it's possible but it is going to be very hard... first of all, at 66mhz, and 8 mb or ram, you probably just want to stay with 3.1... even if you get Windows 95 working properly on that system, it's gonna run so slow that it's gonna make you want to cry... the other thing is, it's going to be really hard looking for drivers... especially a laptop... laptops are a b!tc4 to upgrade if the manufacturer does support the operating system you want... i am a primary laptop user too...
