I need for Acer A0756 with HM70 chipset BIOS to be unlocked. I am not one who usually will do something so extreme but I need at these features to disable and to enable the Sata HD. I want to boot from USB without interference from the Sata drive. I am not sure but I believe this is my only true way to get over this problem other than opening up the netbook and disconnecting the HD. If someone can help or has a better solution I am willing learn. Here is the link to the latest BIOS for my Acer netbook as of today. Thank you far any help you can offer!
