Detecting Usable Physical Memory

[onlyonemac]

There is a little misconception. There are no bugs that change the di register value after a call to the function. If you wanted to increment the di register, you would always have to do it manually. [...] The point is that some implementations assume the pointer is pointing to the same buffer all the time, e.g. manually incrementing it between calls to make a linear array of entries makes the pointer point to a new buffer every time and that is the problem for some BIOS implementations.

Changes promptly reverted. But I'm not going to do the buffer re-use thing.
