PE	file: 0309_WheaSupport_95b18380d0d5 (from HR650X_3647_AJAX_BIOS)
Build	info:
This	DXE driver implements Windows Hardware Error Architecture (WHEA)
via	SMM communication at ReadyToBoot:
The	driver also allocates a shared communication buffer (0xE000 bytes)
at	0x4000 offset for HEST+ERST data, 0x6000 offset for BERT.
