I've got a Lucky Star Slot 1 440BX motherboard and have bought a P2 266 Klamath to do some underclocking for DOS games - this board has it's multi and fsb clock settings in BIOS not switches/jumpers, making it ideal for this unlocked P2.
Browsing through the manual I saw something that stood out - TURBO66
"TURBO66 is an over-clocking jumper which enables 66 MHz CPU to run at 100 MHz. TURBO66 is only reserved for internal test only. No guarantee is provided for over-clock setup."
Should it be connected to a switch or momentary connection? Sadly the only AT case I have is baby-AT and won't take this sized board. Any reccomendations for 3.5" or 5.25" bays that have a turbo switch?
ideally if this thing can be switched while the pc is on, then i can quickly go between 250mhz (100 x 2.5)and 166mhz (66 x 2.5) without rebooting - perfect for any dos game that gets divide errors when running on CPUs at over 200mhz.
any other boards with this jumper? thoughts? does anyone have experience with this kind of jumper?
