Hi Asrock, I have just upgraded my bios to version 3.10 and found a number of bugs in this bios version: 1. When power on it takes 20-30 seconds before the OS starts to boot. 2. In bios the feature to upgrade bios via network and network configuration has vanished. 3. no post if 2 GPU's are present and monitors are connected to GPU in pcie2. If monitors are connected to GPU in pcie4 it will post but GPU in pcie2 is disabled. If only one GPU is present it will post regardless whether the GPU is attached to either pcie. |

Hi! Got same problem.  Two graphics cards, only one post. And not the one in pcie2. Further research, card seems in d3 power state. Can't force it to d0 state. The other thing is, I cannot downgrade to previous version using instant flash with USB drive. File is found, show up on screen, but system says: invalid file. Any other way to fix it? |

Addition to my previous post. Computer seems to not shutdown completely too. CPU & GPU fan still running. Seems to take longer to post, I mean, after reboot, there's a longer delay before OS startup. And I checked the delay setting, still 1sec... |

I forgot to mention that about down-grading. I also tried going back to 1.80, which worked as expected, but was experiencing exact same thing as you. Another thing I also forgot to mention is that on the page where the list of found drives are displayed the detailed text is written in Chinese  . Maybe this version should have stayed inside the bios development department since it clearly wasn't properly tested before release to the public.

+1 to send that update to beta stage.... But... After many setting toggling, reboot, reseting bios, removing battery...  Got it working. It boot from primary GPU. Here's a list of setting that I changed : - SR-IOV Disabled - IOMMU Disabled - ACS ENABLED Disabled - SVM MODE Enabled - FAST BOOT Disabled - FULL SCREEN LOGO Disabled If you want to give a try, let me know your results. I'm interested. Some setting is for virtualization. Don't know if it applies to your setup, but I need them... Still on bios ver:3.10, I can't down-grading, but had listing is in English... PS: I may forget some setting, done a lot of change and reset..

Hi just for my knowledge, did you reset to deafult bios setting before the upgrade? thanks ------------- AMD Ryzen 7 2700X w/Wraith prism x470 Taichi bios 3.50 16gb HX432C16PB3K2/16 (hynix H5AN8G8NCJR-UHC) M.2 970 EVO, SATA SSD, 2 SATA HDD AMD Radeon RX 580 8G OC Linux Kernel 5.4 Manjaro Stable XFCE |

HI! Actualy, no! Not the first time I flash it to 3.10. But with all the instability and boot lookup trying to change setting to make it work; I've reflash it to 3.10 (since that the only one I can flash), after I reset the bios by removing the battery. |

| If you follow the instructions in [URL=http://forum.asrock.com/forum_posts.asp?TID=11230&title=b450-fatality-itx-bios-310-broken]this issue[/URL] by Am4_bored you can downgrade your bios to 1.80 which works flawlessly for me. Since I use Linux I had to make a Windows To Go usb stick which worked ;-) |

Simply download a windows 10 version from here: https://www.microsoft.com/en-gb/software-download/windows10ISO Pick the April 2018 download since the October 2018 download has a BSOD bug when booted from usb. For creating a windows to go usb simply use Rofus https://rufus.ie/ requires windows too so use virtualbox to create a VM using the iso downloaded from microsoft |

Hi thanks, I understood that you made a winpe usb. So you flashed the bios within a running VM under linux? Too much risky for me... ------------- AMD Ryzen 7 2700X w/Wraith prism x470 Taichi bios 3.50 16gb HX432C16PB3K2/16 (hynix H5AN8G8NCJR-UHC) M.2 970 EVO, SATA SSD, 2 SATA HDD AMD Radeon RX 580 8G OC Linux Kernel 5.4 Manjaro Stable XFCE |
