Talk:386BSD
You can get 386BSD to run in a patched bochs 2.4.2, full blown with all the patches, triple make world, the works. Ok, ok, try to compile perl-5.10.1 and the compiler segfaults, but what is in the distro works. Everything works. There exists a broken (in a mere two pieces) shell script that reproduces a bochs image and environment on an AWS default fedora server. The script is of such questionable and perverted command line art that it is deemed unredistributable in its current form. It can be done! Dugo
Can you give more details? Suddenly this is interesting again... !

Ok here goes. Take a eg. Basic Fedora Core 8 box and install required software.
yum -y install wget yum -y install gcc yum -y install gcc-c++ yum -y install ncurses-devel yum -y install vsftpd
The 386BSD bootflop does something odd. The workaround is to patch bochs to ignore it instead of panic when 386BSD tries to write 0x02 to port 20h.
# get bochs
cd /usr/local/src
wget http://downloads.sourceforge.net/project/bochs/bochs/2.4.2/bochs-2.4.2.tar.gz?use_mirror=kent
gunzip -c bochs-2.4.2.tar.gz |tar -xvf -
wget http://www.xs4all.nl/~dugo/pic.cc
mv -f pic.cc ./bochs-2.4.2/iodev/pic.cc
cd bochs-2.4.2
./configure --enable-cpu-level=3 \
--enable-ne2000 \
--with-term \
--with-nogui \
--enable-all-optimizations \
--enable-docbook=no
make && make install
During installation the 386BSD distribution files can be fetched with ftp. To facilitate this set up an anon ftpd that serves up the files. There is a catch 22. 386BSD comes without gzip, but the patches are gzipped, here your chance to get around that.
echo listen=YES >> /etc/vsftpd/vsftpd.conf vsftpd cd /var/ftp wget -r -np ftp://minnie.tuhs.org/BSD/386bsd-0.1/ wget -r -np ftp://minnie.tuhs.org/BSD/386bsd-patchkits/ mv minnie.tuhs.org/BSD ./ rmdir ./minnie.tuhs.org cd /var/ftp/BSD/386bsd-patchkits gunzip *gz
To make bochs' ne2k work without a spare NIC in your host you need to set up tunneling.
echo alias char-major-10-200 tun >>/etc/modprobe.d/modprobe.conf.dist depmod -a ln -s /dev/net/tun /dev/net/tun0
Make a tunconfig script for bochs to fire off when the ne2k comes up. In this example 192.168.1.1 becomes the gw and you can pick an ip in 192.168.1.0/24 for the guest later.
# set up the bsd dir w/ tunconfig
cd; mkdir bsd; cd bsd
printf '#!/bin/bash\n/sbin/ifconfig ${1##/*/} 192.168.1.1\n' >tunconfig
printf 'date; echo ${1##/*/} >/tmp/x' >>tunconfig
cat >>tunconfig <<__EOF
# carnival, put your masks on and go
/sbin/iptables -D POSTROUTING -t nat -s 192.168.1.0/24 -d ! 192.168.1.0/24 -j MASQUERADE >& /dev/null
/sbin/iptables -t nat -s 192.168.1.0/24 -d ! 192.168.1.0/24 -A POSTROUTING -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward
__EOF
chmod +x tunconfig
The 386BSD installation fails on a box with a lot of mem, hence the `megs: 8' stanza in the bochs configuration.
cat >bochsrc <<__EOF config_interface: textconfig display_library: term romimage: file=/usr/local/share/bochs/BIOS-bochs-legacy cpu: count=1, ips=80000000, reset_on_triple_fault=0 megs: 8 vgaromimage: file=/usr/local/share/bochs/VGABIOS-lgpl-latest vga: extension=none floppya: 1_44=boot.img, status=inserted ata0: enabled=1, ioaddr1=0x1f0, ioaddr2=0x3f0, irq=14 ata0-master: type=disk, path="disk.img", mode=flat, cylinders=1024, heads=16, spt=63, translation=none, model=generic boot: disk, floppy floppy_bootsig_check: disabled=0 log: bochsout.txt panic: action=ask error: action=report info: action=report debug: action=ignore vga_update_interval: 400000 keyboard_serial_delay: 250 keyboard_paste_delay: 1000000 mouse: enabled=0 private_colormap: enabled=0 keyboard_mapping: enabled=0, map= i440fxsupport: enabled=0 ne2k: ioaddr=0x300, irq=9, mac=fe:fd:00:00:00:01, ethmod=tuntap, ethdev=/dev/net/tun0, script=/root/bsd/tunconfig com1: enabled=0 __EOF
Prepare the 386BSD boot floppy for our box with a fancy 1.44MB floppy drive.
(cat /var/ftp/BSD/386bsd-0.1/bootable/dist.fs;dd if=/dev/zero bs=1 count=245760)>boot.img
Make a hard drive for the installation.
rm disk.img; printf "hd\nflat\n504\ndisk.img\n" |bximage
You should now be able to fire up bochs in your terminal and start your journey back in time.
bochs -q -f bochsrc
Bochs will come up booting a tiny 386BSD from floppy, this needs to go to disk, which can be done with a simple
(echo y; echo y)|install
Now try to reboot with..:
shutdown -r now
..this will go horribly wrong but don't panic. Boch will probably crash, just fire it up with..:
bochs -q -f bochsrc
386BSD comes up and shuts down immediately causing bochs to crash again. This is a reoccuring theme, don't worry about it and fire bochs up again anytime this happens. Next, the real work, installing the distro.
The tiny 386BSD kernel keeps kprinting `startartstartart' to your screen once network is up and running. This can get on your nerves, so try to do as much as possible with shell scripts. In this case everything just goes into .netrc.
Extract will complain about something being missing, according to an ancient FAQ this is a joke from Jolitz. Extract also opens more files than tiny 386BSD sh can handle, hence the use csh.
Change the ips below, 10.0.0.1 to where your ftpd lives, 192.168.1.1 to your gw and 192.168.1.2 to the ip you want to give the guest. Change odin into the name you want to give the guest.
echo "machine 10.0.0.1" >.netrc echo "login ftp" >>.netrc echo "password news@EU.net" >>.netrc echo "macdef init" >>.netrc echo "#" >>.netrc echo "pasv" >>.netrc echo "prompt" >>.netrc echo "bin" >>.netrc echo "lcd /tmp" >>.netrc echo "cd BSD/386bsd-0.1/bindist/" >>.netrc echo "mget *" >>.netrc echo "cd ../etcdist/" >>.netrc echo "mget *" >>.netrc echo "cd ../srcdist/" >>.netrc echo "mget *" >>.netrc echo "cd ../../386bsd-patchkits" >>.netrc echo "mget *tar" >>.netrc echo "!echo odin |extract bin01" >>.netrc echo "!csh -c \"limit openfiles 512; extract src01 ; extract etc01 ; tar -cf /dist.tar /tmp/ ; cp pk023.tar /pk023.tar ; cp pk023024.tar /pk023024.tar ; sync ; sync ; sync ; /sbin/shutdown -r now\"" >>.netrc echo "quit" >>.netrc echo "#newl" >>.netrc echo "" >>.netrc chmod 400 .netrc # .netrc is now ready to do the installaion # fire up the network and go, go go ifconfig ne0 192.168.1.2 netmask 255.255.255.0 up route add default 192.168.1.1 ftp 10.0.0.1
When all goes well bochs crashes when 386BSD shuts down. Restart twice and 386BSD should greet you with a login prompt and scold you for loging in as root (no password) when you do. Next up, patch the system and do a buildworld. Dugo
Now run the first pile of patches.
cd / tar -xvf pk023.tar mv patch /dist cd /dist cd bin ./mkpatchdirs cd /patch cd bin (echo y; echo; echo; echo IALL; echo y ; echo ; echo q)|./patches cd /patch cd bin sh -x afterinstall.sh
Recompile the GENERIC kernel.
rm -r /sys/compile/* cd /sys/i386/conf config GENERICISA cd /sys/compile/GENERICISA make depend make mv /386bsd /386bsd.old cp 386bsd /386bsd sync; sync; sync; reboot
When bochs goes down because of the reboot, up the amount of mem or the following will take ages.
cd /dist/bin buildworld.sh sync; sync; sync; reboot
Now do it all again with the second patch set.
cd / tar -xvf pk023024.tar cd patch/bin (echo y ; echo ; echo ; echo IALL ; echo y ; echo ; echo q )|./patches sh -x afterinstall.sh rm -r /sys/compile/* cd /sys/i386/conf config GENERICISA cd /sys/compile/GENERICISA make depend make mv /386bsd /386bsd.old cp 386bsd /386bsd sync; sync; sync; reboot
cd /patch/bin ./buildworld.sh sync; sync; sync; reboot
For good meassure and proof the box works do another buildworld. Then go do something fun with it. Hack a uname system call into the kernel, fix the ancient zoneinfo, fail at getting ssh to work on it, etc..
If something is broken in the commands/scripts above, sorry, I fsckd up, but they should contain enough hints to get a 386BSD box emulated. Dugo Dugo
- Very interesting. I was using the 0.1 release for a short while when it came out, the reason I switched over to Linux 0.95 (early 1992) was IIRC something about the disk usage - I seem to recall that 386BSD wanted the whole disk while it was easy enough to partition with Linux. Or something other that made it easier to let Linux co-exist. Fuzzy memory. -- Tor 13:43, 30 June 2010 (UTC)
Damn dude, that's like an install article... feel free to write one (use any tutorial as a template if you want) or I'll just do it...
Thanks that's some great work thought!!!!!!

I'll try to iron out any misdirections in the above and fold it into a networking with bochs and a 386BSD on bochs tutorial. Dugo 10:23, 5 April 2010 (UTC)
Awesome job so far! neozeed 20:40, 9 April 2010 (UTC)
Getting there. While I think it is important to have this piece of history (386BSD 0.1 + patchkits) preserved for future emulator use there is something missing. Anyone with a clue where I can get an ISO of the 386BSD 1.0 release William & Lynne Jolitz show off on their website http://www.386bsd.org/past ? Dugo 05:26, 13 April 2010 (UTC)
