Midi port - Game port

I've got an external sound card with midi port installed. (Fortissimo II)
My motherboard is a MSI -K7N2G (Nforce2) card.

Everyting installs except the midi port. (exclamation sign)
"This device cannot find enough free resources that it can use. (Code 12)

If you want to use this device, you will need to disable one of the other devices on this system."
Resource settings: I/O range: 0201-0201
Input/Output Range: 0201-0201 not available

I've tried a differrent pci slot, a different sound cards, it doesn't help
How can I resolve this problem or how can I hook my midi piano on the computer.

thanks

Thanks for trying to help me.
I've already did disable the onboard sound chip in the bios. (and I don't have an onboard midi port)

I carefully examined the bios settings.
I already disabled everything i don't need (2 com ports)
In the windows hardware device manager I can't find any other resource setting that conflicts with the midi port or that uses the same settings. (view by resource)

I think that the problem starts with the motherboard. Perhaps the manufacturer decided to wipe any connection for a midi port.
So windows sees there is a midi port, he installs the software but don't know how to connect it.

Is there a way to solve this?
