32 Or is this a 32-bit system WITHOUT extended memory support?
33
34 I don't properly understand it, but with a 32-bit system the kernel uses
35 1GB of memory and user-space uses the other 3GB. Extended memory support
36 means each process can have its own 3GB space which enables you to use
37 all available memory, but without it I think the entire system is stuck
38 in the first 4GB.
