High-performance Memory
The board has three DIMM sockets for the installation of 168-pin, 3.3V non-buffered
DIMM memory modules. The DIMM memory modules must be installed with
SDRAM memory chips. The board supports a memory bus of 100 MHz, so you must
install high-performance PC-100 memory modules. Each installed memory module
can be populated with 16 MB up to 512 MB of memory, so a total of 1.5 GB of
memory can be installed. The integrated video system uses a shared memory
architecture so that you must reserve some of the installed memory as video memory
using the system BIOS. You must install at least one memory module, and the first
memory module is installed in DIMM1.
Highly Integrated Design
This mainboard features a high level of integrated functions provided by the onboard
chipsets. The SiS 620 Pentium-II PCI/AGP/3D VGA chipset provides all the north
bridge support – Pentium-II CPU and memory addressing, integrated DRAM
controller, PCI-IDE controller, AGP 3D graphics sub-system, and PCI-bus interface.
The SiS 5595 provides the south bridge support – ACPI-compliant power management,
real-time clock, and USB interface. The Winbond W83877TF is a single chip I/O
solution, and the CMI8738 provides the onboard 3D audio feature. This highly
integrated mainboard ensures stability and allows a fully functional system to be
created by adding just a processor and memory.
Built-in AGP 3D-Graphics
This mainboard features a built-in 3D-graphics controller integrated in the SIS 620
chipset. The graphics controller uses a shared memory architecture that allows it use
either 2 MB, 4 MB, or 8 MB of the system's main memory. The graphics controller
has hardware accelerators for both 3D and 2D graphics and an MPEG decoder for
DVD video playback. The graphics system will support extended high-resolution
displays up to 1600 x 1200. At an XGA resolution of 1024 x 768, the graphics system
supports a color depth of 16 million colors.
Built-in PCI 3D Sound
The CMI8738 is a single chip solution for PCI-bus 3D audio. The chip provides Sound
Blaster 16-bit-compatible audio, plus support for Microsoft's DirectSound 3D
specification and Aureal A3D interface. The sound ports include jacks for speakers,
microphone and stereo in, and a game/MIDI port. The audio system supports full
duplex operation and drivers are available for WIN 95/98 and WIN NT 4.0. The audio
system can output sound to 4 loudspeakers and also supports SPDIF 24-bit digital
sound input and output.
Optional Built-in Communications
The mainboard has an integrated fax/modem connector. As an option, you can
purchase a fax/modem extension bracket which connects the line and telephone RJ11
