Maybe this code could be encapsulated, similar to how VGA bios or network boot is handled.
Indeed, except that it relies on serial or USB support, which might not be easy to ship in a so encapsulated way.
Serial support is easy. USB is more of a problem as it needs a complete usb stack at bios time.
I remember discussing with the LinuxBIOS list a year or two ago, the issue of what to do when chipsets drop having any serial ports.
We are currently working on mainboard designs that will not have any serial ports with chipsets that don't have any serial ports. What did we decide to do with LinuxBIOS, since the future is now?
