i think 040 give _VERY_ slow transfer (any types). and
overclocking only resoldering resitor not good idea, need speedup oscilator from 66 to 70/etc. And of course need
change 040 to 060. So, i realy need too little help about
change 060 on 040.
if divx on PPCx300+/060x66 not playing fine - change
all ide on scsi,etc .. but i think, just little 040->060 change REALY speedup system (any tranfers), and divx playing.
