Hey Wim,
I am not sure what a magma-box is. I have searched all over google and I haven't been able to find one. This brings up my next question of how you are installing a PCI-6034E and PCI-6377 on the laptop. National Instruments driver does not support this and I am pretty sure the DMA on the devices wouldn't work as well. The main difference between the PCMCIA devices National Instruments sell and the PCI devices is the DMA channels. If you need to use a laptop I would recommend purchasing the DAQCards or DAQPads that can connect to USB, Firewire, or PCMCIA slots. These devices are supported on laptops. The PCI devices are designed to work on desktop computers with standard PCI busses that allow for DMA channels and ISA based interrupts.
I hope
this helps out.
