IRQ Conflicts When Using Eagle Technology PCI-763C Reed Relay Boards with NI PCI-GPIB Hardware: GPIB
Problem: My Eagle Technology PCI-763C Reed Relay board is assigned IRQ level 9, which is the same as the NI PCI-GPIB boards. This is causing an IRQ conflict. Measurement & Automation Explorer (MAX) will not open and hangs on the splash screen. What can I do to fix this? Solution: Some Eagle Technology boards, the PCI-763C Reed Relay in this case, cause an IRQ conflict with National Instruments GPIB boards. When the Eagle board is removed from the computer, the NI boards begin to function properly again. In this case the Eagle PCI-763C and PCI-GPIB card were assigned the same IRQ level of 9. Other symptoms are that MAX will not open. The MAX screen will pop up but will hang there indefinitely. You can try moving the cards to different PCI slots. This works in some cases. If this does not work it may be necessary to try and manually set the IRQ levels upon booting by entering the BIOS with an <F2>, <F12> or <DEL> keypress during bootup.
