IPC: G06F9/06
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To update a device driver module which controls peripheral devices safely without once finishing an operating system to reboot in an information processing system. SOLUTION: An input-output state monitoring means 111 monitors the frequency of an input-output request that is issued to an old device driver 116 which operates before updation and detects a timing in which updation can be performed to a new driver 121 safely. An input-output pending means 112 monitors the end of an input-output request which is already received by the driver 116 and also makes a new input-output request a pending state. A device driver replacing means 113 includes the driver 121 in an operating system 11 and initializes it after unloading the driver 116. An input-output resuming means 114 executes the input-output request in its pending state at the new device driver and after that resumes normal input-output processing.
