The Initialization of UEFI

In this blog, I will show you three points of the UEFI:

a.     The process of initializing the UEFI.

b.     The components of DXE.

c.       The bridge between PEI and DXE – HOBS.

 To make it more intelligible, I will introduce them as the flow charts.

1. The process of initializing the UEFI
 

2. The components of DXE

 EFI System Table, Architecture Protocols, DXEFoundation, Drivers. And the relationships of them are as follows:

3. The bridge between PEI and DXE - HOBS

HOBs (Hand-offBlocks): they are series of data structures in memory. They are created duringPEI and read only in DXE.
