NetBSD/pmppc can run in GXemul on an emulated Artesyn PM/PPC board. Currently, no SCSI or other disk controller is emulated for this machine type, but it is possible to run NetBSD with root-on-nfs.
These setup steps will let you run NetBSD/pmppc with root-on-nfs:
gxemul -e 3max -d nbsd_pmax.imgand 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 "bootps dgram udp wait root /usr/sbin/bootpd bootpd -d 4 -h 10.0.0.2" >> /etc/inetd.conf cat >> /etc/bootptab client:\ :ht=ether:\ :ha=102030000010:\ :sm=255.0.0.0:\ :lg=10.0.0.254:\ :ip=10.0.0.1:\ :rp=/tftpboot: (press CTRL-D) echo "10:20:30:00:00:10 client" > /etc/ethers echo 10.0.0.1 client > /etc/hosts reboot |

gxemul -e 3max -d nbsd_pmax.img -d pmppccd-3.1.isoand extract the files from the PM/PPC CD-ROM image to the DECstation disk image:
cd /tftpboot; mount /dev/cd0a /mnt for a in /mnt/*/binary/sets/[bcemt]*; do echo $a; tar zxfp $a; done echo 10.0.0.2:/tftpboot / nfs rw 0 0 > /tftpboot/etc/fstab echo rc_configured=YES >> /tftpboot/etc/rc.conf echo 10.0.0.254 >> /tftpboot/etc/mygate echo nameserver 10.0.0.254 >> /tftpboot/etc/resolv.conf echo rc_configured=YES >> /tftpboot/etc/rc.conf dd if=/dev/zero of=swap bs=1024 count=65536 cd /tftpboot/dev; sh MAKEDEV all cd /; umount /mnt; halt |
! Configuration file for running NetBSD/pmppc diskless with ! a NetBSD/pmax machine as the nfs server. net( add_remote("localhost:12444") ! the server local_port(12445) ! the client ) machine( name("client machine") serial_nr(1) type("pmppc") load("netbsd-PMPPC.gz") ) |
net( local_port(12444) ! the server add_remote("localhost:12445") ! the client ) machine( name("nfs server") serial_nr(2) type("dec") subtype("5000/200") disk("nbsd_pmax.img") ) |
It should now be possible to boot NetBSD/pmppc using the NetBSD/pmax nfs server, using the following commands: (NOTE! Execute these two commands in separate xterms!)
gxemul @config_server gxemul @config_client
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.
When asked for "root device:" etc. on the client machine, enter the following values:
root device: tlp0 dump device: (leave blank) file system (default generic): (leave blank) .. init path (default /sbin/init): (leave blank)
