I have tried to install both x86 and x86_64 DVD on 3 difference systems, only one of them can install FC4 sucessfully, all others show kernel panic right after booting from DVD rom. FC4 test 3 doesn't have the same sympton. Here are the systems that I tried: System 1 ======== CPU: Intel Pentium 4 640 (3.2G with EM64T) M/B: ASUS P5GDC-V Delux (Intel 915G + ICH6R chipset) IDE DVD-ROM SATA Hard Drive FC4 x86_64 (can not install) md: autorun ... md: ... autorun DONE.
