Revision as of 04:53, 8 May 2024

Hardware

Octane:

  • IP30, Single 400 MHz R12000 CPU
  • 1 GB RAM (fully populated)
  • Odyssey Graphics (V8)
  • 173 GB Fujitsu Disk (SCSI ID 1)
  • Monitor: Dell 2007FP using 13W3-VGA converter
    • Vertical: 56 Hz - 76 Hz (except 1600 x 1200: 60 Hz only)
    • Horizontal: 30 kHz - 81 kHz
    • SGI can drive 1024 x 768 / 75 Hz

Can use last IRIX version (6.5.30, released 2006-08).

See here for information on DAT drives that can play audio.

Disk Partitions

  • 0: root filesystem
  • 1: swap
  • ...
  • 6: usr filesystem
  • 7: entire usable portion, excluding volume header
  • 8: volume header
  • 9: non-SCSI bad block list
  • 10: entire disk, including volume header
  • ...
  • 15: XFS log

From PROM:

  • SystemPartition=xio(0)pci(15)scsi(0)disck(1)rdisk(0)partition(8)

Command Monitor ARCS (PROM)

Some commands (See full list here):

  • help
  • init
  • hinv
  • printenv
  • setenv
  • unsetenv
  • passwd
  • boot -f bootp()...
    • or just bootp()...

Note:

  • Set keyboard variable: keybd, eg "US" or "GB".
  • Previous line: CTRL-P
  • Disk specification: dksc(0,1,0)/file (for SCSI controller 0, unit 1, partition 0)

The "ping" command does not use ICMP echo, rather obsolete echo (7/udp), eg: 

09:37:49.278482 IP 0.0.0.0.3152 > 10.0.0.1.echo: UDP, length 64
09:37:49.278674 IP 10.0.0.1.echo > 10.0.0.2.3152: UDP, length 64

The IP "0.0.0.0" is used if the netaddr PROM variable is not set.

Network installation

In this procedure, we will use a BOOTP server to tell the SGI's PROM where to find in the Installation tools via TFTP. The installation tool itself obtains the full installation via RSH. These services are provided by a docker instance; this was running on Fedora 35.

  • Ensure no other BOOTP or DHCP servers are running on the network
  • Services are highly insecure, so recommend running for short time on isolated network
  • For this example:
    • sgi : 10.0.0.2
    • lin-docker : 10.0.0.1

To monitor traffic, this tcpdump command is useful: 

tcpdump -i any -v -nn "portrange 67-69 or port 514 or port 7"

CD Images

See here for list of SGI CD numbers. EFS CD images can be converted with efs2tar or download the tar archives.

Create structure installation, eg: 

mkdir /home/user/irix
cd /home/user/irix

Download and extract tar archives to suitable subdirectories:

Common prerequisites for other packages:

Optional, but recommended:

See here for Aug 2006 Freeware

Freeware (Feb 2003):

  • 812-0773-019 Freeware 1 : fware1
    • autoconf
    • apache2
    • bash
    • curl
  • 812-0964-019 Freeware 2 : fware2
    • gcc
  • 812-1085-019 Freeware 3 : fware3
    • make
    • md5
    • openssh
    • postgresql
  • 812-1137-019 Freeware 4 : fware4
    • samba
    • teTeX
    • zfig
    • zip

SGI

Esc to enter SGI Command Monitor (PROM) and note the MAC address: 

printenv eaddr

The BOOTP server does not to respond unless an IP is set to match what it has for the client: 

setenv netaddr 10.0.0.2

Docker Setup

This docker image provides the services:

  • echo (7/udp)
    • For response to PROM's "ping"; not used during installation
  • bootps (67/udp)
    • Privides BOOTP response, gives out an IP and points to TFTP sever
  • tftp (69/udp)
    • Allows the transfer of initial installer tools
  • shell (514/tcp)
    • Used by Inst to transfer the majority of data

Download this docker image and check: 

docker pull nickpgsmith/irix-install
docker images

Create a bootptab file in /home/user/irix: 

sgi:ha=0800690b9e1f:sa=10.0.0.1:ds=10.0.0.1:rp=/data

where ha is the Ethernet address of the SGI, sa is the IP of the TFTP server, ds is the IP of the DNS server.

Start Docker image (as root): 

docker run --name irix --network host --add-host sgi:10.0.0.2 --volume /home/user/irix:/data:ro,Z -it nickpgsmith/irix-install

Ensure firewall is not blocking: 

firewall-cmd --add-port="7/udp"
firewall-cmd --add-port="67/udp"
firewall-cmd --add-port="69/udp"
firewall-cmd --add-port="514/tcp"

or: 

systemctl stop firewalld

Can boot standalone shell with any of: 

boot -f bootp()lin-docker:/inst/dist/sa(sash64)
boot -f bootp()lin-docker:inst/dist/sa(sash64)
bootp():/inst/dist/sa(sash64)
bootp():inst/dist/sa(sash64)

NOTE: It seems like replacing the hostname ("lin-docker") with the IP does not work.

Disk Labelling

The disk needs to have an SGI label and partition structure. Invoke disk partitioner with either: 

boot -f bootp():inst/stand/fx.64 --x
bootp():inst/stand/fx.64 -x

Accept defaults for disk: dksc(0,1,0) 

fx: "device-name" = (dksc)
fx: ctlr# = (0)
fx: drive# = (1)
...opening dksc(0,1,0)

To show current partitions:

  • /label/show/partitions

Partition root drive (for OS installation) with defaults:

  • /label/create/all

By default, 128 MB of swap is allocated as partition 1. To change, use:

  • /repartition/resize

A non-root disk can be partitioned:

  • /repartition/optiondrive

Erase disk and check surface for bad blocks (slow):

  • /exercise/sequential
  • modifier = “wr-c”, enter start and number of blocks

Exit:

  • /exit

Installation

(Graphical):

  • Select "Install System Software"
  • Select "Remote Directory"
    • For "remote host" enter the hostname of the install server (lin-docker)
    • For "remote directory" enter the sub-directory from the /home/user/irix base where the stand-alone shell (sa) is located (inst/dist)

This is equivalent to the command: 

xio(0)pci(15)multi(0)network(0)bootp()lin-docker:inst/dist/sa(sash64)

(From PROM Command Prompt): 

bootp():inst/dist/miniroot/unix.IP30

Installer will present:

  • If there is a newly partitioned disk, a report of no realroot will be seen:
    • Confirm create new file system on /dev/dsk/realroot
  • Choose 4096 bytes blocksize for disks ~> 4 GB
  • Enter hostname, IP, Netmask
  • Inst 4.1 Main Menu (Inst> prompt)
    • For nonclean disks: 13/11/y/yes
    • Change hostname and IP: 13/12 and 13/13

NOTE: >Inst uses rsh (not TFTP) so subsequent paths are relative to / not /data

  • Open Source: 2
  • Choose location (/data is the mount point within docker)
    • lin-docker:/data/inst/dist
      • Confirm network address
      • Choose feature stream (2)
  • Continue to add additional disks from RSH root:
    • lin-docker:/data/overlays2/dist
    • lin-docker:/data/overlays3/dist
    • lin-docker:/data/found1/dist
    • lin-docker:/data/found2/dist
    • lin-docker:/data/nfs/dist
    • lin-docker:/data/apps/dist
    • lin-docker:/data/capps/dist
    • lin-docker:/data/apps/dev_libs
    • lin-docker:/data/capps/dev_found
  • Return to >Inst (11)
