Processor
The P4IBMS mainboard uses a mPGA478 Socket
that has the following features:
•
Accommodates Intel Pentium 4 478-pins CPU
•
Supports a system bus (FSB) of 400 MHz
•
Supports 3.2 GB/s data bus bandwidth
Chipset
Intel's innovative i82845 (MCH) and 82801BA
(ICH2) 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 MHz
frontside (system) bus frequency
•
Supports up to 1.5 GB of DRAM (un-buffered
SDRAM)
•
Supports a maximum memory bandwidth of 1
GB/s
•
AGP controller is AGP 2.0 compliant and sup-
ports 2x/4x Fast Write Protocol (1.5V only)
•
PCI IDE controller supports PCI bus master-
ing, PIO modes 0~4, and UDMA 33/66/100
•
Two USB controllers double the bandwidth to
24 Mbps across four ports
•
Integrated AC 97 audio that supports full sur-
round 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 management.
Memory
The mainboard can accommodate 3.3V, un-
buffered, 168 pin DIMM DRAM with a total
capacity of 1.5 GB.
VGA
The P4IBMS includes a 4xAGP slot that provides
four times the bandwidth of the original AGP specifi-
cation. AGP technology provides a direct connection
between the graphics sub-system and the processor
so that the graphics do not have to compete for
processor time with other devices on the PCI bus.
