If you do nothing, all will be available.  To tell what is available,
run the "mem" command, and look for information in this order:

1. If it lists available expanded memory, that's how much go32 uses.

2. If it lists XMS memory, that's how much go32 uses.

3. If it lists extended memory, that's how much go32 uses.

Go32 will not use memory from more than one source, and searches for
the first available type from the list above.

Normally, when you run a memory-aware program (himem.sys, xms.sys,
emm386.sys), the default is to convert all memory, so unless you try
to do it wrong you usually won't.
