+  - Get EFI SMBIOS data structures, convert them to a traditional format, and copy to
+    Compatibility16.
+  - Get a pointer to ACPI data structures and copy the Compatibility16 RSD PTR to F0000 block.
+  - Find the traditional SMI handler from a firmware volume and register the traditional SMI
+    handler with the EFI SMI handler.
+  - Build onboard IDE information and pass this information to the Compatibility16 code.
+  - Make sure all PCI Interrupt Line registers are programmed to match 8259.
+  - Reconfigure SIO devices from EFI mode (polled) into traditional mode (interrupt driven).
+  - Shadow all PCI ROMs.
+  - Set up BDA and EBDA standard areas before the legacy boot.
+  - Construct the Compatibility16 boot memory map and pass it to the Compatibility16 code.
+  - Invoke the Compatibility16 table function Compatibility16PrepareToBoot(). This
+    invocation causes a thunk into the Compatibility16 code, which sets all appropriate internal
+    data structures. The boot device list is a parameter.
+  - Invoke the Compatibility16 Table function Compatibility16Boot(). This invocation
+    causes a thunk into the Compatibility16 code, which does an INT19.
+  - If the Compatibility16Boot() function returns, then the boot failed in a graceful
+    manner--meaning that the EFI code is still valid. An ungraceful boot failure causes a reset because the state
+    of EFI code is unknown.
