What is the difference between umb and upper? How do you set their sizes respectively?

What exactly does himem do? Does it only take effect when it runs before emm386, or after it?

UMB memory is just Upper memory!

HIMEM.SYS must be loaded before EMM386.EXE.

HIMEM.SYS provides EMM386.EXE with the ability to manage memory beyond conventional memory!
