Hi - is it possible to load a SMP version of a kernel on a system running a single CPU version of the kernel without a reboot? For instance, a quad CPU system was accidentally booted as 2.6.9-78.0.5.EL but we need to load 2.6.9-78.0.5.ELsmp instead. Any help would be appreciated. -- Article. VI. Clause 3 of the constitution of the United States states: "The Senators and Representatives before mentioned, and the Members of the several State Legislatures, and all executive and judicial Officers, both of the United States and of the several States, shall be bound by Oath or Affirmation, to support this Constitution; but no religious Test shall ever be required as a Qualification to any Office or public Trust under the United States."

And need a lot less work. -- Karanbir Singh CentOS Project { http://www.centos.org/ } irc: z00dax, #centos at irc.freenode.net
