Precision 7520 rs232 problem after bios upgrade

I have see that after a firmware upgrade, rs232 on the docking station eport II advanced disappear and Windows not recognized anymore.

I have tested with bios 1.8.4, 1.9.0 and also 1.9.1 and both present the same problem.

After downgrade to 1.7.1 rs232 port reappear.

@Franz78,

We've replicated this issue here at Dell technical support so I'm now passing this on to Dell engineering for response.

I will be back with updates in the future. Feel free to send me a PM if you'd like a case number.
