CAUTIONS:
1.
Not all bits are R/W. Therefore, be certain to keep a mirror image of
the register when programming it.
2.
All bits are 0 after a hardware RESET or power up condition.
As the supervisor I/O registers provide features associated to the TEKNOR Extension, the
TEKNOR Extension mode must be enabled by setting the W4 jumper that controls the
extended BIOS modes of the board (refer to Section 10 - Setting Jumpers).
