Abstract
A system and method for boot failure recovery in a digital computer as a result of an attempt to load a procedure in which a flag is associated with the procedure following a loading attempt which results in failure. The flag is read on a further attempt to load the same procedure to initiate an orderly exit thereby avoiding the potential for entry into an endless loop.
Claims10
A method for recovering from a boot failure in a digital computer following an attempt to load a procedure, said procedure comprising a device driver configurable under the control of an entry in a database using identifier information obtained from adapter cards resident in said computer comprising the steps of:
- in response to load failure of a specific procedure, associating with said procedure a flag indicating that a loading attempt has resulted in boot failure by storing said flag in the entry in said database relating to the driver causing the failure;
- testing said procedure for an associated flag in a subsequent attempt to load such procedure;
- and
- aborting such subsequent attempt if such flag is detected.
A system for recovering from boot failure in a computer as a result of an attempt to load a procedure, said procedure comprising a device driver configurable under the control of an entry in a database using identifier information obtained from adapter cards resident in said computer, comprising:
- storage means for storing procedures to be loaded;
- means for selecting a procedure for loading from said storage means;
- flag means responsive to the occurrence of boot failure on loading of selected procedure to associate a flag with such selected procedure, wherein said flag is associated with the entry in said database relating to the driver causing the failure;
- and
- test means responsive to such flag to abort a subsequent attempt to load the associated procedure.
