So far I've tried to boot

ubuntu-6.10-desktop-i386
xubuntu-7.10-desktop-i386
debian-live-40r0-rc1-i386-xfce-CD

on my old secondary PC which is a Pentium MMX 200/160 MB RAM. In all 3 cases the boot procedure stops at SquashFS, I don't even get to see the 'done' message. How can I narrow the problem down? Thx.
