WD NMI Status
ENUM-. This bit reports that a hot swappable peripheral card has been installed or removed from the
system. A logical 0 means that ENUM- is not asserted on the backplane. A logical 1 means that
ENUM- is asserted on the backplane.
Reserved. These bits are reserved and should not be modified by the user.
Reserved. These bits are reserved and should not be modified by the user.
Board Revision. This port is used to read the status of cuttable traces CT8, CT18, CT19, and CT20
to determine the current board revision (Revision 0 = Fh). The user should not change these cuttable
traces since these values may be used by the system BIOS. These bits should be written as logical
0s when this register is modified.
