Further to my previous reply:
I have forgotten to mention that on this thread:
I manged to install - trying again to save you the trouble to go through
all the posts of that long thread - Linux on such super old machine (P2
with 64MB RAM and 4GB HDD) by:
1- Taking the HDD out - because the machine itself has nothing to be
used to install Linux.
2- Plugged the HDD to another machine.
3- Linux installed - I wasted one month for this experiment because more
than 50 different systems didn't work - check the thread.
4- Disconnected the HDD and put it back in.
One month, ladies and gentlemen. Yes, I learned a lot and proved a lot
but the real result wasn't helpful for a daily use. Why? because these
machines can no longer serve while we are in 2014.
I was shocked when I managed to connect to the Wireless Network and
update the system. But that was the further I managed to go IIRC.
See the thread if you wish:
If anyone still think I'm wrong, see the thread :)
And first thing you do, check the date of that thread: October 8th, 2010
