underway should continue in spite of the failure to properly
initialize the device driver, or whether a new system boot
procedure should be initiated using the LastKnownGood control set
(210) of the registry (107). See Appellants’ specification page
10 lines 5-12. The LastKnownGood control set (210) contains a
data value that identifies a control set containing the data
values that last successfully booted the computer. See
Appellants’ specification page 8 lines 31-34. In response to a
successful boot from the Default control set (209), the
UpdateRegistry program (123) makes a new LastKnownGood control
set (210) that is equivalent to the Default control set (209)
which successfully booted the computer (105). See Appellants’
specification page 10 lines 19-23. In this way, it is ensured
that the computer (105) will successfully boot even after some
configuration data in the Default control set (209) has become
unusable. See Appellants’ specification page 10 lines 30-33.
Independent claims 23 and 26 present in the application are
