Host Interface Service
The Intel® DAL Host Interface Service (Intel® DAL HIS) is part of the Intel DAL infrastructure and serves as an intermediate layer between host applications and the Intel DAL firmware component:
- The Intel® DAL HIS serves as the communications channel between trusted applications and host-based applications.
- The Intel DAL HIS maintains the virtual model and state of the Intel DAL firmware subsystem. Among its roles is to ensure loaded trusted applications remain loaded after a firmware or machine reset.
Note
: While the component's official name is Intel® DAL Host Interface Service (Intel® DAL HIS), it is commonly referred to by its engineering name: JHI.See How to Create Your First Project for a C++ implementation example, as well as a C# implementation under "Create a .NET* Host Application".
