If we were going to introduce a light weight block protocol like this,
I'd rather it be implemented in SeaBIOS as a block driver.

Ok. That would mean to replace the option rom with a seabios patch. The qemu code will be unmodified though (except for the rom loading).

Then we reuse
all of the int13 code, it gets registered as a BCV device allowing
selection in the boot menu,


and requires no special options on the
command line.

It would require a mechanism to do enumeration and identification though.

Huh? Do you want export *all* block devices via extboot? Will IDE drives show up twice then?

I would export only one and export it only on explicit user request, so it can be used for cases where seabios has no native support ...
