New Revision: 25994
URL: http://svn.reactos.org/svn/reactos?rev=25994&view=rev
Log:
- Stub NtSystemDebugControl.
- Fully support _WINKD_. Change this to 1, and get kdcom.dll from Windows 2003 or TinyKRNL
and you'll be able to connect to WinDBG if using the right debug settings. You can now
boot to desktop with WinDBG connected and see debug messages, but not much else is
supported.
- Fix bugs in KeGetBugMessageText.
- Implement KeEnterKernelDebugger.
