+client. Performing this setup is quite time consuming, but necessary:
+
+
+
+ - First of all, the "nfs server" machine must be set up.
+ This needs to have a 800 MB /tftpboot partition.
+ Install NetBSD/pmax 2.0.2 from CDROM
+ inside the emulator. (Don't forget to add the extra partition!)
+
+
- Configure the nfs server machine to act as an nfs server.
+ Start up the emulated DECstation:
+ $ gxemul -M64 -Edec -e3max -d nbsd_pmax.img
+
and enter the following commands as root
+ inside the emulator:
+| |
+echo hostname=server >> /etc/rc.conf
+echo ifconfig_le0=\"inet 10.0.0.2\" >> /etc/rc.conf
+echo nameserver 10.0.0.254 >> /etc/resolv.conf
+echo 10.0.0.254 > /etc/mygate
+echo /tftpboot -maproot=root 10.0.0.1 > /etc/exports
+echo rpcbind=YES >> /etc/rc.conf
+echo nfs_server=YES >> /etc/rc.conf
+echo mountd=YES >> /etc/rc.conf
+echo bootparamd=YES >> /etc/rc.conf
+printf "client root=10.0.0.2:/tftpboot \\\n swap=10.0.0.2:/tftpboot/swap\n" > /etc/bootparams
+echo "10:20:30:00:00:10 client" > /etc/ethers
+echo 10.0.0.1 client > /etc/hosts
+reboot
+ |
+ - Start the DECstation emulation again, and download the
+ OpenBSD/sgi distribution:
(NOTE: This
+ takes quite some time, even if you have a fast network connection.)
+| |
+cd /tftpboot; ftp -i ftp.se.openbsd.org
+(log in as anonymous...)
+cd pub/OpenBSD/3.7/sgi
+mget b* c* e* g* m*
+quit
+sh
+for a in *.tgz; do echo $a; tar zxfp $a; done
+echo 10.0.0.2:/tftpboot / nfs rw 0 0 > /tftpboot/etc/fstab
+dd if=/dev/zero of=swap bs=1024 count=32768
+halt
+ |
+ - Download the OpenBSD/sgi GENERIC and RAMDISK kernels:
+ ftp://ftp.se.openbsd.org/pub/OpenBSD/3.7/sgi/bsd
+ MD5 (bsd) = f16eaf3dcbd51876db7c25f70e6d8a08
+ ftp://ftp.se.openbsd.org/pub/OpenBSD/3.7/sgi/bsd.rd
+ MD5 (bsd.rd) = 4843e6139d8dd04b03d5f0e33e9a4f7b
+
+
+ - Create a configuration file called config_client:
+
| |
+!!gxemul
+!
+! Configuration file for running OpenBSD/sgi diskless with
+! a NetBSD/pmax machine as the nfs server.
+!
+! This config file is for the client.
+
+emul(
+ net(
+ add_remote("127.0.0.1:12444") ! the server
+ local_port(12445) ! the client
+ )
+
+ machine(
+ name("client machine")
+ serial_nr(1)
+
+ type("sgi")
+ subtype("o2")
+
+ ! load("bsd")
+ load("bsd.rd")
+ )
+)
+ |
+ ... and another configuration file for the server,
+ config_server:
+| |
+!!gxemul
+emul(
+ net(
+ local_port(12444) ! the server
+ add_remote("127.0.0.1:12445") ! the client
+ )
+
+ machine(
+ name("nfs server")
+ serial_nr(2)
+
+ type("dec")
+ subtype("5000/200")
+
+ disk("nbsd_pmax.img")
+ )
+)
+ |
+ - Boot the "nfs server" and the OpenBSD/sgi
+ "client machine" as two separate emulator instances:
+ in one xterm:
+ $ gxemul @config_server
+
+ and then, in another xterm:
+ $ gxemul @config_client
+
+
+ - In the OpenBSD/sgi window, choose "S" (for Shell), and type:
+
| |
+ifconfig mec0 10.0.0.1; route add default 10.0.0.254
+mount -v 10.0.0.2:/tftpboot /mnt
+cd /mnt/dev; ./MAKEDEV all; cd /; umount /mnt
+halt
+ |
+
+
+You might want to log in as root on the server machine, and
+run tcpdump -lnvv or similar, to see that what the client machine
+actually does on the network. The MAKEDEV script takes almost
+forever, so be patient.
+
+
NOTE: Everything up to this point should work.
+However, the next step (in gray) doesn't actually work:
+
+
Once everything has been set up correctly, change
+bsd.rd in config_client to just bsd (the GENERIC
+kernel). It should now be possible to boot OpenBSD/sgi using the NetBSD/pmax
+nfs server. (When asked for "root device :" on the OpenBSD machine,
+enter mec0.)
+
+
But it doesn't work. Probably because GXemul's
+implementation of the mec (ethernet card used in the O2) is too much of
+a quick hack. For now, use the bsd.rd kernel, and (at every
+boot) type:
+ s (for Shell)
+ ifconfig mec0 10.0.0.1; route add default 10.0.0.254
+ mount -v 10.0.0.2:/tftpboot /mnt
+ cd /mnt; usr/sbin/chroot .
+ sh etc/rc
+
+
+This will not cause OpenBSD to be booted
+normally, but at least a few basic things will work.
+By the way, the emulator performs so poorly, that you will have time to
+fetch several cups of coffee for each of the steps above.
