The best place to get help with your PCChips M571 (which version?), is on this Forum called 'the PCChips Lottery'http://www.stud.fernuni-hagen....142-...ums.cgi?forum=3
For starters, you can run that K6-2 500 with the M571 jumpered at 2.0x (which the CPU will 'translate' to mean 6.0x), and 75 MHz for the FSB.
This will give you 450 MHz, (not perfect, but a very good start), and if you ask at that other Forum, they'll tell you how to get 500 MHz out of it.
