What is the "default value" then? Pentium? K5? 6x86? : It sounds like there could still be problems. : (Besides, we like jumpers! Especially when they fall off onto the : motherboard and down between some cards that then have to be removed to : get at it... :)) : P.S. If the CPU doesn't boot, then how can the BIOS (a ROM chip, the : code of which has to be executed by something) set a value in CMOS? Is : there an additional microcontroller onboard to do these tasks? Not a bad : idea, since a microcontroller may become std equipment when the I2O spec : starts to get implemented. Maybe that stupid turbo switch could be used to reset certain parameters like Clock multiplier, external clock frequency. Of course you would have to put a nice plastic cover on the switch (aircraft style). Actually this should be very simple and cheap to implement.
