CPU testing utilities in optimized assembler for maximum loading P6 (Intel Pentium Pro/II/III and Celeron TM), AMD K6, AMD K7 (Athlon / Duron / Thunderbird TM) and Intel P5 Pentium chips.

They have been optimized for different processors. FPU and ALU instructions are coded an assembler endless loop. They do not test every instruction.

The goal has been to maximize heat production from the CPU, putting stress on the CPU itself, cooling system, motherboard (especially voltage regulators) and power supply (likely cause of burnBX/MMX errors):
· P5 is optimized for Intel Pentium w&w/o MMX processors
· P6 is for Intel PentiumPro, PentiumII&III and Celeron CPUs
· K6 is for AMD K6 processors
· K7 is for AMD Athlon/Duron processors
· MMX is to test cache/memory interfaces on all CPUs with MMX
· BX is an alternate cache/memory test for Intel CPUs

burn* will run endlessly _UNLESS_ an arithmetic error is detected. Check up on it with the Task Manager. It will terminate with an error code of 1 if a computational error is detected. It checks every 3-8 seconds. I haven't seen any terminations, the CPUs always lockup first. Let me know if errors happen to you.
