Insyde F.33 doesn't it support a bootable pendrive?

I've tried several different ways to get linux mint to boot off a pendrive that I've formated correctly with Unetbootin. It seems maybe my bios doesn't support this. I've search for a update to and yet to find any, any help would be greatly appreciated.
