Re: external device
by Kees_B Forum moderator / November 30, 2011 5:56 PM PST seems to confirm (although it's for another model of Sony) that external device is a USB-device (flash, or possibly hard disk or CD/DVD-drive), but also notes a (special) setting to enable it (but that might just be on that model, of course).

I'd just try the external device and see what happens.

I have yet to see Sony offer upgrades to such.

But I have found such external boots to encounter limits. For example one laptop I own can't boot a bootable on other machines 8GB stick. But it does boot from 4GB and smaller sticks.

Since you didn't reveal much about this stick and if it works on what other machine I hope this gets you going.
