Hi,
I just found in [1] that the loongson hardware may eventually enable the execution of a live system (either from an USB drive or from a CD/DVD drive.
See [2], where pmon launches the system from an iso9660 filesystem
It sounds interesting. However, Im am not sure if this is a new feature introduced in the updated pmon, which runs on the recent 3A hardware, or if the "old" pmon used in the Fuloong/Yeeloong enables the booting from an iso9660 filesystem.
