This PPAP-3720 system board is eligible with Intel® Xeon processors, and 184-pin DDR DIMM
up to 4GB DDR RAM. The enhanced on-board PCI IDE interface supports 4 drives up to PIO
mode 4 timing and Ultra DMA/100 synchronous mode feature. The on-board super I/O chipset
integrates two serial ports driven by two high performance 16C550-compatible UARTs to
provide 16-byte send/receive FIFOs. Besides, the two Universal Serial Bus ports provide high-
speed data communication between peripherals and PC.
The on-board flash ROM is used to make the BIOS update easier. The high precision Real Time
Clock/Calendar is built to support Y2K for accurate scheduling and storing configuration
information. All of these features make PPAP-3720 excellent in stand-alone applications.
If any of these items is damaged or missing, please contact your vendor and save all packing
materials for future replacement and maintenance.

3.2 System Architecture
The following illustration of block diagram will show you how PPAP-3720 gives you a highly
integrated system solution. The most up-to-date system architecture of PPAP-3720 includes two
main VLSI chips. It contains E7500MCH and ICH3 to support Xeon processor, DDR DIMM, PCI
bus interface, USB port, SMBus communication, and Ultra DMA/100 IDE Master. The on-board
super I/O chip Winbond W83627HF supports two UARTs, FDC, parallel port and hardware
monitoring.
PPAP-3720 has built-in Socket 603/604 to support Intel Xeon processor for cost-effective and
high performance application. However.
The E7500 MCH provides a completely integrated solution for the system controller and data
path components in a Xeon processor system. It provides optimized 64-bit DDR RAM interface.
The ICH3 provides a highly integrated multifunction for the best industry applications. It supports
2-channel dedicated Ultra ATA/33/66/100 IDE master interface, Universal Serial Bus
(USB)
controllers and one 64-bit PCI bus interface.
All detailed operating relations are shown in
Fig. 3-2
