// [Category]  	Bug Fix
// [Symptom]  	AHCI legacy support module is corrupting the memory.
// [RootCause]  	AHCI legacy support module is corrupting the memory as it
// was using wrong offset for storing the base address.
// [Solution]  	Properly calculating offset for storing the base address.

// [TAG]  		EIP76393
// [Category]  	Bug Fix
// [Severity]  	Important
// [Symptom]  	Any time AHCI is starting when EBDA size is more than 64K,
// the problem will show as memory corruption.
// [RootCause]  	AHCI INT13 code does not use EBDA properly when at the
// time of EBDA allocation current size of EBDA exceeds 64K
// [Solution]  	Modified code to extend the width of EbdaStart offset from
// 16-bit to 32-bit.
