PCIS-DASK Device Driver Configuration in Windows 98PCIS-DASK/98 provides a utility, PciUtil. This utility is used to modify the allocated buffer sizes of AI, AO, DI and DO. The allocated buffer sizes of AI, AO, DI, DO represent the sizes of contiguous Initially Allocated memory for continuous analog input, analog output, digital input, digital output respectively. Its unit is page KB, i.e. 1024 bytes. Device driver will try to allocate these sizes of memory at system startup time. The size of initially allocated memory is the maximum memory size that DMA or Interrupt transfer can be performed. It will induce an unexpected result in that DMA or Interrupt transfer performed exceeds the initially allocated size.
The PciUtil is installed with PCIS-DASK/98 and located in <InstallDir>\\Util directory.
The "Driver Configuration" window is shown as below.
