Got a new 2.4 ghz pent 4 to function as a Linux Terminal Server (LTSP - RH8). When I boot it, it claims to be running at 1.9 ghz. The setup (press delete while booting) screen that is supposed to allow me to set the CPU speed seems to be "locked" (won't allow any changes to that screen) and does not show the set CPU speed option. Any ideas.
