With 32-bit pointers, you can only address 4GB,
so most of that 26GB won't help.
To find the amount of memory available use the command "ulimit -d".
The answer will be in KB.
The command "ulimit -H -d" will tell you the upper bound.
If the you are not at the upper bound,
the command "ulimit -d unlimited" would give you the maximum available.

After that, your only options are a smaller model or a larger address space.
Is there a 64-bit linux that will run on a Pentium?
