Go to RapidDriver Main Page

The operating system allocates resources to the PnP PCI devices automatically, and you can evaluate these resources at corresponding tab pages. In additional, you can describe the DMA stuff, if your PCI device has bus-mastering capability. You should set all parameters at the Bus-Master DMA page based on your knowledge of device (RapidDriver Source Builder edition only!):
use bus-master DMA - check this box if your PCI device has bus-mastering capability.  
Name of DMA - used by RapidDriver Source Builder to create an AdapterObject.  
Max Length - maximum length of a single transfer, must be round up to a multiple of the memory page size (0x1000 for the Intel platform).  
scatter/gather support - check this box if your device supports scatter/gather list.  
allow 32-bit address - device can use 32-bit physical addresses.  
allow 64-bit address - device can use 64-bit physical addresses.
