Author: tkreuzer Date: Wed Aug 31 13:47:25 2011 New Revision: 53510
URL: http://svn.reactos.org/svn/reactos?rev=53510&view=rev Log: [FREELDR] - Massively refactor the winldr code - move common parts of LoadReactOSSetup and LoadAndBootWindows into LoadAndBootWindowsCommon - Combine architecture specific code into 2 functions: WinLdrSetupMachineDependent prepares the main stuff and WinLdrSetProcessorContext is the last thing done before transferring control to the kernel. - rename WinLdrTunOnPaging to WinLdrSetupMemoryLayout - Stop wasting stack space by decreasing the number of huge text buffers used - Don't handle x86 specific data like Tss in portable code - Add the progressbar for reactos setup as well - Add missing DPRINT_PELOADER to DEBUG_ALL
