interface. 

8) Integrated PCI-mastering dual full-duplex direct-sound 

AC97-link-compatible sound system. Hardware soundblaster-pro and 
hardware-assisted FM blocks are included for Windows DOS box and 
real-mode DOS compatibility. Loopback capability is also implemented 
for directing mixed audio streams into USB and 1394 speakers for high 
quality digital audio 

9) Two game ports and One MIDI port 
10)  ECP/EPP-capable parallel port 
11)  Standard floppy disk drive interface 
12)  Distributed DMA capability for support O ISA legacy DMA over the 

PCI bus. Serial IRQ is also supported for docking and non-docking 
application. 

13)  Plug and Play controller that allows complete steerability of all PCI 

interrupts and internal interrupts/ DMA channels to any interrupt 
channel. One additional steerable interrupt channel is provided to allow 
plug and play and reconfigurability of onboard peripherals for Windows 
family compliance. 

The VT82C686B also enhances the functionality of the standard ISA 
peripherals. The integrated interrupt controller supports both edge and 
level triggered interrupts channel by channel. The integrated DMA 
controller supports type F DMA in addition to standard ISA DMA modes. 
Compliant with the PCI2.2 specification, the VT82C686B supports 
delayed transactions and remote power management so that slower ISA 
peripherals do not block the traffic of the PCI bus. Special circuitry is built 
in to allow concurrent operation without causing dead lock even in a 
PCI-to PCI bridge environment. The chip also includes eight levels 
(doublewords) of line buffers from the PCI bus to the ISA bus to further 
enhance overall system performance. 

The motherboard uses the VT82C686B Super-I/O controller which 
features:
