I had to do a hard power off on my Pi, as it had crashed. Now, when I turn it on, I get 3 flashes of the OK LED, which means either loader.bin or start.elf is not found. I have plugged the SD card into my Windows PC to browse the boot partition and neither of those files is present. Is there any way to repair the boot partition and allow the Pi to boot without losing any data on the card? I have important data that hasn't been backed up yet on the card.


Question: What does the Customer is_active flag do?
Answer: This is a legacy field, derived from Mage_Eav and present as far back as v0.7.14800 (and perhaps earlier). As such, it by far predates the earliest version of EE.

Whether the value of this field is used or not is a matter of implementation  (such as it is for the catalog_category entity). I base this assertion on the fact that the Mage_Eav module does not provide any use of it as a base behavior for EAV entities.
