- Disables the 32-bit paging mode on the CPU.
-
- Disables the 32-bit paging mode on the CPU and returns to 32-bit protected
- mode. This function assumes the current execution mode is 32-paged protected
- mode. This function is only available on IA-32. After the 32-bit paging mode
- is disabled, control is transferred to the function specified by EntryPoint
- using the new stack specified by NewStack and passing in the parameters
- specified by Context1 and Context2. Context1 and Context2 are optional and
- may be NULL. The function EntryPoint must never return.
-
- If the current execution mode is not 32-bit paged mode, then ASSERT().
- If EntryPoint is NULL, then ASSERT().
- If NewStack is NULL, then ASSERT().
-
- There are a number of constraints that must be followed before calling this
- function:
- 1) Interrupts must be disabled.
- 2) The caller must be in 32-bit paged mode.
- 3) CR0, CR3, and CR4 must be compatible with 32-bit paged mode.
- 4) CR3 must point to valid page tables that guarantee that the pages for
- this function and the stack are identity mapped.
-
- @param EntryPoint A pointer to function to call with the new stack after
- paging is disabled.
- @param Context1 A pointer to the context to pass into the EntryPoint
- function as the first parameter after paging is disabled.
- @param Context2 A pointer to the context to pass into the EntryPoint
- function as the second parameter after paging is
- disabled.
- @param NewStack A pointer to the new stack to use for the EntryPoint
- function after paging is disabled.
