redhat distros and its nightmare
SMP: System multi Processor
UP: Uni-Processor system
Bigmem: If kernel is compiled to support over 1Giga of RAM
Enterprise: If kernel with extra options is installed, like bigmem + extras ( I remember something about virtual machine and swap, different from kernel standard )
I download srpm's, but you have to download closest to your system.
i386 work with al computers
i686 work with pentum II and above
Atlon work with AMD processors
and I think that Nvidia should do our live easy.
