Allocating more than 64 DMA registers for NDIS miniport drivers

I’m developing an NDIS 5.2 driver for windows server 2003 64 bits.

In the documnentation of NdisMAllocateMapRegisters I see that:
“NDIS imposes a limit of 64 map registers per miniport driver”.

Is there a way to tell windows to increase the number of registers that my NIC has?

Is it possiable that this limitation decreases the maximum BW that I can get?

Thanks
