Enables the 32-bit paging mode on the CPU.
|
||||
|
||||
Enables the 32-bit paging mode on the CPU. CR0, CR3, CR4, and the page tables
|
||||
must be properly initialized prior to calling this service. This function
|
||||
assumes the current execution mode is 32-bit protected mode. This function is
|
||||
only available on IA-32. After the 32-bit paging mode is enabled, 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.
|
||||
|
||||
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 protected mode with flat descriptors. This
|
||||
means all descriptors must have a base of 0 and a limit of 4GB.
|
||||
3) CR0 and CR4 must be compatible with 32-bit protected mode with flat
|
||||
descriptors.
|
||||
4) CR3 must point to valid page tables that will be used once the transition
|
||||
is complete, and those page tables must 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 enabled.

|

function as the first parameter after paging is enabled.
|

@param Context2 A pointer to the context to pass into the EntryPoint

function as the second parameter after paging is enabled.
|

@param NewStack A pointer to the new stack to use for the EntryPoint
|

function after paging is enabled.
