Well I figured I have nothing to lose. I messed up my woody install *real* bad by trying to fix libc6. I'm going to install potato and be happy.
Now, on ftp.debian.org : in /debian-cd/2.2_rev0/i386, there is 3 ISO images. Binary-i386-1.iso, binary-i386-2.iso and binary-i386-3.iso. I suppose I only need the 1st CD if I plan to install from internet anyways ?!
