Thanks Mike, It is going to be an interesting week, I have never tried to install Linux in anything this sophisticated.

You should install the x86-64 version. The 64-bit compiled code should run faster so even if all your apps are 32-bit ... at least you'll have a 64-bit kernel. I've not checked how FC4 does it, but most 64-bit linux flavors install "32-compat" libraries also... some default to 64 bit in /lib and use /lib32, others default to 32 bit and provide a /lib64. > Is anybody aware of any potential problems?

On the x86 chip there I've not heard of any significant performance hit running 32 bit code when in 64 bit mode... the same code compiled in 64-bit mode often run faster because there are twice as many registers. _______________________________________________ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech _______________________________________________ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech
