HELP !!! - MF1000a sound card

I use Open Linux 2.2.5 from Caldera.
I'm trying to setup my sound card (MF1000a Avance Logic) like this:

# insmod soundcore
# insmod soundlow
# insmod sound
# insmod uart401
# insmod sb io=0x220 irq=5 dma=1

...and see the message "Device or resource is busy"

What's wrong? Please help me.
Thanks.
Dmitriy Netchitailo.
