but a 700 MHz/512 MB machine is far below the minimum specs of any modern operating system at all - hence you even get not a Fedora/Ubuntu installer started full featured on it
I don't mean to call you foolish but I think that's a foolish statement. I use Gentoo which is a modern OS and the system in question surpasses the published hardware requirements for Gentoo on x86:

but not for Fedora and other distributions - period for the live-CD the *minimum* is 512 MB
well, you can't expect a fast system with *minimum* requirements it only says "it works somehow"
and yes i have servers with 512 MB RAM assigned but they do not run a GUI and this ones have no load
I'm going to fix the problem (probably by simply switching browsers) and the system is going to run perfectly well on its current OS.
