IOP passes POST.
IOP tests MIC BIOS and
calls MIC BIOS.

BIOS.
System BIOS starts to
load Windows NT*.

Offline to Ready.
* For an IOP to service the CE boot request, it must have reached the appropriate completed
boot. The IOP that services the boot request is one of the following:
- If both IOPs are present and are identical, the first IOP to initialize services the CE boot request.
- If both IOPs are present and not identical, the IOP with the most current disk services the CE boot
request.
- If one IOP is available, and if the server is configured to boot with only that IOP, the only available IOP
services the boot request.
