However, my problem is ... deferred as I will simply use 3GP of physical memory ... my mainboard or bios does not seem to support PAE. -- Laptop nc8430, 4GB Ram and fglrx https://bugs.launchpad.net/bugs/141439 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
