Yes it will. With /amd64, the address space is larger than 4 GB. With /i386, it is always limited to 4 GB, no matter if you use PAE or not. (Actually the address space for user processes is even more limited: 4 GB minus the kernel's address space.) Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co.
