## This mask is to control Heap Guard behavior.\r

- # requirement of UEFI spec, BIT7 is a try-best setting which cannot guarantee\r
- # that the returned pool is exactly adjacent to head guard page or tail guard\r

+ # Note:\r
+ # a) Heap Guard is for debug purpose and should not be enabled in product\r
+ # BIOS.\r

+ # requirement of UEFI spec, BIT7 is a try-best setting which cannot\r
+ # guarantee that the returned pool is exactly adjacent to head guard\r

+ # c) UEFI freed-memory guard and UEFI pool/page guard cannot be enabled\r
+ # at the same time.\r

# BIT0 - Enable UEFI page guard.<BR>\r
# BIT1 - Enable UEFI pool guard.<BR>\r
# BIT2 - Enable SMM page guard.<BR>\r

# BIT7 - The direction of Guard Page for Pool Guard.\r
