[i4G0 <i4g0@libero.it>]

well, i need help. i'd like to install a debian system on my laptop.
that's an old Compaq Contura 410c
it has 8mb ram, 330mb hd. it's a 486 cpu. take a look at if you want to get 
more infos.
i have an Iomega Zip unit.. 
someone else installed a debian system from a zip disk? someone can help me 
installing it?
my problem is: how can i make a working ramdisk on my zip?
and also: how can i create a bootdisk that makes the zip work?
finally: which .deb should i choose? which is the base system? ftp archives? 
where?
thank you anticipately.
