<pre wrap=""><!---->I think there are a couple of possible fixes depending on what the

If the problem is that it needs to be at a fixed address, allocate it
at the top (as high as you can before the IOAPIC) of the address
space, and mark it fixed.

It's basically really just a fixed address memory space of a certain
fixed size that needs to be kept free by the resource allocator, very
similar to the way it needs to be done for the IOAPIC and Local APIC.<br>
<br>
Since the PCIe BAR is part of the northbridge, I tried to tell the
resource allocator to do this in the northbridge.c code, but I couldn't
seem to figure out a way to make the (old) allocator honor it.<br>
