BL20P 1151 error: com port 1 address assignment conflict

I can't seem to get past this error. I've tried to clear vram, but it comes up with the error after the rom message and I can't get past it.

Try to Use System Maintenance Switch enable #1, #5, #6
Power UP and Wait for 2 Minutes, than Power Down move Switches back to OFF and Retry
If it work Try to Proceed with System ROM Update if Needed
