you are absolutely right. Internally, PC GAMESS/Firefly
uses the following simplified classification of Operating Systems
(in no particular order):

1. DOS
2. OS/2
3. Win9x (Windows 95, Windows 98, Windows Millennium)
4. NT (Windows NT 3.x-4.0, and all the subsequent NT core Windows versions (both 32-bit and 64-bit):
Windows 2000, Windows XP, Windows 2003 Server, Windows Vista, Windows 2008 Server, and future Windows Seven).
5. Linux
6. Wine running under Linux or other OS.

For each OS class, there is predefined set of optimal defaults,
as well as list of non-supported options, features, and system calls
(e.g., those related to memory management, I/O, etc...)

Regards,
Alex

>Why do you think that the OS is not properly identified? Windows XP is a Windows NT operating system. �More specifically it is a particular build of version 5.1 for XP Pro 32-bit, and version 5.2 for XP Pro 64-bit. I would think it very rare that the OS and hardware detection fails to properly identically the software and hardware of the system correctly (it has never happened for me anyway), although I suppose it is possible but just not in this case.

>The Windows builds are unified as to the software (referring to your OS detection) but are specific to the processor architecture. If you are using the wrong version for your particular hardware a warning will be printed out near the start of the output file stating this. Based upon the CPU detection, I believe that the P4 version should be fine for your system.
