Or is this a 32-bit system WITHOUT extended memory support? |

|
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. |
