Sure you can use PAE on i386 but it is really a workaround. Now there are about 10% of the ports out there that will not run on AMD64 with the most important "everyday" one being the nvidia driver for xorg (note though contrary to the man page nv does support the max resolution of your card/monitor [well almost I ca get 1400x1050 but not 1600x1050 on my 8400GS and 21" wide screen]). > > > > >> On Mon, Mar 24, 2008 at 4:35 PM, Ivan Voras wrote: >> >> >>> Irodatechnika Hajdu wrote: >>> >>>> Hi! >>>> >>>> I have got a XEON (E5320) based computer.
