Reserved.
5
KBDDIS (Keyboard Controller Disable). When set to 1, this bit forces the Keyboard Controller module (Logical
Device 6) to be disabled (and its resources released) regardless of the actual setting of its Activation bit (index
30).
0: Enabled or Disabled, according to Activation bit (default)
1: Disabled
4
MSDIS (Mouse Controller Disable). When set to 1, this bit forces the Mouse Controller module (Logical Device
5) to be disabled (and its resources released) regardless of the actual setting of its Activation bit (index 30).
0: Enabled or Disabled, according to Activation bit (default)
1: Disabled
3
SER1DIS (Serial Port 1 Disable). When set to 1, this bit forces the Serial Port 1 module to be disabled (and its
resources released) regardless of the actual setting of its Activation bit (index 30).
0: Enabled or Disabled, according to Activation bit (default)
1: Disabled
2
SER2DIS (Serial Port 2 Disable). When set to 1, this bit forces the Serial Port 2 module to be disabled (and its
resources released) regardless of the actual setting of its Activation bit (index 30).
0: Enabled or Disabled, according to Activation bit (default)
1: Disabled
1
PARPDIS (Parallel Port Disable). When set to 1, this bit forces the Parallel Port module to be disabled (and its
resources released) regardless of the actual setting of its Activation bit (index 30).
0: Enabled or Disabled, according to Activation bit (default)
1: Disabled
0
FDCDIS (Floppy Disk Controller Disable). When set to 1, this bit forces the Floppy Disk Controller module to
be disabled (and its resources released) regardless of the actual setting of its Activation bit (index 30).
0: Enabled or Disabled, according to Activation bit (default)
1: Disabled
