However, ofw console is still too slow to work on.(IMO) I tried syscons + creator to get more speed by hardware acceleration. To build that kernel, I had to add <sys/modules.h> to source files. (I guess it was both sys/dev/fb/creator.c and sys/sparc64/creator/creator_upa.c) After really fast booting message scrolls and login prompt, the machine locked up. :( > later, > > Peter. > Regards, Pyun YongHyeon -- Pyun YongHyeon <http://www.kr.freebsd.org/~yongari>;
