a little while back i was bored so i pulled an old crappy dell p4 out of the basement, loaded it up with ram, and connected a CF to ide adaptor to it.
then i used a tool called wintousb to install tiny 7 to the CF card and booted the pc from that.
it did take some fiddling.
then i got all the drivers installed along with attractmode and advmame.
set it up so it booted to attractmode and then booted it up, played some games then pulled the plug.
did it about 15 times.
no corruption.
