1 | /** @file\r |
2 | GUID definition for the Linux Initrd media device path\r | |
3 | \r | |
4 | Linux distro boot generally relies on an initial ramdisk (initrd) which is\r | |
5 | provided by the loader, and which contains additional kernel modules (for\r | |
6 | storage and network, for instance), and the initial user space startup code,\r | |
7 | i.e., the code which brings up the user space side of the entire OS.\r | |
8 | \r | |
9 | In order to provide a standard method to locate this initrd, the GUID defined\r | |
10 | in this file is used to describe the device path for a LoadFile2 Protocol\r | |
11 | instance that is responsible for loading the initrd file.\r | |
12 | \r | |
13 | The kernel EFI Stub will locate and use this instance to load the initrd,\r | |
14 | therefore the firmware/loader should install an instance of this to load the\r | |
15 | relevant initrd.\r | |
