I have a problem with Windows 2000 automatically assigning IRQs to some of my devices. In the screenshot provided, you'll see several devices all assigned to IRQ 9. I would like to change the assignment but Windows 2000 will not let me. I thus thought about going into the system BIOS menu and changing the settings. Dell 4100 system. It has been a long time since i've looked but as I recall there was an option in my BIOS where it said something like PnP OS? Yes/No.

If i set that option to No, then will I be able to manually re-assign them or not? Will it totally screw up my system? If IRQ 10 and 11 are supposed to be available, then why aren't they being used?????

I have been having a long-time modem issue with my setup and am just absolutely at my wits end trying to figure out what is wrong. Right now i suspect that is because it is on IRQ 9 (in the screenshot provided) and I know that internal modems are typically assigned to IRQ 3. Regardless, it's supposed to be IRQ 3 or 4 as dictated by the order of assignments on COM ports.

I have a winmodem (Dell provided) that connects ok upon boot up but if i get knocked off or disconnect, then it refused to re-connect. Always gives me some excuse about line being busy or password is not valid, etc. I have even tried new access numbers provided by my ISP (MSN). So I have to warm boot the system in order for the modem to connect again on the first try. My question is the paragraph in italics. And yes I have updated my drivers for the modem.

I would appreciate any suggestions.
