in error correction (EC), error correction code (ECC), or has no error
correction.
If you are using a Pentium-III/PentiumII processor cartridge that operates
over a 100 MHz system bus, you must install PC-100 compliant memory
modules (memory that operates at 100 MHz). If you install the PPGA
Celeron processor, you can install memory that operates at 66 MHz (you
can install PC-100 memory if you wish, but the system will run the
memory at 66 MHz).
You can install one, two or three modules. Each memory module can
hold a maximum capacity of 128 MB of standard SDRAM chips, or 256
MB of registered SDRAM chips so maximum memory capacity is 384
MB of standard SDRAM memory or 768 MB registered SDRAM memory.
Highly Integrated Design
This board uses the VIR ET82C693A/596B chipset. The ET82C693A
forms the north bridge and supports system buses of 66 , 100 and
133MHz. It is AGP Rev. 1 compliant and supports 3.3v AGP devices
operating over a 66/133 MHz bus. The memory bus supports the fastest
access (X-1-1-1) for 66 MHz ,100MHz and 133MHz operation. The
board is compliant with PCI Rev.2.1 operating at 33 MHz Four PCI Bus
masters are supported.
The south bridge is provided by the 596B. This chip supports ACPI
(Advanced Configuration and Power Interface) Rev 1.0, onboard PCI
IDE channels(DMA66), USB ports, and a System Management Bus for
OS control and configuration of devices.
Built-in PCI 3D Sound
The PCI Audio CMI 8738 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 RJII sockets to the board. The fax/modem supports
the V.90 protocol that allows transmissions at up to 56Kbps and is fully
