2-1 Mainboard Layout
This mainboard
is designed with VIA Apollo MVP3 AGP/PCIset chipset
which is developed by VIA Corporation to fully support Pentium Processor PCI/
ISA system. By providing a massive increase in the bandwidth available between
the video card and the processor (66MHz), the unique feature of AGP supported by
VIA Apollo MVP3 chipset improves the speed of rendering and texturing for 3D
graphics.The chipset also provides an integrated IDE controller with two high
performance IDE interfaces for up to four IDE devices (hard devices, CD-ROM
device, etc). The Winbond W83877TF Super I/O controller provides the standard
PC I/O function: one floppy interface, two 16 Byte FIFO serial ports and one EPP/
ECP capable parallel port. This mainboard layout is shown in the next page for
user's reference. Care must be taken when inserting memory modules, CPUs or
even plugging PCI card into associated slots to avoid damaging any circuits or
sockets on board. A cooling fan is strongly recommended when installing Pentium/
Pentium MMX/K5/K6/6x86/6x86L/6x86MX/C6 processor due to possible
overheat.
This mainboard supports a minimum of 8MB and a maximum of 384MB of
System Memory while Onboard 512KB cache to increase system performance.
This mainboard supports standard Fast Page, EDO (Extended Data Out or Hyper
This mainboard
Page Mode) or synchronous DRAM.
provides three 168-pin
DIMM sites for memory expansion. The sockets support 1M x 64(8MB), 2M x 64
(16MB), 4M x 64(32MB), and 8M x 64(64MB) single-sided or double-sided
memory modules. The memory timing requires 70 ns Fast page devices or 60 ns
EDO DRAM. (DRAM Modules may be parity [x 36] or non-parity [x 32].
This mainboard supports two Onboard PCI IDE connectors, and automatically
detects IDE harddisk type by BIOS utility automatic.
This mainboard supports Award Plug & Play BIOS for the ISA and PCI cards.
The BIOS can be located in Flash EPROM which can replace BIOS code easily if
necessary.
