Chris, on my machine the procedure involved 3 steps: 1) Move jumper at J101
2) Cut trace at jumper pad J500 3) Pull old Agnes (by far the hardest part)
and install new Agnes Mine is a revision 4.5 motherboard and I understand
from my local service guy that installation on older boards may involve
first updating motherboard to 4.5 and then performing the installation as
outlined above. I think I might of gotten lucky this once… Rick
