It's the chipset that's important, and the PL2303 works on FreeBSD.
cable with the adapter integrated into the connectors is easier to use, 
and the price seems a bit high.

If you can find it, the FTDI chipset is better.  PCI serial cards should 
work also, although I can't recall trying any with FreeBSD.

Before all that, check to see if there is a serial header on the 
motherboard.  Then all you need is a standard DB9 to IDC cable, and any 
computer place should have a box full of those.
