Copyright (c) 1991 Microsoft Corporation
Module Name:
ntsetup.c
Abstract:
This module is the tail-end of the OS loader program. It performs all
IA64 specific allocations and initialize. The OS loader invokes this
this routine immediately before calling the loaded kernel image.
Author:
Allen Kay (akay) 19-May-1999
based on MIPS version by John Vert (jvert) 20-Jun-1991
Environment:

Routine Description:
This function initializes the IA64 specific kernel data structures
required by the NT system.
Arguments:
BlLoaderBlock - Supplies the address of the loader parameter block.
Return Value:
ESUCCESS is returned if the setup is successfully complete. Otherwise,
an unsuccessful status is returned.
