Memory
The mainboard supports DDR 266/333 SDRAM. It
accommodates two unbuffered 2.5V 184-pin slots. Each slot
supports up to 1 GB with a total maximum capacity of 2 GB.
USB
The USB 2.0 Controller is compliant with Universal Serial Bus
Specification Revision 2.0.
The USB 2.0 supports data transfer rates up to 480MB/sec for
high-speed devices and specifies a microframe that will be
th
1/8
of a 1msec frame. This allows the USB 2.0 devices to
have small buffers even at high data rates.
The USB 1.1 connectors and other full speed cables can
support the higher speed of USB 2.0 without any changes.
The chipset has the following advanced USB features:
•
Compliant with Enhanced Host Controller Interface
(EHCI) Specification Revision 0.95 and Universal Host
Controller Interface (UHCI) Specification Revision 1.1
•
PCI multi-function device consists of two UHCI Host
Controllers for full/low-speed signaling and one EHCI Host
Controller core for high-speed signaling
•
Supports PCI-Bus Power Management Interface
Specification release 1.1
•
Legacy support for all downstream facing ports
Graphics
The mainboard includes an AGP slot that provides four times
the bandwidth of the original AGP specification. AGP
technology provides a direct connection between the graphics
sub-system and the processor so that the graphics do not
have to compete for processor time with other devices on the
PCI bus.
AC' 97 Audio
The AC' 97 Audio codec is compliant with the AC 97 2.2
Codec
specification that meets the PC2001 requirements and
supports S/PDIF In/Out. It also has a built-in buffer and internal
PLL. Features include support for analog switch for rear-out
(share), the line-in jack (share), center/bass (share), and MIC
jack to output 6 channels audio.
Note: Optional 4-channel audio controller.
Onboard LAN
The Realtek RTL8100B LAN chip is incorporated in the chipset
(optional)
providing the mainboard with integrated Ethernet PCI LAN
capabilities.
Expansion
The mainboard comes with the following expansion options:
Options
•
Three 32-bit PCI slots
•
One AGP slot
•
A Communications and Network Riser (CNR) slot (AC97
interface only)
•
Two IDE channels and a floppy disk drive interface
The mainboard supports Ultra DMA bus mastering with
transfer rates of 33/66/100/133 MB/sec.
•
Fully support provisions of IEEE1394-1995 for High-
IEEE 1394A
Performance Serial Bus and the P1394a draft 2.0
Controller
standard
Interface
•
Provides one compliant cable port at 100Mbits/s,
(optional)
200Mbits/s, and 400Mbits/s
•
Supports arbitrated short bus reset to improve utilization
of the bus
