Routine Description:
|
|
|
|
This routine examines a kernel image and determines whether it was
|
|
compiled for AMD64. The global BlAmd64UseLongMode is set to non-zero
|
|
if a long-modekernel is discovered.
|
|
|
|
Arguments:
|
|
|
|
LoadDeviceId - Supplies the load device identifier.
|
|
|
|
KernelPath - Supplies a pointer to the path to the kernel directory.
|
|
Upon successful return, KernelFileName will be appended
|
|
to this path.
|
|
|
|
KernelFileName - Supplies a pointer to the name of the kernel file.
|
|
|
|
Return Value:
|
|
|
|
The status of the operation. Upon successful completion ESUCCESS
|
|
is returned, whether long mode capability was detected or not.
