Abstract:
EEH methods are used during the boot process to actively disable a defective PCI adapter, thereby allowing the system boot to continue without disruption. This allows faulty adapters to be present in the machine without interrupting the boot process. The slots appear to be empty and the devices/adapters residing therein can be actively “hot swapped” out without altering the rest of the machine state.
