1. BIOS Settings

First of all, we recommend to update your BIOS to the latest version.

• Enter BIOS. The method varies for different motherboards, and Google is always at your service about this.
• Disable Secure Boot. Go to Security -> Secure Boot, set it to Disabled.
• Enable SGX Extension. Go to Security -> SGX (This name may vary according to the different manufacturers), set it to Enabled.
• If you can only find SGX: Software Controlled option, you will have to run sgx-software-enable in Ubuntu. You can download and execute it with the following commands:

wget https://github.com/Phala-Network/sgx-tools/releases/download/0.1/sgx_enable
chmod +x sgx_enable
sudo ./sgx_enable

• Use UEFI Boot. Go to Boot -> Boot Mode, and make sure it was set to UEFI.
• Save and reboot.
• You also need to make sure that Ubuntu is installed in UEFI mode. SGX is not guaranteed to work properly on the OS installed in legacy mode. In such case you may want to reinstall the system.

2. Install

mkdir phala
cd phala
wget https://codeload.github.com/Phala-Network/solo-mining-scripts/zip/main
unzip main
cd solo-mining-scripts-main
sudo chmod +x *.sh
sudo ./install.sh en

Check the SGX capability:

sudo phala sgx-test

Please pay attention to the following checks:

• SGX system software → Able to launch enclaves → Production Mode
• Flexible launch control → Able to launch production mode enclave

The report below would be a positive result:
