This is the low level device driver used by all NI hardware device
drivers. PAL stands most probably for Platform Abstraction Layer and
what that means it is providing an uniform device driver API for
managing memory, IO addresses, DMA channels and Interrupts. Most
probably this NIPAL device driver API is almost the same on all
platforms NI develops modern hardware drivers for. This allows easier
porting of device drivers to new hardware as the big work for porting a
hardware driver is about porting this NIPAL device driver.
I
would not think that disk writing is the real culprit here, but it may
trigger a problem occuring earlier during VXI access.
