NMI Parity Errors

With reference to IPB 4010. This states that switch 6 on block 2 should be set to the OFF position.

THIS IS NOT CORRECT!

The position of switch 6 on block 2 should always be set to the ON position, regardless of the revision of ROMs fitted.

On the question of NMI errors, systems suffering from spurious NMI errors should have their motherboards upgraded to board level 45 or greater. This upgrade applies only to the following machines:-

Qi 660/660i/660ti
VX1000M
VX FT (386)
