There is a SERIOUS bug in all pentium CPUs. The following code will crash any machine running on a pentium CPU, MMX or no MMX, any speed, regardless of OS (crash as in instant seize, hard reboot the only cure): char x [5] = { 0xf0, 0x0f, 0xc7, 0xc8 }; main () { void (*f)() = x; f(); } This require no special permissions to run, it works fine with average-joe-userspace permissions. I have verified this, it works. Demand a new CPU from Intel. ----------------------------------- visit my web site: www.pes.edu/~shyams/ ----------------------------------------------------------------------- LIH is all for free speech.
