2.6 Integrated Peripherals

The V7865 incorporates an SMSC Super I/O (SIO) chip. The SIO provides the
V7865 with two 16550 UART-compatible serial ports, keyboard and mouse ports
and general purpose I/O for system monitoring functions. The serial port signals
for COM1 are available from the front panel, and the signals for COM2 are
available through the rear I/O.
The SATA interface is provided by the Intel I/O Controller Hub (ICH7-M) chip.
The SATA interface supports two channels known as the primary and secondary
channels. The IDE channel is routed onboard to the optional CompactFlash
socket. Both SATA channels are routed out the VME backplane and can be
accessed using a ACC-0602RC/ACC-0603RC RTM which terminates into standard
SATA connectors.
