Bebox revives
Hi! all,
I know bebox cannot be booted. However, I came to be able to boot with
the serial console by doing some corrections.
I will commit this patch after a few days.
However, the user land did not execute. init(8) did not execute though
I tried with binary 4.0 and 2.1 of prep.
By the way, I have the my great plan. It is to remove my i386 machine
(PenIII 1G), and to make bebox the main machine. ;-)
I do the cleanup of GENERIC as follows for this. And try to boot on vga.
Thanks,
