KdDebuggerEnable is now set whenever booting with debugging -- even if only serial port or screen debugging. - Complete cleanup and major rewrite/improvement of bugcheck code: - Moved stack dump routines to bug.c and cleaned them up. Next step is to remove most of them and implement them properly as part of RtlCaptureStackBackTrace and RtlWalkFrameChain. - Use InbvDisplayString for everything now. BSODs will only truly show on screen. (however, part of the KeBugCheckWithTf improvements, a special "if debugger enabled" BSOD will also be displayed for debugging purposes). - Do checksum calculation in bugcheck callbacks. - Detect and display which drivers belong to which EIP. - Implemented code to select the proper verbose BSOD message depending on the bug check code. - Also implemented code to detect a variety of "known" bug check codes and to recover more data on them, and/or modify them accordingly. Sadly ROS doesn't yet make use of most of these codes. - Factored out and split some code into individual routines. - Look and functionality is now identical to Windows XP. - Stack trace will only be shown if KDBG isn't connected. If KDBG is connected you can do "bt" anyway (which is more powerful).
