How to install NetBSD 2.0_BETA on a SGI O2 with MIPS R10000 CPU
---------------------------------------------------------------

Not yet tested with a O2 R5000, but should also work.

Download the Snapshot of NetBSD 2.0_BETA [1] from Christopher SEKIYA as he
had posted the information to the port-sgimips Mailinglist [2] and put it on
a local ftp server.

Setting up a tftpd Server, eg. comment out the following line in
/etc/inetd.conf and killall -HUP inetd:

tftp    dgram   udp     wait    nobody  /usr/libexec/tftpd      tftpd /tftpboot

Create the directory /tftpboot and gunzip
sgimips-2.0/binary/kernel/netbsd-INSTALL32_IP3x.gz to it as 
/tftpboot/netbsd-INSTALL32_IP3x

Configure your DHCP Server to bootstrap the SGI O2 from a TFTPd Server,
add the following host entry and restart dhcpd:

host sgi-o2 {
        hardware ethernet 08:00:69:05:fc:0f;	# the MAC address of the O2
        fixed-address 192.168.1.10;		# the IP of the O2
        filename "netbsd-INSTALL32_IP3x";	# the kernel file to load
        server-name="192.168.1.2";		# the server which runs tftpd
}

Now the fun starts ;)

Boot up your SGI O2 and press <Escape> or click on "Stop for Maintenance"
button at the startup screen. A manpage can be found at [3].

Select "5. Enter Command Monitor"

Check with hinv for the disks/cdroms which are available:

> hinv
                   System: IP32
                Processor: 195 Mhz R10000, with FPU
     Primary I-cache size: 32 Kbytes
     Primary D-cache size: 32 Kbytes
     Secondary cache size: 1024 Kbytes
              Memory size: 128 Mbytes
                 Graphics: CRM, Rev C
                    Audio: A3 version 1
                SCSI Disk: scsi(0)disk(2)
               SCSI CDROM: scsi(0)cdrom(4)

also check the current enviroments variables with printenv, the boot disk
(OSLoadPartition, SystemPartition) and the MAC address (eadddr) can be seen:

> printenv
AutoLoad=Yes
diskless=0
dbaud=9600
volume=80
sgilogo=y
monitor=h
TimeZone=PST8PDT
OSLoadPartition=pci(0)scsi(0)disk(2)rdisk(0)partition(0)
console=d
netaddr=192.168.0.2
SystemPartition=pci(0)scsi(0)disk(2)rdisk(0)partition(8)
OSLoadFilename=netbsd
osloadoptions=auto
OSLoader=boot
ConsoleOut=serial(0)
ConsoleIn=serial(0)
cpufreq=195
eaddr=08:00:69:05:fc:0f

Connect a null modem cable the the first com port of the O2 and to a free com
port on your computer and start a terminal programm (9600,8N1,RTS/CTS).

On the Command Monitor at the O2 change to boot up with the serial console:

> setenv console d

and reboot with:

> init

In a few seconds the system will boot up at the serial console, there press
<Escape> to again go into the Command Monitor and select again "5. Enter
Command Monitor".

Now set the IP address to the one configured in the dhcp server:

> setenv netaddr 192.168.1.10

either change SystemPartition to boot always from tftp with

> setenv SystemPartition bootp():

and boot with:

> boot

or boot with the following command from the Command Monitor:

> boot -f bootp():/netbsd-INSTALL32_IP3x

Now the NetBSD 2.0_BETA install kernel should be loaded, complete the
installation from the local ftp server. After the installation is finished,
reboot and go with <Escape> again to Command Monitor to set up booting
NetBSD from the local disk:

If the SystemPartition was changes before change it back to:

> setenv SystemPartition pci(0)scsi(0)disk(2)rdisk(0)partition(8)

And also set some other options (even if the SystemPartition was not
changed):

> setenv osloadfilename netbsd
> setenv osloadoptions auto
> setenv osloader boot

Now reboot to see if NetBSD boots up from the local disk

> init

If everthing went fine you should have a NetBSD running from the local disk.
