I just got 2 Iris Indigo Chassis. One with PSU and Main 3K board, and Other with PSU and Basic Video Board....I was able to repair one of the PSU and did the battery mode on the logic board of CR2032....

The system Start up, make sound but no video so far....I dont have HD or Keyboard and mice.....any one to verify if the unit at least is operational before I spend more money!

With no keyboard, I think it will look for console input on the first serial port... Probably a serial "null-modem" cable that works on an Indigo2 or Indy should work on the Indigo.

So the Iris Indio use DIN-8, so I need to create a adapter to DB9....any information on the terminal settings....

Any other way!

Excellent tutorial here:

just remember that you need to pull the graphics card to get serial console.

No, it's enough to disconnect keyboard & mouse. Which he didn't have in the first place.

If you do that you may get 'gfx=dead' in your PROM environment. That doesn't mean the graphics board is dead, but that the graphics console doesn't work.

Well, at least I have an Indigo where just this doesn't suffice. If I leave the graphics card in, it will output "something" on the serial port, but won't offer access to the PROM. That is the general behavior that I remember from several Indigos back in the day.

I was curious so I gave it a try. This is an R3000 Indigo Elan. I normally use it with a keyboard, mouse & screen attached.



The graphics board is still in the system...

If the 'console' is set to 'd', then you'll get the "Running Power-On Diagnostics" and "Press ESC to enter PROM" messages as well.

You just have a dim-8 to db9 RS-232 cable or you have to make it!

I have a couple of these. it's not hard to make them if you can find the parts (mostly the mini-DIN8 connector) and can do basic soldering. The pinout of the mini-DIN8 port on the system is documented in man(7) serial:

Code:

The DIN-8 serial port connectors on the Indigo, Indy, Indigo2, Challenge
S, Challenge M, Power Challenge M, and the MENET 4-Enet, 6-serial board
(XT-FE-4TX-6A) have the following pin assignments.
    ---------
    / 8 7  6 \
   (  5 4  3  )
    \  2  1  /
    ---------
    _________________________________________
      Pin  | Name    | Description
    _______|_________|_______________________
      1    | DTR     | Data Terminal Ready
      2    | CTS     | Clear To Send
      3    | TD      | Transmit Data
      4    | SG      | Signal Ground
      5    | RD      | Receive Data
      6    | RTS     | Request To Send
      7    | DCD     | Data Carrier Detect
      8    | SG      | Signal Ground

Technically even a simple 3-wire NULL modem cable should work at 9600 baud, but on the older 4D systems you'll miss some of the very early diagnostic UART output if you don't have hardware handshaking lines.
