The example workaround circuit assumes that the PWRGD inputs into the processors are open

collector. Tying the PWRGD inputs together in a Wired-AND fashion allows each processor to receive

PWRGD at the same time but at the latter of the 2 separate PWRGD assertions. If separation of the

PWRGD inputs to each processor is required, extra circuitry will be required.

Status: For the steppings affected, see the Summary of Changes at the beginning of this section.
