System will not recognize ATM card

I am new to the field of computers so please be kind. My company recently purchase from Dell the above system with 2 PIV, 2k RAM, 70GB hard drive, a Perc3/D PowerEdge Expandable Raid Controller, onboard 3Com Etherlink, Fire GL-2 AGP, all running on Windows NT. I removed the Fire GL-2 and replaced it with a Matrox g550 dual monitor card. I loaded NT 4.0 SP6a, Web peer-to-peer, Gov SW, and some GIS SW. I installed the ForeRunner Card.

This system will not recognize the ATM card. At initial startup, I get a plug-n-play error. Then, before going...

into the OS, the system stops and I get a F1 to continue or F2 to enter setup message. I have loaded the ATM drivers to no avail. I do not have the capability to actually place on a Lane. In addition, I have placed this card in one other Dell machine and the system booted fine. I have talked with Marconi; they think it may be an IRQ conflict. But if the system cannot see it, I cannot set an IRQ! Do you have any suggestions? Thanks.

It is most definitely an IRQ conflict. I'd remove every expansion card from the system that you can (i.e. only have the video card installed), then add in the ATM card. At that point, there should be no conflicts and it should recognize it. Then you can add back in one card at a time. If a conflict re-occurs, you may need to switch cards or set CMOS IRQ definitions.
