The patch doesn't initialize serial port because it assume serial was already initialized by linuxbios. I think your problem is you didn't enabled debugs flags. you must enable DEBUG_ROMBIOS and also appropriate debug flags you want to see such as DEBUG_INT15, DEBUG_INT16 and etc.

Hello, I made a patch which make all bochs debug message can be seen from serial terminal. I think it might be useful if you want to apply ADLO to your own target. you can apply this patch againt util/ADLO/bochs/bios/rombios.c by # patch -p0 < rombios-serial.patch Regards,
