The installation can se the total amount of ram, but can't use it - unless you compile the kernel with PAE option. Don't know about limits in fbsd5.x but I'm sure it's "fixed". > > I would avoid to tweak kernel parameters, if possible, like KVA > pages and similar things I don't know ;) > > Anyone with similar experiences could, please, remember me actual > limits ? I run production serveres fbsd4.10 with 4gb of ram and with PAE compiled into the kernel. P.S. don't cross-post a thread to several liste like you've done with this one. Stick to one and only one list. People are kind enough to point you to another list if you're on the wrong one. respectfully /per per@xterm.dk > > Many thanks in advance! > > > -- > > Alessandro de Manzano > > System & Network Administrator > Playstos - TIMA S.p.A. > Corso Sempione 63 > 20149 Milano, Italy > > tel.: +39-023314153 > fax : +39-02315678 > email: demanzano@playstos.com > > http://www.playstos.com > > _______________________________________________ > freebsd-hardware@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-hardware > To unsubscribe, send any mail to > "freebsd-hardware-unsubscribe@freebsd.org"
