I've sadly fried my CPU somehow and I know that bplan no longer make new modules so should I throw my Peg2 that I bought three days ago (used system) on the dump? The cause of the fried CPU was because I did turn down the speed of the chassis fan. After that the computer hang I shout it off and put the fan back on full speed but after I put the power on nothing happend.
Are there any company that can reapair CPU modules?

i doubt pegasos is dependent of a chassis fan to operate,
cpu module have its own heatsink and (crappy)fan.

Does the cpu fan still work ?

yes it does.

Did you try another power supply? Those can also go at any time, and then nothing will happen when you push the button. For tha matter, are all the wires still correctly and firmly inserted in the motherboard's pins? Don't give up yet!

Tronman!!!

I'm mously sure that I fried the chip bacause I actualy used the system when it happend. The system hang and after a reboot it hang again so I put the fan back on full speed but after that It didnt boot at all.

To avoid misunderstandings, did you turn down the PSU-fan, or an extra fan for the chassis ?

I know there are tight cases, and that there is unpotimal airflow, but if a Peg survises with just CPU and PSU fans in an ODW it should do so in any other case.

Indeed, try everything you might think of before throwing that CPU module to the bin. It can be a faulty power supply, like mentioned here.
As a side note, I (wishfully) thought that it wasn't so easy to burn a modern component like a PPC CPU. Doesn't it have any kind of thermal or current protection? Should it had been provided by the card itself? I really thought that modern components had shutdown systems when certain conditions are met.

You reduced the speed of the fan?

Were you monitoring the temperature of the CPU?

Quote:

CPU over temperature shutdown would be an active thing - something in software would have to be aware of it. I strongly suspect MorphOS has no task that monitors CPU temperature (at least, there's nothing in MOSSYS:C/ that does it).

Sorry to hear about this for the thread starter

1. There is no temp sensor in built in MOS but IIRC Amigazeux has a cpu temp tool..

2. There is no hw shutdown on the cpu card - if the fan dies the cpu will just get hotter until it fries (and it doesnt take long at all)

The CPU fries in the twinkling of an eye, did happend to me especially when you use dnetc client.

Yep
I had a cpu catch fire when the fan failed.. not pretty. I now have my peg in a case with a CPU Temp sensor with lcd readout so I know if the cpu starts to go crazy hot the fan failed. I have also replaced the bplan heatsink/fan with a nice copper Vantec cooler. Highly recommended to do this.

Dear AmigaFF,

just send us an email. Normally every CPU card can be repaired. We are not longer producing CPU cards, but repair or replacments if needed can be done.

Regards
Thomas

bplan

Great news and nice to see you post here!

@bplan

That's great to hear, and a much needed statement for the rest of us Pegasos customers as well!

Quote:

Yeah, as I recall there's an 8-bit temperature register. I don't think it's implemented in all PPC cores though. It's been some 7 years since I read the PDFs on PowerPC assembly and my head is a little rusty.

For certain, the register wouldn't be accessible without software, so a hardware-based watchdog for temperature wouldn't be possible.

The temperature sensor in MPC7447 is broken.
It exists but it doesn't work. Otherwise we would
all use it with Linux.

I know that bPlan still repairs broken Pegasos machines. Ask them.

And perhaps, just for a matter of news, Here in Italy ACube, announced they will repair any AmigaONE CPU broken Modules.

Yes I know they are the manufacturers of Samantha motherboard but sure it is interesting that they announced this repair service for the Amiga community.

I could ask if they have the intention to made such a service for Pegasos users too.
Maybe this could be a good point to start hardware co-operation between AmigaONE side, and Pegasos side.

But certainly at ACube they must ask permission to bPlan to made repairs.

Sure, for me who I am italian, the fact to have a Pegasos repair center here in Italy this will be sure a bonus...

It is just a matter of co-operation between two firms in a small market...

And I hope both firms could agree to have a peaceful and friendly communication.

What do you all think about it?

May I ask to ACube if they are interested in keeping a repair center for Pegasos too?

- IMPORTANT UPDATE -

I contacted ACube representatives on about Pegasos repairs.

They think it is possible to realize Pegasos repairs also, together with AmigaOnes in their existing AmigaONE repairs facility! (Wooohooo!)

They have no problems in supporting even repairs for Pegasos machines too, as long as bPlan/Genesi will be so kind to consider ACube as a professional repair center here in Italy and will include it in the number of their partners.

They are always enthusiast if they could start any professional partnership with bPlan/Genesi.

This fact could became a starting point and an opportunity to realize in the future other agreements with bPlan/Genesi regarding other projects.

For example I found interesting the fact that ACube it is producing Expansion Cards to upgrade AmigaONE old processors.
Perhaps they could start to produce Expansion Cards to be mounted on existing Pegasos (But this is only a wishful thinking of mine who own a Pegasos II G3 600 MHz and I never reached in time enough money to afford G4 Expansion card).

Facts remains that at ACube are waiting any positive or negative comment from bPlan/Genesi here, on this sub-thread I started about these repairs...

(Sounds good!)

...They prefer to wait because even if they are interested in supporting Pegasos market, and they desire to take direct contacts to start any kind of agreement (or receive explicit permission to do repairs) just because (due to actual situation of Amiga market splitted in two parties) they don't want to force the situation in making any kind of move which could be considered offensive from side of bPlan/Genesi.

So bPlan/Genesi, now it is up to you.
If you are interested, then contact ACube. They are awaiting for any serious agreement proposal.

@Raf

What do Acube think of you being their new PR guy?

I just started this sub-thread on about off-sourcing Pegasos repairs due to a matter of curiosity when I spotted this thread on Pegasos repairs...

1) I contacted A-Cube for a matter of curiosity when I congratulated with them on about their agreement with Hyperion...

And now here I am just reporting what they said to me, and mainly what I sensed from the conversation...

(the fact they are looking for a contact but don't want to offend Genesi by overcoming situation)


2) And I reported also some personal considerations about the possible future...

(repairs -> production of new CPU modules)

I hope I was clear...

3) Consider me a sort of amabssador between two camps rather than a Public Relations Man just from only one side...
