Verification method: setup_var scripts on multiple Acer Swift 3 and Lenovo Yoga units running Rev 35 successfully toggled these variables, confirming their presence.
: Allocates system RAM to be used as VRAM for your integrated graphics. Increasing this from 32MB to 64MB or 128MB can resolve stuttering in low-end gaming and video playback. 3. Overclocking & Performance (Formset)
The is a common UEFI firmware found on many Acer, HP, and Lenovo laptops. While the standard interface often restricts users to basic boot and security settings, a hidden "Advanced" menu exists that allows for deeper system tuning, such as adjusting VRAM, CPU power states, and fan control. Verified Methods to Unlock Advanced Options
A complete GRUB binary with setup_var functionality is available on GitHub for this purpose. insydeh20 setup utility rev 35 advanced options verified
Power users and enthusiasts often seek to unlock these hidden options. Accessing the advanced menu allows modifications to several restricted parameters:
specifically indicates a certain era of design. It is functional but often restricts access to low-level hardware settings to prevent novice users from damaging their systems. Why Access the Advanced Options?
The utility organizes settings into several standard tabs: , Main , Advanced , Security , Boot , and Exit . From these menus, users can configure system time and date, manage boot device priority, set passwords, and—under normal circumstances—adjust a limited set of advanced parameters.

Disabled (Fan only runs when hot) to reduce noise. Enabled for better cooling during gaming. 5. USB Legacy Support / USB 3.0 Configuration
Turn on the computer and immediately press (or Fn + F2 ) repeatedly to enter the standard InsydeH2O utility.
The transition from legacy BIOS to UEFI (Unified Extensible Firmware Interface) brought enhanced security, faster boot times, and more granular hardware control. Insyde Software’s InsydeH20 is one of the “big three” UEFI firmware solutions (alongside AMI and Phoenix). Revision 35 is widely deployed in Intel 6th to 10th generation Core platforms (Skylake through Comet Lake) and corresponding AMD Ryzen mobile series. Instead of modifying the interface itself
