I recently have built my computer system and everything seems to work fine except for the speed changes on the system. The turbo button and MHz display on the midtower case work fine. WHen pressed, the turbo light lights up and the 33 comes on the display. Depressed the 8 shows up without the turbo light, but the system doesnt seem to really care. I have heard that the AMI (Mark II) motherboards may not work with the turbo buttons. If thats the case, is there anything I could do to get it to work with it? But aside from that, ctrl alt -/+ doesn't even work! The turbo button is one thing, but it doesnt accept the keyboard command? Reset by switch and keyboard work fine, but it just doesnt like turbo. I was told that it could possibly be a jumper or some sort that is keeping it in high gear. I can't seem to find this addressed in my motherboard manual. (The case manual is worse, a flimsly piece of paper with non-understandable figures). Any help on this matter is appreciated! I will give summaries on request or post if there is demand.

As far as I know, my AMI Mark II motherboard does not support a TURBO
switch. The only way to change speeds is through the keyboard. There
is a connection from the board to support a display device, which I used
to connect to the turbo led and display on my case. It sounds like your
turbo switch and light are connected together and not to a remote line.
In my situation, I had to make numerous adjustments before I got the
display and polarity of the various wires to match the motherboard. My
turbo switch operates independently of the display - needless to say, it
sits there doing little except allow me to fiddle.
