No. It is a different configuration and it will take some work.
Part of the reason that serial is trivial is that we already have
a serial port driver for doing serial console.
LinuxBIOS is there to enpower you to do interesting things at the
firmware level.
The thing to be careful of is that while booting over the serial
port is trivial, and works well enough in a development situation,
it isn't reliable enough to use in production without some error
detection.
Even with the description I can't imagine when parallel port booting
would be a good deal.
