Perhaps you can be a bit more specific.
The system in fact has a 512MB chip and a 256MB chip for a total of 768/775Mb

You seem to show that this is shown in BIOS as a single entry, rather
than an entry for each stick, is that true?

And of course, I dont understand how to interpret the numbers that I see.
My first guess would be that they are starting point, size (is there any
documentation?,- I didnt find it)

But if I believe that, then 0x2fffc000 = 805289984 which is wrong for the size.

So, back to my initial question: How do I interpret this stuff?
