NIMAX 4.6.2, with NI-DAQ 7.4.4 legacy and AT-AO-10, first IRQ not recognized

[tpmjones]

Why doesn't NIMAX 4.6.2, with NI-DAQ 7.4.4 legacy, recognize the first IRQ on an AT-AO-10 when I have two IRQs configured?  It only recognizes the device when a single IRQ is configured.  Will this affect the operation of the board?  I have tried different IRQs, different combinations of multiple IRQs, reserving the IRQs for legacy ISA in the BIOS, etc.  The only thing that I can do to get the board recognized is set it to a single IRQ, even though the default is two IRQs and a DMA.

I am converting a system from Windows 2000 to Windows XP.  The original system had 3.02, with NI-DAQ 7.1 and there were no problems.  The board is ok.

Also, I am in a new computer, with a higher end processor and board.  everything in Windows seems to indicate there is no problem, it is only when I am in MAX that any problem is indicated.

Again, I don't mind using a single IRQ, I am not doing anything too intensive and the processor is much better with more memory, etc, so I don't think I'll be adversely affected.  I am just looking for an explanation and reassurance.

Ok, so it appears that buffered outputs require the second IRQ?  I tried to generate a SINE wave from MAX and got error code -10452, when using Channels 8 or 9.

grrrrr.....

what a waste of time and money.  There was no indication in any links to the device that it was not supported in XP.  Consider this closed.

Sorry that was so hard to find, but at least we have an answer.  I'll try to add some keywords to that article to make it easier to find in the future.
