Why can't it see 4 gigs without PAE? You only have 4g physical address space without PAE and your board takes 1.5G for memory mapping and such, so you only have 2.5G for RAM. Most boards just claim 0.5G, but 1.5G is not that unusual. Either use PAE, install amd64 if your CPU is 64bit capable or live with just 2.5G. There is no other option, since this is a hardware limitation. -- B.Walter http://www.bwct.de http://www.fizon.de bernd@bwct.de info@bwct.de support@fizon.de
