I thought 32-bit operating systems had a hardm limit of 4GB of RAM, no? (Something to do with 2^32 being roughly 10^9, but I frankly don't know the details.)

- julian37 16y ago32-bit operating systems do have a hard limit of 4GB of RAM but that's per process. See PAE: http://en.wikipedia.org/wiki/Physical_Address_Extension http://en.wikipedia.org/wiki/Physical_Address_Extension
