.0 Ports for Serial Transfers at 480Mbits /Sec
Max.
•
Integrated AC 97 audio that supports full surround sound
with up to six channels
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 two unbuffered 2.5V 184 pin slots with a DRAM
size of up to 512 MB and 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)
•
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 L4IBME supports Ultra DMA bus mastering with transfer
rates of 33/66/100 MB/sec.
