Hi! I've updated the firmware of my X670E Taichi to BIOS 4.20 (AGESA 1.3.0.1). Everything is running well. No issues. However, there are 2 bugs: 1. I tried to save a BIOS profile on a USB flash drive, but I couldn't. The UEFI menu told me that it did save it, however I couldn't find it on the USB drive, after restart. I've tried multiple times , and inserted the USB drive in both USB 3.1 & 2.0 ports, without luck. The drive is formatted as FAT32. 2. Sometimes, the mouse isn't working while in the UEFI menu. It is visible on the screen, but it's unresponsive. (This bug was present in previous BIOS versions too). |

If you could additionally open a support ticket and report it there with a link to this thread that would be great. http://tw.asrock.com/events/tsd.asp" rel="nofollow - http://tw.asrock.com/events/tsd.asp If anyone else has any bugs to report on the X670E Taichi feel free to drop them here too. -------------

<Update> Hello! Both of my issues have been solved: 1. I've used a different USB flash drive, which works. I was able to save the BIOS profile on it. (Though I have no idea why the first one didn't. That first one was used to update the firmware from. It was FAT32). 2. I've removed the mouse that's not working in UEFI (Dell Premier MS900) and removed its dongle too. I've connected the Dell mouse that is combo with the keyboard (Dell Premier KM7321W) and that one works in the UEFI menu. Maybe, having 2 Dell dongles confuses the UEFI? (I've wrote about these things to the ASRock TSD too). |
