Re: Snap 4100 BIOS dump, unlocking 137 limit
4.0.860 (patch) adds MS AD support ONLY. If you are moving up from v3 you need to install the full version 4.0.830 first.
LB48bit IS NOT SUPPORTED on the 4100. It has a hardware problem with the promise controllers. There is no way around this, believe me we have tried. v4 requires slighly more overhead than v3. It is recomended that you have a minimum of 128 meg for better performance.

Re: Snap 4100 BIOS dump, unlocking 137 limit
Sounds interesting, BUT
What are you going to do to correct the bug in the promise controllers????? The original reason they were locked out. Now I agree that some of the newer models should have an updated chip without the problem. And Snap may have decided to keep it messed up to sell the newer models. Another thing to consider. If you have a HD failure, and need to replace a drive. You may/will need to have a spare pre formatted drive from a 2200.

Re: Snap 4100 BIOS dump, unlocking 137 limit
The Promise controllers were not locked out, Snap simply didn't want to spend the extra man hours needed to upgrade the driver. The reason why it works in the 4000 is because those use the native Intel chipset ide controllers although the throughput is slower. The drivers for lba48 on promise chips came late and snapos is not exactly using a bleeding edge bsd kernel. As soon as I get a spare 4100, I'm going to see if I can get FreeNas onto the flash chip. Meanwhile, I can probe the 40 pin header to see what it is. I'm thinking that it connects to the flash drive from another computer and looks like a drive to it so a direct image write would make it easy for the mfrs to get it up and running since it is headless and has no terminal com port either.

Re: Snap 4100 BIOS dump, unlocking 137 limit
If you got FREENAS on it, it would open up a whole new world

Re: Snap 4100 BIOS dump, unlocking 137 limit
I have a programmer with the TSOP socket and flashram, if I can be of any help.
Man it would be nice to see FreeNAS, Or any other kernel in these units. FreeNas is about 1-2 betas off to getting the auto mounts working on reboot.

Re: Snap 4100 BIOS dump, unlocking 137 limit
Yeah, anything would really do
Especially if we can then port it to other Snap OS Units As long as it is able to be configured externally, and then moved over, or be able to have a IP assigned by DHCP after copy, it doesn't really matter!

Re: Snap 4100 BIOS dump, unlocking 137 limit
I downloaded it again and didn't have any problem unziping it with winrar.

Re: Snap 4100 BIOS dump, unlocking 137 limit
The currently dumped code is just the PIC code
Not the code from the flash chip We are still waiting for someone to dump it for us! Hence the Post Quote:

Re: Snap 4100 BIOS dump, unlocking 137 limit
I thought he mentioned that the flashram was soldered in.

It is soldered in...makes things a little tougher.

Re: Snap 4100 BIOS dump, unlocking 137 limit
The Header on the circuit board of my 2000 there is what looks like and IDE header but is labeled ISP, usually refered to as In System Programing.
Right next to that header is a blank spot that looks like it might be used as a socket for a DOC, Disckonchip. |

Re: Snap 4100 BIOS dump, unlocking 137 limit
The v1 board does not have the ISP header. But it has space for a SCSI controller and header. The ISP header is on the 1100 board though.

Re: Snap 4100 BIOS dump, unlocking 137 limit
My 4100 has the IDE header. It shows pin 1 and pin 2 and doesn't say ISP anywhere near it. It does look as though some of the tracings lead from the flash to this header. I tried to use a USB/IDE adapter but my laptop never recognized anything. I did the hard drive bit too, but like an earlier post stated, the system just wouldn't boot.
I do wonder if an IDE Flash Module would work. http://ec.transcendusa.com/product/p...=59&indexnum=9 |

Re: Snap 4100 BIOS dump, unlocking 137 limit
Anyone want to try this to dump the flash chip?
http://www.uchobby.com/index.php/200...d-flash-chips/ According to the article, all you'd need is a smartmedia reader, not a fancy chip programmer. |

Re: Snap 4100 BIOS dump, unlocking 137 limit
Are people still needing this flash dumped? There is only one chip to work with on this board.

Re: Snap 4100 BIOS dump, unlocking 137 limit
NO, It's a dead OS, so we have started moving to Guardian OS units.
I had done some research and found out that there is not enough room to enable LBA48bit. The only way it could work would to convert it to a std boot loader. Too much work, and I know of no one who has the knowledge to reverse engineer the OS.

Re: Snap 4100 BIOS dump, unlocking 137 limit
Too bad GuardianOS won't run on these 4100 units. Any ideas on the size of the flash?
I have a 160Gb 4100 that I plan on upgrading with some new 160Gb drives. I just wish it would see past the 137Gb limit, but oh well.....it's still a heck of an upgrade. Once I do this, I can use S2S to fully mirror my 480GB 4100 to this one. |

Re: Snap 4100 BIOS dump, unlocking 137 limit
I believe they are 4meg units.
