ACA1221LC how to reset it if overclocking jamms it?

[PDrill]

I would like to test out if it works @ 40Mhz (just a checkbox in Acatool) but how can I get it back to original state (26.67) if it doesn't work at all after overclocking?

The ACA1221lc comes with the jumper in "park" position. The presence of these jumpers is a leftover from the predecessor card ACA1221ec. All features of the card are controlled with the ACAtool (see further down). Only in emergency cases, you will need to set the jumper to "unprotect", which will let the card start in a safe configuration without overclocking, a low amount of memory and IDE speeder disabled. You will only need this jumper setting if you have saved a configuration that permanently keeps the computer from starting.

Acatool allows you to get / set the speed without saving. You can test it for a long time, then once you're satisfied you have found a stable speed setting, you can save.

Oh rite then, thanks. Didn't even think it would work just by clicking the boxes without saving. Well, not very stable @ 40Mhz but doesn't matter.
