Juan,
I was just checking my notes on how I installed it on a PC earlier. The PC I had was a Dell Optiplex GX110. I did have a few problems with the optimization floppy disk myself, so I made notes on how I got it to work.
1) If you already have the optimization software installed, remove it from the PC, but leave the PCI MXI-3 card in the machine.
2) Power up the PC. Shutdown the PC.
3) Reinstall the MXI-3 optimizatin software. The software does run, but mine didn't work the first time.
4) Restart the PC. My software then found the MXI-3 card with no problems. I did NOT mess with any BIOS settings at all. My PC had no other PCI cards in the host PC, but it did have a built-in E-net network card we use to connect to the
plantwide LAN.
That was it. Ironically, we had PCI DAQ cards in the PCI extension, and even when the optimization was not working, I could "see" the boards in NI-MAX (don't know if you're using that).
Let me know if that doesn't work.
