Hi,

I run Linux on VirtualBox.
The opportunity for me to get knowledge about ACPI Tables.

And in particular, the MCFG Table.

Here is what I obtain :

But, I'm deconcerted by entry->baseAddr == 0

it should be a valid address to a PCI Enhanced Configuration Area, no ?

Thanks for yours answers

I don't know what you see in that picture. All I get is a "wrong way" sign.

But yes, base address should be nonzero.
