Motherboard jumper settings
There are only a few jumpers on the motherboard
that you may need to alter. All others are set at the
factory and should not be changed.
On the motherboard, pin 1 of each jumper block is
indicated by a small triangular marking.
Do not change jumper settings unnecessarily
Do not alter any jumpers or switch settings other than
those identified in this chapter, unless told to by your
Mitsubishi Electric PC supplier or an authorised
maintainer. Otherwise, you may damage the system
processor, the motherboard, or both.

On-board video disabling (J1)
If you install a video adapter expansion card, the
computer should automatically detect this and disable
the on-board video adapter. If for some reason this
does not happen, and you experience problems with a
newly-fitted card, you can manually disable the on-
board video adapter by moving jumper J1 from
position 2-3 (EN) to position 1-2 (DIS).
