Old modded 530s begging to be unlocked

Hi, anyone have a DL link and/or copy of an unlocked version of the old Dell 530s bios? This old thing's all I've got at the moment, (new computer being built and such) and it's been upgraded quite a bit when compared to it's original setup, but it's still got that [censored] hide-everything-overclock-related bios Anyone know how to unlock this thing?
