2011 MBP boot from USB?

[salfred]

Maybe the 2011 MBP has disabled USB boot, any idea?

I replaced the original hdd with an Intel X25 ssd recently, with the SuperDrive replaced by the original hdd. (I use the mce optibay)
When I try to upgrade the firmware of my ssd, the new MBP refused to boot from "external superdrive". I've tried the win7/ubuntu cdrom, none of them worked.
It seems the new MBP will only boot from internal superdrive when it is exactly placed inside the machine.

Any solution here?

Just out of curiosity, were older models able to boot Windows or Ubuntu installation DVDs and CDs from an external USB ODD? I thought it is quite hard to boot Windows or the Windows installer from an external HDD or ODD.

How about you use the Intel CDRom ISO to make a bootable USB key (flash/thumb drive) and boot from the USB key? Seems like that would work. I have read tutorials about how to make a bootable Snow Leopard install on a USB key, seems like the same would work for the Intel boot ISO.

Let us know what happens. I'm now curious myself.
