Changing I/O ports & IRQ's

I'm using RH6.1. I have a serial mouse and a Comtrol RocketModemII PCI multimodem card. The two conflict from time to time. I'm guessing they're conflicting either through I/O ports, but most likely interrupts. I've checked the /var/log/messages and when this happens it continously says: Interrupted system call. Where do I need to look to eliminate this problem?

The problem can be fixed with setserial. Follow the instructions in             /usr/doc/setserial*/ to have the serial ports reconfigured

Look at /proc/interrupts, /proc/ioports to find out where the problem resides. Further look at your BIOS. Try making the BIOS leave the mouse's interrupt alone when it is handing out PnP interrupts.

I went into the BIOS and set the serial port to AUTO instead of a fixed address. This fixed the problem. I'm guessing Linux was assigning the mouse's fixed io address to the modem, but the mouse still had precedence since it had its address assigned in the BIOS.
Thank you both
