PCIe X-1 Serial Card & Dell 630s

Long story short.. I have a older Dell 630s which has been my work horse
computer for the last few years, I got a new system and now I am
re-assigning the 630s, (replacing a older home built 1ghz system) .

I need to add a DB9 Serial port

I have tried two different brand/makes of USB -> Serial cables but I could
not get the device drivers to load and work with the serial home automation
device software as it seems that the cable did not have enough voltage to
push the commands to the home automation devices, as my older systems
built-in serial connector.

I then purchased a 'Low Profile' PCI DB25 card, but when I install this card
the system would not boot...

...system would power up but would not get the BIOS screen.

So I could only guess that the card itself is bad {It was suggested a bad
BIOS?}

So it was suggested that I try a PCIe x1 serial card.

Does anybody have and experence with PCIe x1 cards?

I am thinking of purchasing the following card from the "SuperMediaStore"
     Brand: SYBAMPN
     Part#: SD-PEX15022
