The only difference I noticed between 3.2 and 3.3 was that there was more autodetection, and in my case, I had to select noddc to disable the monitor detection as I had a laptop with an unrecognizable display.

Knoppix 3.3 has more autodetection.

Some LiveCD's are compiled for the 686 and up processors only, so they don't run on a AMDk6-2 at all.
Some distros, such as clusterknoppix, have a 2.88 meg bootimage instead of the 1.44 meg bootimage, which means that my old laptop freaks out when it sees it (Bios does not handle the 2.88 meg El Torito Booting)
In that case, I had to resort to using a Smart Boot Manager floppy disk to get past the bios booting.


newer distros tend to drop support for older hardware.
I doubt that anyone compiles for .386 any more.

some distros don't have knoppix's autodetect for everything, so they require the user to enter in stuff like screen resolution, depth, mouse type, etc.

Maybe when they update the cheatcode list, they should tell what new features they have in from the previous version.
