Hi Sushma,
It’s depend on the platform BIOS to decide which option rom needs to be

Hi Stephen,
Get the MemoryMap using GetMemoryMap function calls and run the memory test
, where the memory type belongs to "EfiConventionalMemory" type. Other memory
type regions are used for the different purpose. Please check EFI_MEMORY_TYPE
and table 25 in the UEFI Spec.

Hello Michael,
CloseEvent is enough to kill the event notification and it's right method to
do it. After CloseEvent called, the event will not be triggered when the

For DOS environment, you need another driver that would take care of the
