Peter, thanks very much for the reply. But what I'm trying to do is actually the opposite of what you're saying. Let me explain it differently: The 9150's DRAM controller is an EDO controller. But the soldered 8 MB of DRAM on the 9150's mobo IS FPM, not EDO! That's the way 9150 mobos came from the factory. So presumably, if I installed EDO sticks into the 9150's SIMM slots, the DRAM controller would recognize the fact that they are EDO sticks, because it's an EDO controller... right? ..but I assume it would have to access the installed EDO sticks as FPM, because the soldered 8 MB of mobo DRAM is FPM. Wouldn't the controller be forced to access ALL installed RAM (soldered and sticks) in FPM mode because of the 8 MB of FPM DRAM that's soldered to the mobo? Please correct me if I am wrong about this last question; that's the answer I'm trying to determine. That's why I thought about removing the 8 MB of soldered FPM DRAM and replacing them with 8 MB of soldered EDO DRAM. Ultimately, the question is: Is the EDO capability of a 9150's controller rendered useless because of the fact that the soldered mobo DRAM is FPM? Looking forward to hearing from you! TIA...
