Does anybody find the place where ID chip in Fuel is located ?
Is it the same chip like on Octane or new one ?

I have never owned a Fuel but it is large Dallas 1742W . The same as what is in the Origin 300s from what I can tell from this wiki topic...
Something that large would be difficult to not to spot on a board.

Thanks a lot !
I've also found that it's not replaceable with Octane

I thought I remembered seeing that Fuel used a small encrypted EEPROM for the serial number.

This is not gospel, it's been quite a while since i had to mess with it, but both of you are right. There's an atmel system i.d. chip over towards the left end of the pci sockets AND apparently the Dallas chip remembers some settings, so when you change i.d.'s it's best to change both, if possible. At least, that was my experience.

Well, now I have a real mess...
So :
1. there's two chips -Atmel and Dallas
2. which of them carries sys ID : Atmel or Dallas ? Both ??? The same ID ???
3. Which of them can be reprogrammed and how?

Search for some posts by pinball cf the Atmel. I believe the thread was about fixing the environment sensor chip, which is nearby.

2. which of them carries sys ID : Atmel or Dallas ? Both ??? The same ID ???

I replaced the mainboard years ago and had to move both. Not sure what that means or if it was a fluke or a screwup on my part, but something to be aware of.

3. Which of them can be reprogrammed and how?

The Atmel cannot be reprogrammed. Don't know about the Dallas. Are you trying to maintain an id for some licensed software ? You can't move both chips over just to be safe ?

It looks like he's trying to move over from an Octane or other NIC system.

Wasn't there a piece of software around that did a non-permanent change of the serial number after it was loaded into IRIX?

FWIW, I believe the Dallas can be reprogrammed. The "fix" for the serial number mismatch issue is to put in a blank Dallas chip in the r-brick and its gets programmed from the L2. But I suspect it might be compressed or encrypted.

I have a spare o3k r-brick programmed with security enforced Dallas chip taped inside the case of the r-brick if its needed.

THAT would be difficult.

Yes. Sysid was the name. But it's not persistent .... although not a problem I guess, just load it every time you boot ....

Nobody mentioned the L1 'eeprom Fuel write default' command yet:

Code: Select all


   001c01-L1>help eeprom
   

   eeprom
   

   show brick eeprom data.
   

   eeprom <exp> <exp> <exp>
   

   show brick eeprom data at <eeprom> <offset> <length>.
   

   eeprom Fuel write default
   

   write standard Fuel EEPROM data to MAC EEPROM

The Atmel chip is write-once so you can't change ID data stored there. But the day your Dallas chip runs out of battery you may be able to initialize a fresh Dallas using the above command. It will probably use default data and the serial number stored in the Atmel. Fortunately, I didn't need to do this yet so this is all speculation.

If you want to change the MAC address of the system to migrate licensed software, you should google the 'squirrel' method.

Now this is a deep dark secret, so everybody keep it quiet

It turns out that when reset, the WD33C93 defaults to a SCSI ID of 0, and it was simpler to leave it that way... -- Dave Olson, in comp.sys.sgi

I figure you can identify the Dallas chip all by yourselves
