Hi hackers,
I'm trying to get my Genuine 386 running 7.2. It currently runs 4.11.
386 was first base of FreeBSD, a shame to lose it.
So far I've hacked diffs as below + the normal
/etc/make.conf CFLAGS += -march=i386
cross compiled all bins libs etc &
setenv DESTDIR /usr/7.2 i
cd /usr/src/etc l make distrib-dirs
cd .. ; make install
But manually unloading 4.11 kernel & loading 7.2 kernel & booting
doesnt yet boot far enough to encourage me to move bins yet,
I think I need to do a bit more kernel before that ?
This is what I gave so far. Input welcome.
