can't install multiple PCI-6534 cards on a Windows NT 4.0 machine

[pblase]

We're trying to install two PCI-6534 cards on a PC running Windows NT 4.0, under NIDAQ 6.91 (Labview 5.12). NI MAX shows the first card, but won't find the second one. We actually have 3 cards, and have tried various combinations and orders, but it will only find the first card in all cases.

Hello;

This is looking like an IRQ allocation issue.
Different vendors has different ways of allocating those IRQ to the PCI slots, depending on the BIOS used.

One suggestion is to upgrade the BIOS and try that out again.

Hope this helps.

Yep, that was it - thanks. the IRQ list was overloaded - we pulled a couple of non-essential things off of it, and the boards loaded fine.
