Windows XP build 2505 (Lab01 N)

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), likely a private compile by Dave Cutler, the primary architect of the NT kernel. He was leading the development of Windows for AMD64 at the time of the compilation of this build, so the files being present in the source tree may be related to this.
