On another note, I understand that with 24-bit addressing, you can address
up to 16MB of RAM (2^24 is about 16MB), but why is it only 128MB for 32-bits?
2^32 comes to about 2GB.  Am I to understand that as 32MB SIMMS come out, and
then 64MB SIMMS, etc., that the ultimate limit is actually 2GB?  Or is there
some other limitation that is keeping it at 128MB?
