You're using the 32-bit version, right? The design of x86 architecture (i.e. it's not FreeBSD's problem) is such that a part of memory addresses needs to be set aside for hardware uses, such as the PCI bus, AGP memory & others. This manifests as "holes" in memory that are not accessible to OS. There are two possible solutions: you may try compiling a 32-bit kernel with PAE (but not all drivers support PAE), or install the 64-bit version of FreeBSD. --------------enig343A95737B28C14A24E5A1A2 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.4 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFpWusldnAQVacBcgRAklWAKDmQ18OdqGb3Rb6+ZitXL5fSp+VfwCgj2ZR T6RfJobfc/fG7s/GaTxBdow= =Irmg -----END PGP SIGNATURE----- --------------enig343A95737B28C14A24E5A1A2--
