Debugging over PCIe to Serial card

WINDBG
1

Hi guys,
I’m trying to kernel debug an XP system on a netbook which comes with no serial port and no firewire.
I’ve bought a mini PCIe to Serial card that feeds off 1x PCIe. The card is based on Oxford 16950 chipset.
I’ve installed it inside the netbook (one spare mini-PCIe) and Windows sees it. I needed to install drivers for a device called multi-port serial adapter and then drivers for the 2 serial ports offered by the card.
I’ve successfully tested the serial connection with a null modem cable with hyperterminal.

However I’ve had no success establishing a kernel debug link at boot time. Windbg simply does not connect to the target.

So I’m turning to the community, hoping others have tried to do the same thing. Any words of advice?

Thanks!

Addition:
The drivers needed by the card are marked as start-on-demand. I’ve tried modifying the StartType to start-on-boot but still no joy.

Kd doesn’t recognize any serial ports other than the traditional BIOS
defined ones - I don’t think that it will work with your card.

If you must go the add in route, I’d get a 1394 card:

Good luck,
