Thanks for your reply. The only *driver* of Moschip is to set the
serial port to the PCI
(http://www.moschip.com/data/products/NM/linux.zip).

I don't know the exact model of the PCI chipset (Nm9715, Nm9755,
Nm9805, Nm9820, Nm9835, Nm9845, etc)
http://www.moschip.com/html/data_sheets.html

I don't have a JTAG debugger, I also don't have Angel Debug Monitor. I
can only load the sample program to the LPC2114. If nothing comes out,
then I don't know what's wrong. Probably I'll have to tell my boss
about this mission impossible when he come back...
