Little guide on how to show all the settings in clevo insyde_h20 uefi.

first things first

The operations in this guide will most likely unlock ALL settings in this bios. Do NOT do this if you don't have a good reason! If you think something is wrongly set and you are unsure, just go to load the optimal defaults, or your device may even can't power on! Note:some settings may not be reset with only loading optimal default, in this case you need to fully clean the nvram by removing the cmos battery. It's unsure what options have this problem but there sure are.

values

  • NH50/NHxxRA
    • offset is 0x133
    • value is 0x01
      • tested on hasee_z7m-ct5na(oem modded bios)
  • NHxxDPx
    • insyde/clevo hard disabled the show all option with a always false compare in their bios.
    • You need to unpack the setuputility from the bios then find the assembly and modify it to true and repack_flash the bios to enable the options.
      • tested on hasee_z8-cu5xx(mining edtion)
  • NH70RDQ
  • NHxxExQ
    • offset is 0x212
    • value is 0x01
      • tested by schnoog no Medion Erazer Crawler E25 - NH55EJQ - FW: NHxxExQ-M BIOS 1.07.05RME1

generic steps

  1. Download the modded "uefi shell" here https://github.com/datasone/grub-mod-setup_var ,and save it in a bootable device
  2. restart into uefi main menu(from windows advanced reboot or press f2 after power on),choose "Boot from file",then choose it.
  3. run "setup_var [offset]" "setup_var2 [offset]" "setup_var_3 [offset]",and find out which command can find a GUID that has a name of "Setup".(Just ignore the mismatch message and look for "Setup")
  4. run that command multiple times,and write down all the current values of the offset of all GUID.
  5. run "that_command [offset] [value]".If the command set the value on the right GUID,go ahead.If not,use the same command with values you previously saved to set them back.Try until you set in the right GUID and other GUID are still default.
  6. Run "quit""exit" or other to exit to the uefi main menu.
  7. Start the setup utility,and see if the magic happens.

well

Please improve this if you find such values on other models。And sorry for my bad english,any contribution is welcome！

something went wrong,what to do?

If you can still power on the laptop,try the following.

  1. Fully poweroff the laptop,if you can not even boot,hold the power button for about 5 secs to force poweroff.
  2. Hold Fn + D,then press power button,your laptop should start then immediately power off,release the keys.
  3. Laptop should auto power on again,and the settings are restored to default,you can mess with them again.
