I am having a serial port conflict. My PC has one serial port on motherboard and a second serial port was added with a cable connected to the MB and uses a PCI slot. The second serial was disabled in bios. I enabled it and got a * next to serial port B saying select device in conflict with another device. . Everytime I boot up I am getting ERROR Com B configuration changed. Press F1 to resume F2 to Setup. Here is what my bios settings look like:
Serial port A enabled
Base I/O address 03f8
IRQ4
*Serial port B enabled
mode normal
Base I/O address 02f8
IRQ 3
In Control panel my IRQ setting look like this (There is no yellow ! point though)
IRQ3 Com 2
IRQ4 Com1 and 3
Ports
Com1 I/O 03F8-03FF
Com2 I/O 02F8-02FF
Com3 I/O 03E8-03FF
Any thoughts? I tried to change the IRQ in control panels by unchecking use automatic settings and clicked change setting, but it says This resource cannot be modified.
