How can I use PCI-6509 and PCI-6251 with Labview 6.1?

[MSARIKOC]

I bought PCI-6509 and M-Series PCI-6251 with the suggestion of your website instead of PCI-DIO96 and PCI-6052E.
Now now I see that I am not able to use them with Labview 6.1 and Traditional NI-DAQ drivers. Even I can't install the drivers of PCI-6251 into my Windows98 operating system. Is there any way to use them with Labview 6.1 and Windows98, or do I need to upgrade my Labview and operating system in order to use these DAQ boards.

Thank you.

indeed, you need to upgrade to the current version of LabView 7.1.1.
PCI-6509 and PCI-6251 requires DaqMx that can run only with LV version 7.X and higher. LV 6.1 requires traditional Daq.
Meries requires NIdaq 7.3, which cannot be installed on win 98 systems.
There is no work around
