Hi all,

I'm trying to implement PCI Bus Mastering for my IDE device. Im able
to read the BAR address from the PCI configuration space. For
initialization of PRD table entry, it asks for some Physical address.
What value should be given for that? Any random physical address would
suffice? Also what address can be given for the PRD entry register?
All the above is for Kernel which we have developed.

Thanks in advance.
