Chapter 1 Introduction
1-1 Main Board Overview
The main board is a new-generation AGP Pentium® main board with high
performance in rendering and texture for 3D Graphics. Based on Apollo MVP3
chipset, the main board
has intergrated the latest advances in processor, memory,
I/O technologies into an AT form factor. It is also designed for the upcoming 100
MHz F.S.B CPUs, like AMD K6-2/K6-3 series or Cyrix MII CPUs.
The main board utilizes VIA Apollo MVP3 and supports new architects such as
high-speed AGP graphic port, SDRAM, Ultra DMA/33, bus master IDE and USB
port. It has three Dual In-line Memory Modules (DIMM) which can be installed
with SDRAM memory. The memory subsystem supports up to 512Mbyte SDRAM
of non-buffered 3.3V using standard 168-pin DIMM sockets.
The main board implements high performance I/O Controller utilizes with fully
Plug and Play device which supports 2.88 MB Floppy, Dual 16550 Compatible
(with 16 bytes FIFO, up to 460K baud rate) Serial Port, ECP (Enhanced
Capabilities Port), EPP (Enhanced Parallel Port) parallel port, Infrared IrDA
(HPSIR), and Amplitude Shift Keyed IR. (ASKIR) port.
The main board supports 3*PCI & 3*ISA for highest performance I/O add-on
adapter cards. The system board supports three Matrix Independent for complete
multiple PCI adapters operation up to 133MB/s data transfer rate on PCI bus
compared to 33MB/s on EISA bus, synchronized operation CPU to PCI Interface
for best graphical performance, 120MB/s PCI to system DRAM together with
utilizing Snoop Ahead Features, and support back to back sequential CPU to PCI
Memory writes to PCI Burst Write for full PCI through put.
