2 Celeron 600, 128 RAM
3 PIII, 500, 64 RAM
4 PIII, 500, 64 RAM

Only can 1 openSUSE (Main memory: At least 256 MB) computer, want to install Linux in all other low-performance computers.
How can I get their distribution? I need CD without virus.

This Linux (other 3 computers) can network and cooperate with openSUSE?
