Does that mean that if I put in like 4 gigabytes of ram like half of it gets reserved?
Usually no, but it depends on the chipset.

Or does the bios somehow remap the memory so that I can access everything?
Usually yes, but it depends on the chipset.

If so, does it actually map above 4 gigabytes?
When the chipset is capable of remapping memory, yes.

How does one even access that memory in 32 bit mode?
PAE.

Or does some part of the RAM become unreachable?
Usually no, but it depends on the chipset.

Also, can I manually remap it?
You should let the firmware handle it.
