So does that mean you only need the 1.5 update and not the full firmware file?
I had the full recovery file on the drive that was attached. Once the firmware install started, I wondered to myself if I could have just used the smaller 1.5 update file. It was too late to check at that point. Sorry.
And do you need to boot at least once from the stock drive before you update?
No, I don't think so. If you replace the stock drive before first boot I suspect you'll boot to same warning screen saying that something has happened to the System Software. In fact, if you don't care to do any testing I suspect this is the way to go about it. Otherwise you'll essentially have to start the initial setup over twice. Granted, the setup process is very simple and straightforward.
