You can then capture the boot output on the second machine and e-mail that out. If it doesn't automatically use the serial console w/o a keyboard, you can do: set console="console" in the loader. By default, it uses 9660bps on com1. This is typically how we capture console debug output such as stack traces, debugger stuff, etc, since it doesn't rely on the system remaining up, and doesn't require you to type a lot of stuff in :-).
