I know that there are many Linux distros out there, I have actually been researching the best distros to use for a few months now.
Anyways, My main problem is the hardware. The laptop I'm trying to put it on is 17 years old, it has a Pentium 1 processor, only reads CDs, runs Windows 98, and can't connect to the internet. I've picked out Legacy OS (was called TEENpup), and so I'm really looking for help on what program to use to open it at the beginning (it comes in an iso format) and just general aid in how to use it.
