That was ages ago, and it was against me. I kept calm and didn't reply so the moron left. Now we are discussing at an higher level. People not understanding what the issue is for sure don't follow 18 pages of thread. Unless they are interested on learning something, sure.

I still think asking a person to read 18 pages is excessive.... even when it directly applies to them.  Specially when you consider how many of those pages have wrong or mis-information on them.  

 

 Disagree, look at the 'nay-sayer' gang, yourself, etc. Clearly there are some knowledge issues there.  Most of the poeple taking an oppositional position have no proof and have done nothing to help (aka. prove) their position.  People like RND and a few are putting in the time and effort to learn, test and report.  That OP stinks of the forum problem where people just like to post without being held accountable for their words/claims.  Again, if you don't like people correcting you or 'getting upset' about your OP then go edit it... that's on you, not them.

 

(and btw, those quotes were from a variety of people, and just from the first page or two.... just showing you that your OP bothered alot more people that you seem to recognize in your post)

Oh wait, I think I know what the PS3 mainboard eeprom is for....

 

It probably holds the bootstrap code, and some sort of safe-loader routine should a bad system software image develop.

 

It's common these days for a reserved and locked storage area to provide a way to recover by means of downloading firmware from a chip either by USB, CF, etc.

 

For Meade telescopes using the Autostar I, we hold <ENTER> and <Dn Arrow>, for Celestron scopes we hold <Info> and <Align>, for Synscan scopes we hold <8> and <9>.  Some systems automatically initiate a software update via the external memory card port like the Meade Autostar III.

 

 


I'm going to agree, it's most likely holding the 'recovery' options.  Considering that part of that is to rebuild corrupt HDDs it's completely logical to make the assumption that the code to recover a corrupt HDD is not on the HDD itself.  

 

I also agree that it probably contains the keys for encryption; not just necessarily the BD data.  As many of us know, if you change the main board out on your PS3 you cannot use your HDD.... you must erase and start over.  However, changing just the Bluray drive does not result in the data being inaccessible on your HDD.

I'm not sure on whether or not you could do that before?  I know that accessing bluray data in linux is not straight-forward.... it also wouldn't make much sense that it can read "one" bluray type but not another... I would suggest (not sure) that the indexing and all of the seek information for the disk, track, etc would be in the same area... sorta "boot-loader" style for the disk, like a table of contents.   ??

I agree, it doesn't make sense for some blurays to work and some to not.  I guess we can assume that the file format is slightly different for movies.  This might make them more susceptible to fail under the 3.xx updates.  I would bet my money on not-to-spec disc drives if it wasn't for this one weird symptom.  Lemon drives would easily fail from an update designed for a drive that is made to standard.

 



Proudly using 3.15 so as to retain my advertised feature of other-os.

Sony refuses to prove that your bluray drive did not "die" from a 3.xx update. Decide for yourself and ignore the ignorance.

Re: The FW upgrades DO NOT damage the BD drive!!

Just for those who don't know, firmware = go between the OS and the hardware. In this case, the OS tells the firmware to spin up the Blu-ray drive at certain speed. In many peoples case, the firmware does not work properly thus the XMB does not see the Blu-ray drive. Or the firmware dictates that the drive spins at X amount of speed, which is more than what the drive can handle, and it makes the drive die.

The line is blurred these days.

 

The firmware can be the operating system, the control logic for the hardware, and everything in-between, or part there-of.


It's nearly impossible to make the distinction between firmware and software.  When you try to define the two, you end up realizing that they are both the same.

 

My own classification is this...

 

Firmware - stored in non-volatile memory and executed from non-volatile memory (FLASH or PROM)

Software - stored in volatile memory and executed from volatile memory (RAM)

 

It doesn't explain every single case, but it's close enough.

 

But if you have to explain this to a neophyte, you're best off just calling it all software - keep it simple.

 

 

For the PS3 - I like the explanation:

The system software (those stupid updates Sony forces us to install at our own risk and peril) is the firmware.  Inside this firmware is the OS, drivers, middleware, and software (web browser, photo album, etc.).  Some of the system software is stored in flash memory, and some is stored on the hard drive (like the photo album, downloadable content).  The firmware can also contain other firmware destined for the various hardware - like the Blu-ray, NIC, hard disk controller, etc.
