Windows XP build 2505 (Lab01_N) is a build of Windows XP. The boot loader files for this build are present in the Windows XP source code.

It is worth noting that these files are, considering the username (davec) and branch (Lab01_N, kernel team branch), a private compile by David Cutler, the primary architect of the NT kernel, who led the development of Windows for AMD64 at the time of the build's compilation. It is possible that the files' presence within the source tree may be related to the AMD64 variant of Windows XP.

Also, the Windows Server 2003 DDK and source code contains the Windows NT Message Compiler (mc.exe) program, which was compiled by the user bryant on 27 June 2001.
