Routine Description:

Create a Legacy Boot Event.

Tiano extended the CreateEvent Type enum to add a legacy boot event type.

This was bad as Tiano did not own the enum. In UEFI 2.0 CreateEventEx was
|
||||
added and now it's possible to not voilate the UEFI specification by
|
||||
declaring a GUID for the legacy boot event class. This library supports

the R8.5/EFI 1.10 form and R8.6/UEFI 2.0 form and allows common code to

work both ways.
