There is such a thing as I/O mapping, which decreases the amount of
usable RAM. Usually the memory is mapped to just below 4GB.
AGP GART is there for example (256MB usually), as well as other things
(PCI for example).
Thus, you usually see 3.3 up to 3.5GB of RAM.

Hi everyone,
Further to my last message, I tried a memory dump
in 16 bit real mode running himem.exe and emm386 and found a great improvement
compared to 32-bit protected mode using CWSDPMI (or DPMIONE which was even
worse). A total of 3.24 GB of extended RAM is detected - here is the
