I just assembled my new Unraid build which is as follows:

case: fractal node 304

mobo: MSI MPG B560I

CPU: Intel Core i5-10600K

Memory: https://www.amazon.com/gp/product/B08HLYSHJC/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

PSU: https://www.newegg.com/super-flower-leadex-iii-sf-550f14hg-550w/p/1HU-024C-00008

CPU Cooler: Noctua NH-U14S, Premium CPU Cooler with NF-A15 140mm Fan

 

I just got everything put together and put in my 3 HDDs and my unraid USB drive.  When I tun on the system, it boots into the BIOS.  It seems to detect everything correctly - it shows the correct CPU and memory.  It see the hard drives and the USB stick.  I set the boot order to boot from the USB stick.  but after I reboot, it just keeps booting into the bios.

 

If I unplug the power cord from the PSU, wait a moment and then plug it back in and boot back up it usually spins up for a second and then shuts down - then spins back up and says "All settings were reset to default values"

Press F1 to Run SETUP

Press F2 to Continue

and all the bios setting I have made have been reset to default.

 

what the heck could be wrong?   I have not built a pc for several years so its possible I may have screwed something up

 

any advice would be greatly appreciated!

Shouldn't be the problem with a new mobo, but you might check the CMOS battery.

Thanks.  I didn’t see a battery on this motherboard.  I know they used to have the coin battery on them but I didn’t see anything like that here. 🤷‍♂️ 

Also it does appear that the date and time are not correct In the bios. 
 

I did double check the cmos jumper and there’s nothing on it. 

You have to set the date and time manually in BIOS.

There's a laptop type CMOS battery on the MOBO (visible as attached to the red/black wire in the left lower corner)

 

Thanks lolight. After removing the CPU cooler I was able to get a closer look and I see the battery. Is there a place where I can get an inexpensive replacement to try?

Also, I think the really weird part for me

is that after I first connect the power and turn it on, everything spins up for a few seconds… but turn shuts down for a few seconds and powers back up with the cmos settings reset. 
 

and it only does this the first time after reconnecting power.

First try re-connecting the battery to the MOBO -  the connector might not be fully inserted.

You can get a cheap laptop CMOS replacement battery with a matching connector (2 or 3-pin) on ebay.

The connector is very small and tricky to disconnect. Make sure not to damage the socket it's attached to.

 

If that doesn't solve the problem I'm afraid you'd have to RMA your MOBO for a replacement.

That was a good call!  Once I took everything back out and got a closer look, the connector for the cmos batter was actually loose.  I reseated it and reassembled everything and now it’s holding the bios settings!

 

now the next problem I am having is that I can’t seem to get it to boot from the flash drive. It sees it in the bios and I have set it as the primary boot device,  but it just keeps booting into the bios. 
 

I have found a few threads for other motherboards which said they had to switch from UEFI to CSM to get it to boot from the flash drive, but apparently CSM can’t be used without a discrete graphics card. 
 

I tried to switch it to CSM and when I reboot it displays an error message and reverts back to UEFI. 

 

Any ideas on how I can get it to boot from the flash drive?

You also have to rename a folder on flash to make the switch

 

EFI for UEFI

EFI- for nonUEFI

Folder needs to be named EFI to allow UEFI boot, but CSM boot works either way.

Perfect - that did the trick - thank you!!

 

so now one other issue I noticed.   It booted right up and everything was normal, but when I rebooted, it would not boot back into unraid.   It got through the POST, and then just went to a black screen.  The web up was not available and my router did not show the device as online.

 

I powered down, removed the flash drive, re-inserted it and then powered back up and then unraid booted.

 

This seems to be happening every time I reboot.

 

any ideas?

Try another port, USB2 recommended

Thanks trurl - I had the same thought and I have actually tried every available port with the same result, including the two USB2 ports.   It didn't seem to change anything.

 

One thing i did notice though is that after a reboot, if I unplug the usb drive and plug it back into the same port - it still hangs after I boot back up. It will only boot if I plug it back into a different port.

 

 

i did some googling and found a thread on reddit where they described a very similar problem but they didn't seem to have a solution listed.  I'm glad the system is working in general - but I do wish I could get past this last issue.

 

 

 

 

I used to have a PC years ago where the USB port wouldn't reset on reboot. I had to power off.

Check if the board is on the latest BIOS.

Yes I have updated the bios to the latest available version. 
 

 

I found the solution for this in another thread (see below).  The solution was to disable the fast boot option in the bios.   Now everything works perfectly!
