Abstract: PROBLEM TO BE SOLVED: To provide a method, a system, and a device for allocating memorys to a plurality of extended slots in a data processing system. SOLUTION: In the initialization of the data processing system, the memorys are fixedly allocated between a plurality of extended slots 210-221 by means of firmware. If an input/output adaptor connected to one of a plurality of extended slots requires allocation of a larger quantity of memory than memory allocated previously, the memorys are allocated again. In execution, if the input/output adaptor requires a larger quantity of memory than that allocated to the slot for inserting the input/output adaptor, the firmware allocates the memory again from unoccupied extended slot, and then if necessary, from a selected extended slot selected from among occupied extended slots.

Abstract: A METHOD, SYSTEM, AND APPARATUS FOR MANAGING A FAILED INPUT/OUTPUT ADAPTER WITHIN A DATA PROCESSING SYSTEM (100) IS PROVIDED. IN ONE EMBODIMENT, AN OPERATING SYSTEM HANDLER (204) RECEIVES AN INDICATION THAT ONE OF A PLURALITY OF INPUT/OUTPUT ADAPTERS (222-228) HAS FAILED.THE OPERATING SYSTEM HANDLER CONSULTS AN ERROR LOG (300) TO DETERMINE WHICH INPUT/OUTPUT ADAPTER HAS FAILED. ONCE THE BAD INPUT/OUTPUT ADAPTER HAS BEEN DETERMINED, THE OPERATING SYSTEM HANDLER DISABLES THE BAD INPUT/OUTPUT ADAPTER AND DEALLOCATES ANY PROCESSES BOUND FOR THE BAD INPUT/OUTPUT ADAPTER WITHOUT POWERING DOWN THE DATA PROCESSING SYSTEM. A USER IS THEN NOTIFIED OF THE BAD INPUT/OUTPUT ADAPTER SO THAT THE BAD INPUT/OUTPUT ADAPTER CAN BE REPLACED. THE INPUT/OUTPUT ADAPTER MAY BE REPLACED WITHOUT POWERING DOWN THE DATA PROCESSING SYSTEM.ONCE THE BAD INPUT/OUTPUT ADAPTER HAS BEEN REPLACE, THE NEW INPUT/OUTPUT ADAPTER IS ENABLED.(FIG 1)
