Motherboard Description 
SY-K7VEMPRO 
11 
is a high integration, high performance, power-efficient, and high 
compatibility device that supports AMD and non-AMD based processor to 
PCI bus bridge functionality to make a complete Microsoft 
PC99-compliant PCI/ISA system In addition to complete ISA extension 
bus functionality, the VT82C686B includes standard AMD ligent 
peripheral controllers: 
1) 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 
standard to allow reliable data transfer rates up to 33MB/sec throughput. 
The VT82C686B also supports the UltraDMA-66 standard. The IDE 
controller is SFF-8038I v1.0 and Microsoft Windows-family compliant. 
2) Universal Serial Bus controller that 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 non-USB-aware operating system 
environment. 
3) Keyboard controller with PS2 mouse support. 
4) Real Time Clock with 256 byte extended CMOS. In addition to the 
standard ISA RTC functionality, the integrated RTC also includes the 
date alarm, century field, and other enhancements for compatibility with 
the ACPI standard. 
5) Hardware monitoring subsystem for managing system/ motherboard 
voltage levels, temperatures, and fan speeds 
6) Full System Management Bus (SMBus) interface. 
7) Two 16550-compatible serial    I/O ports with infrared communications 
port option. A third serial port is available to be dedicated to the IR
