2 | This file declares the Device Recovery Module PPI.\r | |
3 | \r | |
4 | The interface of this PPI does the following:\r | |
5 | - Reports the number of recovery DXE capsules that exist on the associated device(s)\r | |
6 | - Finds the requested firmware binary capsule\r | |
7 | - Loads that capsule into memory\r | |
8 | \r | |
9 | A device can be either a group of devices, such as a block device, or an individual device.\r | |
10 | The module determines the internal search order, with capsule number 1 as the highest load\r | |
11 | priority and number N as the lowest priority.\r | |
