Consider the CMOS reset procedure. On a standard motherboard, a manual will show jumper pins or a button. On the AAHD3-VC, the manual cryptically instructs you to “short pins 7 and 9 on the JCMOS1 header” without even providing a clear header map in some versions. This is not a bug; it’s a feature of the ecosystem. Acer’s exclusivity here is structural: the manual exists less to empower the user than to limit liability. It says, in effect: “You may look, but only we truly know.”
