This method for accessing the advanced settings in Insydeh20 Bios is tested on an AMD-based Acer Aspire V5-552PG, and is assumed to work on other computers like Lenovo and HP with Insydeh20 Bios:

1: Press On/Off for turning the computer on
2: Immediately pres [Fn] and [Tab] simultaneously for three (3) times before the Acer Logo appears.
3: Press [F2] simultaneously for entering the Bios setup menu.

Alternative:
1: Press On/Off for turning the computer on
2: Press [F2] simultaneously for entering the Bios setup menu.
3: In Bios setup menu pres [Fn] and [Tab] simultaneously for three (3) times and then [F10] for exit and save changes.
4: While rebooting, Press [F2] simultaneously for entering the Bios setup menu.

Now at least two new menu options are available in the Bios main menu. Further options in sub-menus may very between computer brands (and installed hardware).

In systems where Bios is entered via pressing [Esc]-key, you can enable the advanced settings by clicking [Esc] once and then press [a] + [F10] simultaneously (this is a feature that I have not tested).
