Hardware projects / Re: Z800 version 003 extracted BIOS image
« Last post by Animajosser on May 06, 2018, 10:30:35 am »
Hello, I am new to this forum and I have just used the bios image Mr. Brown uploaded and It seems to work. A more complete description of my problem is posted here: https://forums.anandtech.com/threads/custom-dual-xeon-build-restarting-needed-a-couple-of-times-to-finally-start-up.2543896/#post-39394527 . I bought 2 Xeon X5650 cpu's a while ago and a Z800 rev. 002 to use them in, as described on Mr. Browns blog. I found out that starting up didn't go as smoothly and after a long time I read on this forum and the comments that it had to do with the software on the bios chip. So I bought a CH341A bios programmer and five SST 25VF016B IC's on Aliexpress and flashed the new bios chip with the software posted in this thread. I used a tool from this page: https://tosiek.pl/ch341-eeprom-and-spi-flash-programmer/ and I installed the drivers with Snappy Driver Installer. Something I noted was that the software says wrongfully how to place the chip in the programmer. The notch of the chip needs to be turned 180 degrees, otherwise it won't work in this case. To conclude, I unsoldered the old bios chip as insurance and soldered in the new one in and it seems to work, as it hasn't done anything weird in 5-10 boot ups. It needs more testing of course and I'm rendering a difficult 3D-scene right now to stress test it (as I don't want the new bios to cause instability or something). This is no hardware mod, as it is wrongfully called, but a software mod. I had to replace the bios, because it was difficult to flash it with the motherboard, but the only thing I changed is some software on the bios chip.

I don't think an Internet connection should be a deciding factor these days, for the most part anyway.
I totally agree. I do see that some people object to 'cloud' based systems on principle but I'm not one of them.

I use Altium Circuit Maker as well, Andy. I don't think an Internet connection should be a deciding factor these days, for the most part anyway.

Hi, these days I use and recommend Altium Circuit Maker. It requires an Internet connection but if you can accept that then I think it's a very powerful system.

Hi Andy,

I would like to know what software you use to do your circuit designs.

Regards
John

Hope you find time for more projects soon! My free time also evaporated the last 6 months...

I'm here, just rather busy at the moment that's all. Thanks for the concern though!

Hey there, I'm not sure if this forum is still alive but it was very interesting to read some of the research done on displays and more stuff too. )
I am extremely interested in interfacing amoleds and hq cameras to Arduino devices and reaching out someone who could help/direct me.
I am a senior programmer (asm/C/C++/C#/Java/ASP etc) with electronic background and kinda going from high level to lower level of stuff like MCUs which I love ))
Anyways - cheers
