Hi All, You better ask this as, What process can not do in ring 0??? Process can do anything, like God. You can refer Intel's IA-32 architecutre manuals to get more info about this. http://www.intel.com/design/pentiumii/manuals/243190.htm Tharindu
Tharindu, Your 6 months out of date. AIUI, Ring 0 now has 2 sub-modes. The fully priveledged mode you imply is used for tradional operating systems and for the host os in a virtual machine (vm) setup. The new restricted ring 0 sub-mode is designed for guest os'es in a vm setup. -- Greg Freemyer The Norcross Group Forensics for the 21st Century -- Kernelnewbies: Help each other learn about the Linux kernel.
