Introduction
Thank you for choosing the RS482-M motherboard. This motherboard is a high perfor-
mance, enhanced function motherboard that supports Socket 939 AMD Sempron/Athlon
64/Athlon 64 FX CPUs for high-end business or personal desktop markets.
The motherboard incorporates the RS482 Northbridge (NB) and SB400 Southbridge (SB)
chipsets. The Northbridge supports the HyperTransport (HT) interface speeds up to
2000MT/s data rate. RS482 integrated an ATI RADEON X300-based graphics core, coupled
with a high speed HyperTransport interface for optimal 3D performance. This motherboard
supports two DDR Sockets with maximum memory size of 2 GB. One PCI Express x16 slot,
intended for Graphics Interface, is fully compliant to the PCI Express Base Specification
revision 1.0a.
The SB400 Southbridge supports three PCI slots which are PCI 2.3 compliant. It imple-
ments an EHCI compliant interface that provides 480Mb/s bandwidth for eight USB 2.0
ports (rear panel x 4, header x 4). Two onboard IDE connectors supports 4 IDE devices in
UDMA 133/100/66/33 mode. The Southbridge integrates a Serial ATA host controller that
is SATA v1.0 compliant, supporting four SATA ports with maximum transfer rate up to 150
MB/s each.
The RS482-M motherboard is equipped with advanced full set of I/O ports in the rear panel,
including PS/2 mouse and keyboard connectors, COM1, LPT1, VGA, four USB ports, one
optional LAN port, and audio jacks for microphone, line-in and line-out.
