Yes.. basically.

>What are we doing that needs IHU-2 at full speed?

It's more a convenience than the need for the speed.  The FLASH ROM is 
currently loaded with this software and it's simple to reboot from the
ROM. 
To fix things we'll have to reload the flash, etc......  It'll wait
until 
after the burn, etc...
