Distros that don't use legacy boot0?

[gregjo]

lennyraposo's builds ( a year ago ) used the boot0 ,  and his builds had serial console boot log running fine.

... if Fedora does not have a serial console boot log ,  that will eventually ( if not right now ) be a problem for them;  on your end make sure you're using the right baud rate ( they may have changed to a higher rate 1.5M ? )  so check with them.

I found my problem...the serial console cable. It worked fine with boot0-based distros, but failed with the newer SPL code. I swapped to a different cable, and can now see Fedora booting. :-)

I'm still baffled why that old cable worked with boot0, and not the newer code.
