memory and pageable page questions

[Drew Chen]

In the lecture
notes, it says
GeekOS has 8mb of
physical memory
When bochs loads, in
Init_Mem() it prints
"3072KB memory
detected, 387 pages
in freelist, 1048576
bytes in kernel
heap"

what does this mean?
is there 8mb or 3mb
of memory?
is there soem
separation in memory
that i dont
understand?

also can someone
clarify what do
parameters in
Alloc_Pageable_Page()
are?

If you look in the ~/project4/build/.bochsrc file, you can see that they
set the available memory to 3MB for this project - there's a comment
referring to paging.

I took this to mean that it doesn't matter how much memory there is and
have been working under the assumption that the amount of memory is
subject to change.
