PCI 64-bit master



Hi,

I am writing driver for ethernet card. Its 64-bit PCI
master.
My PC(mother board) is also 64-bit. I want to map my
card in 64-bit
address space but It does not get mapped in 64-bit
address space.
It always gives 00 for bit 2 & 3 in memory base
register indicating
mapping in 32-bit address space.

How can I map my device in 64-bit address space ?

Thanks

Regards,
Tejendra
