(Hasn't this same question appeared here before?)

You have 4 Mb of memory, but most likely 640k of DOS (Conventional) memory.
This is the memory which GlobalCompact() works with, thus the 280k being
returned is most likely correct.  Remember, DOS, device drivers, TSRs, and
Windows itself are all sharing this memory.  If you want to paint a more
global picture of your memory resources you will have to make some EMS
calls to determine how many free/total pages are available.
