Hackplement BOP_CMD function 0x08: "Launch external command". Still WIP. Explanation: Launching a command from command.com starts (under certain conditions not implemented there) "cmd.exe /c <the_command>" See https://groups.google.com/forum/#!topic/microsoft.public.win2000.cmdprompt.admin/n5KbegKJuE0 and http://technet.microsoft.com/en-us/library/cc723564.aspx#XSLTsection123121120120 subsection "CMD.EXE and COMMAND.COM": "Be aware that a command shell is not an MS-DOS command prompt, even though it shares the same icon. The Windows NT command shell is a full 32-bit Windows NT console application that resides in the CMD.EXE executable file. The MS-DOS command prompt is a 16-bit DOS application that resides in the COMMAND.COM executable file. Because COMMAND.COM is a 16-bit DOS executable, Windows NT executes this shell within a Windows NT virtual DOS machine (VDM). COMMAND.COM is supplied primarily for compatibility with MS-DOS. [...] This behavior reveals a quite subtle feature of Windows NT that is very important. The 16-bit MS-DOS shell (COMMAND.COM) that ships with Windows NT is specially designed for Windows NT. When a command is entered for execution by this shell, it does not actually execute it. Instead, it packages the command text and sends it to a 32-bit CMD.EXE command shell for execution. Because all commands are actually executed by CMD.EXE (the Windows NT command shell), the 16-bit shell inherits all the features and facilities of the full Windows NT shell." svn path=/branches/ntvdm/; revision=61290
======================== ReactOS Version 0.3.x Updated Dec 16, 2006 ======================== 1. What is ReactOS? ReactOS is an Open Source effort to develop a quality operating system that is compatible with Windows NT applications and drivers. The ReactOS project, although currently focused on Windows XP/2003 drivers compatibility, is always keeping an eye toward compatibility with older version of Windows NT family ( NT 4.0, 2000 (NT 5.0)) and new Windows NT releases (Vista, etc). Applications (Win32 API) compatibility focus is Windows XP. More information is available at http://www.reactos.org/. 2. Building ReactOS See the INSTALL file for more details. 3. More information See the media\doc subdirectory for some sparse notes. 4. Who is responsible See the CREDITS file.
