Can''t Find Comm Ports After BIOS Flash
- Thread starter kerrywaz1
- Start date
The USB ports on the back are working (mouse, keyboard), but the com ports are not listed in the Device Manager (COM & LPT). Everything is enabled in the BIOS as far as chipsets. I cleared the RTC RAM using the jumpers and restarted and that didn't help.
If I add a port using the "add legacy hardware", the "COM & LPT" then shows up in DM with the new port on COM 17. Going in to the advanced settings and selecting the COM Port Number pull down, it shows COM3-COM16 as "in use", but these ports don't appear in DM.
I have several USB-serial adapters and other USB devices plugged into the back, but they don't show up in the DM.

I reset the PCIPnP to yes in the BIOS to no effect - still don't show up in DM. When I reinstalled drivers, the COM ports for the drivers, the numbering all started after COM16. If I go in and change a working COM port to COM3-COM16, it says they are already in use and can't open them.
