Hi Eric,

If the board has the serial port available, then yes you should
be able to talk to the processor over the serial port - but
only once it is programmed.

So the real question is;

1) How does Moschip expect you to program the device; over PCI,
    or over serial using the bootloader, or both?

2) Does Moschip supply a device driver, or at least enough
    data to write your own driver.

3) What is used as the PCI-to-micro interface, I don't think
    that this chip has an external memory interface, so have
    they made it an SPI or I2C target, or built a bit-bang interface.

4) What is the PCI chipset used on the board; PLX, AMCC, TI?

Send a link to the board data sheet and I'll tell you what I think.
