In two test systems delivered to a customer, NI-DAQ “forgets” which NI cards that are installed. It could work fine for several days, and then suddenly they are “gone”. Only way to find them again is to remove the NI cards, reboot without the cards, power off, then install the cards again and reboot.. The OS is Windows XP, NI-DAQ 7.4, cards: PCI-6602, PCI-6023E, and PCI-CAN.
The same customer has several identical systems that are working fine. One of the things they could find to be different is that the computers that “forgets” has IRQ’s up to 22, while the older PC’s only goes to 15.
Does anyone know why this happen, and if there’s a fix for the problem?
