Can confirm 1.04b loader works on F4-220 without the video cable and setting the bios. Went from 1.02b 3615xs to 1.04b d981+ and there is no need for video cable atleast in my case. All the data and settings are preserved. First tried with a spare hard disk and spare usb worked perfectly then replaced with old hard disks and the migration is successful.
