To: freebsd-questions@freebsd.org Subject: 3,5 GB Limit with x86 architecture Message-ID: <20020702123254.H9809-100000@klima.physik.uni-mainz.de> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Dear Sirs. I read a lot about a physical, x86 architecture dependend limit of 3,5 GBytes of RAM within a normal 32 Bit environment. Windows, 2k and XP, is not capable to address the upper 512 MB of memory if the system is equippted with 4GB RAM, due to the fact this memory area is reserved for the PCI mapping area. The question is only for my information. Does FreeBSD has a kind of workaround or is this limit really 'hardwired'? Thanks ... Oliver -- MfG O.
