Motherboard Description
SY-7VMA-B
17
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 VT83C686B 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.
