Addresses

I was working with directx and its diagnostic features the other day directx
8.1 that is and came across a bunch of hex numbers and devices attached at
those numbers motherboard services, IO, &c. Are these adresses virtual
addresses for the kernel or actual physical adresses?

directx

I'm not sure what is that you talking about. I don't see anything like that
in the DX diagnostics tool. But if you're refering to 'resources' tab in
properties for a device in the device manager those addresses are physical.
Also virtual address for the kernel is always greater then 0x80000000 while
physical address are much smaller :-)

That is not true. The kernel/user memory address boundary can vary by using
the 3GB switch.

Sure. But that's not gonna make them any smaller :-) Nice catch anyway.
Thanks.
