ing 2x, 4x, and 8x mode transfers, SideBand Addressing, Flush/Fence
commands and pipelined grants.
The VT8235 Southbridge supports standard intelligent peripheral controllers
such as USB v2.0/1.1 and Universal HCI v2.0/1.1 compliant, real time clock
with 256 byte extended CMOS, integrated bus-mastering dual full-duplex di-
rect-sound AC97 link compatible sound system and full System Management
Bus (SMBus) interface.
The L7VTA is equipped with advanced full set of I/O ports, such as dual
channel IDE interfaces, a floppy controller, two high-speed serial port, an
EPP/ECP capable bi-directional parallel port connector, four USB (Universal
