Hi, I have an Intel Desktop Boarrd D915GEV with 4 GB DDR2 RAM on board and Pentium 4 530J 3.0 GHz. I was insatalling Red Hat Enterprise WS V3.0 Update 4. The OS only found 3GB RAM. Is this the limitation of IA32 for 3GB RAM or am I missing something? Please help! Thanks -- Wen wentline at gmail.com
