My thanks to this list for helping me get this 2400 tamed. Trackpad is behaving now, even trackpad button, slow typing has stopped. The change occurred when I installed 7.6.1 and used Ram doubler. I also initialized the hd. it booted up with a borrowed 3400 7.6 disc and thereafter without disc. Only once did I get the disc with the question mark. a lot of it is learning how to keep your hand away from the trackpad button when typing. I have wide stubby hands, meant more for farmwork than typing on a computer. but our family has not farmed in two generations. Only problem I have now is an occasional flickering of the screen......oh, Lord. but I am not going to start worrying.......yet.
