Appeal No. 2000-0257
Application No. 08/532,886
BACKGROUND
The appellant's invention relates to a control method and system for resetting backup
data. An understanding of the invention can be derived from a reading of exemplary claim
19, which is reproduced below.
19. A system comprising:
a connection board;
a plurality of circuit packages being detachably connected to said
connection board, each of the plurality of circuit packages using start-up
setting data for start-up operation;
a first package detachably connected to the connection board and
comprising:
a backup memory for storing the start-up setting data,
a disconnection detector for detecting disconnection of the first
package from the connection board to produce a disconnection signal, and
a state memory for storing one of a first state and a second
state such that the second state is normally stored and is changed to the first
state when the disconnection signal is produced; and
a second package for controlling the plurality of circuit packages and
the first package through the connection board, the second package being
detachably connected to the connection board and comprising a controller
for determining whether the start-up setting data stored in the backup
memory is valid by checking which of the first state and the second state is
stored in the state memory of the first package.
