Device cannot find any free I/O resources (code 12)

I have a older IBM pc 340 windows 98se into which I tried to put a 2.0 USB pci card......I could not get the card to work although it apparently installed correctly as it was listed in the device manager with no exclamation marks or indicators.  However, while installing the usb card, the IRQ's for the modem, and video display adapter has apparently been changed.....  I have removed the usb pci card and am now in the process of trying to get the video adapter and the modem to work properly again.  I have removed these items on numerous occasions.....tried reinstalling them... all to no avail.   I have physically removed the modem and am now attempting to install just the video adapter.  I continue to receive the error message that "this device cannot find any free input/output range (I/O) resources to use (code 12).

I have attempted to solve this problem by going to some of the previous solutions that are offered here on EE.  I have noticed by using that info that when I go to the device manager under PCI bus properties it tells me that IRQ steering is disabled.  I have not been able to enable IRQ steering.... If I understand things correctly....this appears to be the problem.   How can I enable IRQ steering....if that is the problem?    I have changed BIOS settings....I think I have them back to where they were....but maybe not......I have myself in a mess right now......can anyone give me a step by step walk thru on how to get this thing back on line.......the machine belongs to a friend and he is gonna be PO'd.....its an old piece of crap...but he doesnt think so.......help.

ok got it, at least I think I do......I went back into the bios and shifted some settings on chnls avail for IRQ.....modem and video card have loaded properly and are apparently working.......if anyone has a good site to go to that will teach me more about the IRQ and how things like that work....I will still award the points for that information.
I too recall fond memories of try to get devices to work when I used W/98. W/XP seems to handle these things a little better. My best solution was to try installing the pci cards into different slots. After spending several hours playing musical chairs with the cards, I would eventually find a combination that would actually work. I don't know of any definitive sites that are much help about how IRQ assignments work. Microsoft have written a few articles: http://support.microsoft.com/default.aspx?scid=kb;en-us;182604 http://support.microsoft.com/default.aspx?scid=kb;en-us;182628 etc. In the past I've searched for solutions for an explicit problem, but the swapping cards around solution was invariably the best solution.

However, you don't have to award the points to anybody. You can request a refund on the basis that you've solved the question yourself. http://www.experts-exchange.com/help.jsp#hi9
