I see now that you are using a Fuloong and not a Loongson. I tested
the above steps on a Loongson to make sure my memory of things was
correct, but the same instructions should apply to Fuloong, though I
haven't used vga console on a Fuloong since ages. I prefer serial
access and it works as it should after the "magic" steps described in
the INSTALL document.
