with 16 MB up to 128 MB of memory, and can be single-sided or double sided.
However, total installed memory must not exceed 256 MB. If you install a double-
sided module in either DIMM 2 or DIMM 3, you cannot install any memory module in
the other socket. DIMM1 is independent and does not have this limitation.
Highly Integrated Design
This mainboard features a high level of integrated functions provided by the onboard
chipsets. The Intel 82443EX provides all the north bridge support – CPU and memory
addressing, PCI-IDE controller, and PCI-bus interface. In addition, the 82443EX
provides a complete AGP graphics controller solution. The Intel 82371EB provides
the south bridge support – ACPI power management, real-time clock, and USB
interface. The Winbond W83977EF is a single chip I/O solution, and the Elite PCI
Audio-CMI8338 provides the onboard 3D audio feature. Hardware monitoring is
supported by the GL520SM. This highly integrated mainboard ensures stability and
allows a fully functional system to be created by adding just a processor, a graphics
adapter and memory.
Built-in PCI 3D Sound
The Elite PCI Audio-CMI8338 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 speakers and also supports SPDIF 24-bit
digital sound input and output.
Solid Expansion Options
Because this is a highly integrated board with built-in audio and a full set of I/O ports,
it does not require a full set of expansion slots. The board provides three usable slots.
The board has three 32-bit PCI slots and one 8/16-bit ISA slot. The ISA slot is shared
with one of the PCI slots meaning that you can use either the ISA slot or the PCI slot,
but not both at the same time. PCI1 and PCI3 share a request line. This means that
only one of these slots can support a bus-mastering PCI expansion card.
Integrated I/O
Using the Winbond W83977EF I/O chip and the Intel 82443EX/82371EB chipset, the
board has a comprehensive set of integrated I/O ports. The I/O port array features PS/2
keyboard and mouse ports, a parallel port, two USB ports, two serial ports, a
game/MIDI port, and three audio jacks. Optionally, you can use the built-in mainboard
header to add in an infrared port. The mainboard has two PCI-IDE channels and a
floppy disk drive interface.
