Hello. I have a computer with an ATC-1000+ AT motherboard. Its front panel connector has a turbo LED connection, but I cannot find any place to plug the turbo button in.
When I turn the computer on, the turbo LED is on by default. Does that mean that my CPU is stuck on 4.77MHz or 8MHz speed? It shows 200MHz on the boot screen.
When I press Ctrl,Alt,+ or Ctrl,Alt,- the state of the turbo LED does not change.

http://th99.classic-computing.de/src/m/A-B/34084.htm - Some ATC-1000+ specifications and jumper settings. May be useful.

DOS PC - MS-DOS 6.22
ATC-1000+ (BIOS v1.3 04) - Q1 missing - ext.3.3V on JP6 pin 2
Pentium MMX 200MHz 2.8Vcore 3.3Vio
Matrox Mystique 220, Voodoo 2, Sound Blaster 16 (CT2230)

Usually by the Pentium era many boards dropped turbo functionality as it wasn't needed anymore. There might be a keyboard shortcut but I don't know it.
