Most issues I have seen with this are usually BIOS issues that may or
may not ever get fixed. Various BIOSes play all kinds of games to boot
a cdrom, usb, etc by making it a virtual floppy. They then play
further tricks when doing chain booting and such.

In dealing with chain booting ISO's I know I have worked with projects
that did it for EL3/4/5 dvds. Depending on the hardware they would be
able to get to some of the ISOS but not all of them. [You would boot
and it would just hang.. ] Some would get fixed with BIOS updates..
some would not. Some would work doing it from USB keys, some would
not. Most would be the same hardware manufacturer and "model" but
different runs.

However this is old data from 2008 at the latest. I would expect this
to be less cutting edge and probably much more supported.
