- Only check the RAM from 0 - 640 KB and 768 KB - 1 MB now. That's available on all boards, regardless of what DIMMs you use. Tested on the Tyan S1846, works fine. - Properly set the PAM registers to allow the region from 768 KB - 1 MB to be used as normal RAM (required for the above). - Document all of this properly. Add/improve other documentation, too. - Simplify and document code in northbridge.c. - Cosmetics and coding style.
