 When an XO-1.75 is locked in secure mode, an error processing bootfw.zip
 (corrupted signature, missing signature or image, etc.) results an XO-1.75
 immediately showing an unhappy face and scheduling a power off 30 seconds
 later.

 But if ecfw.zip is similarly corrupted, we get a message that the length
 of the firmware file is incorrect, and the boot process continues.

 Seen in Q4D04.
