Having a WinXP x64 system here, I can assure you that it may be quite some time before everybody transitions to Win x64. The major problem is that you cannot use Win16 programs on WinXP x64 (we can be thankful that Linux doesn't have this issue, being 32 bit from the beginning). You would be shocked to find out how many _32-bit_ Windows programs use a Win16 INSTALLER, and thus will not INSTALL on WinXP x64, even though they would RUN there. WinXP x64 not having NTVDM or WoW32 is the source, although it appears that the claim is that x64 processors in long mode won't run 16-bit code at all. All in all I find the driver support for Linux of any version is better than the x64 driver support, XP or Vista, right now. Many many common hardware items that are a little older will simply not work on x64, and some of these have manufacturers that are at least publicly saying that they have no plans to support x64 systems on existing hardware. Some have 32 bit drivers that will at least take a modification to the .INF that will allow the driver to install, and sometimes even work; many hardware items simply won't work at all due to hardcoded assumptions about libraries and such (it's the same issue as multilib on linux). -- Lamar Owen Chief Information Officer Pisgah Astronomical Research Institute 1 PARI Drive Rosman, NC 28772 (828)862-5554 www.pari.edu
