1.6.5 IDE Interface (Bus Master Capability and Synchronous DMA Mode )
Master mode enhanced IDE controller with dual channel DMA engine and interlaced dual
channel commands. Dedicated FIFO coupled with scatter and gather master mode
operation allows high performance transfers between PCI and IDE devices. In addition to
standard PIO and DMA mode operation. The VT82C686B also supports the UltraDMA-33,
UltraDMA-66, and UltraDMA-100 (ATA-100) standards. The IDE controller is SFF-8038I
v1.0 and Microsoft Windows-family compliant.
1.6.6 USB
Universal Serial Bus controller is USB v1.1 and Universal HCI v1.1 compliant. The
VT82C686B includes the root hub with four function ports with integrated physical layer
transceivers. The USB controller allows hot plug and play and isochronous peripherals to
be inserted into the system with universal driver support. The controller also implements
legacy keyboard and mouse support so that legacy software can run transparently in a
non-USB-aware operating system environment.
1.6.7 Ethernet
1.6.7.1 Realtek RTL8101L Ethernet Controller
The Realtek RTL8101L is a highly integrated and cost-effective single-chip Fast Ethernet
controller. Featuring an MC'97 interface, the device is able to provide a combo-solution for
LAN and software modem applications. It is equipped with a PCI and Boot ROM share
interface (Realtek patent pending) for both EPROM and Flash Memory to provide
maximum network security and ease of management.
The RTL8101L offers an ACPI (Advanced Configuration Power Interface) management
function to provide efficient power management for advanced operating systems with
OSPM (Operating System Directed Power Management). A remote wake-up function is
also provided by support to Magic Packet, Link Change, and Wake-up Frame to increase
cost-efficiency in network maintenance and management. In addition, it supports analog
Auto Power-down and provides an auxiliary power auto-detect function to further save
power.
