did you also take a look at the code in sys/boot/i386/common? many functions in sys/boot/i386/boot2/boot2.c are also defined there and some seem to contain improved code. e.g. was the return type of xputc() changed from int to void, i think that's quite a resonable change and might reduce the boot2 binary size further. cheers. alex > > thank you! > > roman -- a13x _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
