1  Alternate cryptocurrencies / Mining (Altcoins) / Re: Need help! Onda D1800 BTC. Can’t get BIOS to display! on: January 09, 2018, 07:31:56 AM
I just set one up today  I made a usb stick with smos

I connected 3 molex
3 sata
a 24 pin
a four pin for cpu
I am using a 16gb usb 3.0 stick
and for now 2 1080 ti's
 
pretty much flawless and you don't need to

access bios it was set to boot with a usb stick and fire the board up

flashing bios was not the way to go.

or maybe you got a dude.

this board is really easy to do a 3 card well spaced 1080 ti build

What bios version do you have.

Don’t mean to sound like a noob but what is involved in setting up the usb stick. What exactly are you putting on it file wise.

So do you see anything when you give it power?  It sounds like you must, otherwise there's nothing you could do related to creating a boot drive.  If you're seeing the BIOS and can go into it, then the BIOS is fine - it would report a checksum failure if it gets corrupted.

If you are *NOT* seeing anything on the screen, when you power it up is it powering up and initializing your USB devices?  For instance, can you hit caps-lock on your keyboard and does the LED turn on and off on your keyboard?  If so, then it's probably something wrong with the monitor you're using, or the VGA port on the board.  The default CMOS setting on the D1800 is for it to use the internal graphics processor, so even if you plug something into the PCIe slot, it's not going to use it (default is for miners, not users).  The downside of this is that if there is something wrong with the graphics portion on the motherboard, you're SOL.

Flashing the BIOS is the same as any other device, format a FreeDOS floppy and run the batch file from the zip you download off of their site.

I use a ton of these boards, and they're a solid workhorse - never really had any problems with them yet...

Okay, so my usb devices do not initialize when I turn the power on. The cpu fan turns on and any gpu I put in a pci-e slot powers up, but the keyboard and mouse are unresponsive and unpowered. My monitor recognizes that the power has been turned on but reads "no signal". The monitor works fine with everything else. So, I am assuming that there is either something wrong with the board or the PSU. I am not sure what is powered by the 24 pin connector directly vs all the SATA/Molex power supplies.

Ok, so I’m pretty good with Linux development programming so I wouldn’t think this would throw me for a loop. I unboxed  the motherboard and was pleasantly surprised that is had a upgrade. An onboard vga slot that the seller said it had not. Ok, I went ahead and inserted the appropriate Ddr3l ram and connected the 24 pin and four pin cpu connectors from the EVGA psu. I plugged my monitor into the vga and then turned the PSU on. The cpu I could hear powering up. But nothing is being displayed on the scree? Ism’t The BIOS preloaded? I tried to insert a graphi card after powering down and using the hdmi output to see if I could get videos. Power up, the GPU fans spins but still no graphicss to mod the BIOS. Is there something wrong with the board, or just me  Grin. I tried all sorts of configurations going as far Ass creating a boot drive for win 10. How can I tell if the BIOS is intact, and if. Or how do I flash the bios on this model

did you plug power into the sata and molex slots?

they need power

I plugged all the SATA ones in but not the molex. The molix says “power out” so I didn’t want to short circuited anything

yeah that is wrong .  they need to be plugged in.

just make sure  they are in the right direction.


and this shows  the onda b250  with  3 sata and 3 molex plugged in

https://bitcointalk.org/index.php?topic=2138550.msg23791180#msg23791180

I am running them and I ordered 5 more.

Tell you what  when I get the next 5 on monday the 8th of Jan

I will show it to you.  or you could go to this thread

https://bitcointalk.org/index.php?topic=2138550.0


and look for it.

I killed my first 1800 board by putting the molex in upside down

https://bitcointalk.org/index.php?topic=2138550.msg22933260#msg22933260


and here is one down correctly

https://bitcointalk.org/index.php?topic=2138550.msg22938750#msg22938750


i had another one sent to me

Ok, so with everything plugged in it is still not working. I think it may have something to do with the 24 pin power. The USB ports aren’t providing power but the cpu fan is running, although fans for any gpu i plugg in run too. What is with the jumper pins next to the 24 pin power? Does this jumper need to be moved before operating board?

And what kind of memory is used? Recommended 1.35V
CMOS dumped?

I do have the correct memory
