a new try to install XP on a 486-system, Antz has succeeded to install it on a socket 3 mainboard (the last socket for 486 cpus). However he used a Pentium Overdrive. This very fantastic kind of technics has an original Pentium core, but with a 32-bit memory-controller specially constructed for the 486 socket.
Although he wasn't able to use a 486 CPU with this board and XP, he had to set up new records for mimum CPU and RAM
