You can get Debian to use your 128M of memory by passing a command to the kernel with your boot loader. I use lilo and this is what I put in my /etc/lilo.conf file
append="mem=80M" I put this right near the top of my lilo.conf file. You would have to use something like this append="mem=128M" there are how to's regarding this topic. You can do this with LOADLIN too. I hope you don't give up on Debian. Once you get through the initial bit you end up with a much more stable - robust system. (Note that I have use SUSE as well. It is pretty good but . . . Anyway don't forget this is about fun also. (Someone told me this a while ago and it helped.) I hope this has helped. MT
