I also run i386 on two different boxes that have 4 GB RAM, and hw.physmem is set to 3.something automatically: olli@hexagon:~> sysctl hw.physmem; uname -rsm hw.physmem: 3474989056 FreeBSD 8.1-STABLE-20100908 i386 olli@atom:~> sysctl hw.physmem; uname -rsm hw.physmem: 3740434432 FreeBSD 8.1-PRERELEASE-20100620 i386 I haven't touched hw.physmem on these machines myself. Both boards have 2 x 2GB DIMMs. The former is an ASUS M4A88TD-V EVO/USB3, the latter is an ASRock A330GC. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b.
