This is a pretty random question, I just couldn't find much specific info on Google. It'll tells me how to do it easy enough...
Motherboards being able to set a USB device as a boot device, how common is this? Mine can do it, can most newish computers boot straight from the device without some sort of floppy that then directs to the USB storage? If so, how old does a computer need to be before the BIOS may not support it? Not really asking for a specific reason, just occurred to me that I might be able to do some cool stuff this way
I know my laptop does, the model dates back to the end of 2003.
There a guide on a forum I visit a lot. It tells you how to make a bootable cd boot of a usb key chain.
Oh and you question I can't I think the latest firm wear I have is from 2003

My family has an old 450mhz Gateway, from around 2001/2002 or so, and it boots from USB.
I used to have an amptron board that I bought 2 years ago and it did not support usb booting. Then again it did not have support for many other features as well.
