System and method for interface isolation and operating system notification during bus errors

A method of notifying an operating system of a communications error, comprising:

• detecting a first error signal on a communications medium, the communications medium connecting a plurality of electronic devices;
• determining an electronic device associated with the first error signal;
• generating a hot-eject signal that identifies the electronic device associated with the first error signal;
• and
• blocking communications between at least one application and the identified electronic device with an operating system that includes device drivers in response to receiving the hot-eject signal.

An information handling system, comprising:

• a bus coupling a plurality of electronic devices;
• an operating system, including device drivers, capable of configuring communications between one or more applications and the plurality of electronic devices coupled to the bus;
• a detector coupled to the bus, the detector receiving error signals transmitted by the bus, one or more error signals associated with one of the electronic devices;
• and
• a BIOS coupled to the detector, the BIOS capable of determining an electronic device associated with a first error signal, the first error signal being a parity or system error signal, and the BIOS generating a hot-eject signal system control interrupt identifying that electronic device in response to the first error signal;
• wherein the operating system blocks communications between the applications and the identified electronic device in response to the BIOS generating the hot-eject signal system control interrupt.
