Estimating the term…
A system for meeting demanding boot time requirements, such as those timing requirement mandated by vehicle telematics systems, is described. Current computer systems use expensive hardware like coprocessors to service requests, such as input/output requests, that have timing requirements which are less than the time required to load the operating system into memory. Instead, a mini-driver may be initialized early in the boot process before the operating system is loaded, to service these requests. For example, the mini-driver may buffer incoming data, and/or reply to incoming messages. After the operating system has loaded, a second device driver may be initialized, and the mini-driver may be transitioned to the second driver.
A method for operating a computer system, the computer system including an operating system, memory, and at least one peripheral device, the method comprising:
A method for servicing at least an input/output request during the boot process of a computer system, the computer system including an operating system including a kernel module and at least one peripheral device, where the at least one peripheral device is responsive to input/output requests, the method comprising:
A method for operating a computer system having an operating system and at least one peripheral component adapted to handle input and/or output data requests, the method comprising:
A method for operating a computer system having an operating system and at least one peripheral component adapted to handle input and/or output data requests associated with communications on a bus, the method comprising:
