Hi James, I am running OS5 rev2174..I needed to add a new HD , because my old HD would not partition and save the old data..

The MS came up with a command of skip, or correct error or ignore..on HD via keypad enter( after a few weeks of use)...but naturally , I could not without external hardware (Keypad)..

I have never seen this before.

I have also a problem ..no B4 since I installed rev2174...any suggestions..(email me please)..

Does the new OS use your new wavetable as default (left player) now instead of Dream chip?
