rthpjm Posted February 26, 2020 Share Posted February 26, 2020 (edited) Hi folks, This is weird! My build is based on the ASUS TUF Gaming X570-Plus (WiFi). I’m using OpenCore 0.5.5 as my boot loader. It’s 98% great with just a few things I’m still working on. Has anybody experienced these symptoms?... When I reboot I see the BIOS/UEFI splash screen that declares “press F2 or DEL to enter the BIOS settings”. If I press DEL as required the screen clears but I don’t see the BIOS settings screens. If I restart (ctrl alt del) go past the splash screen to OpenCore, choose to reset the NVRAM (causes a reboot), get to the splash screen, press DEL, and now it works. does anyone have any idea why the NVRAM setting appear to be stopping me accessing the BIOS settings?

rthpjm Posted February 27, 2020 Author Share Posted February 27, 2020 Solved - at least I think I found a work around... The BIOS has a setting for the splash screen size: auto, full screen, hidden I’ve set that value to full screen and it now seems to consistently enter BIOS settings when required. My guess is that the OpenCore control of the UEFI console (GOP) is introducing something that is incompatible with BIOS screen drawing. Probably the OpenCore screen resolution. It’s just a guess but it seems reasonable. Since the work around appears to have fixed my issue I won’t progress any further. I don’t think it’s a bug, just an incompatibility. I’ve posted here in case anyone else hits the same issue... Link to comment Share on other sites More sharing options...
ja7682 Posted August 25, 2020 Share Posted August 25, 2020 How were you able to set the value to full screen if you couldn't get to the BIOS settings? I'm having a similar issue where I press DEL when it tell me to, then the screen goes black. Link to comment Share on other sites More sharing options...
ja7682 Posted August 25, 2020 Share Posted August 25, 2020 I was eventually able to get to my BIOS by taking out the M.2 SSD and booting up. After I got into the BIOS, I shut down, reinstalled the M.2 SSD and was able to get to the BIOS again, this time with the SSD in. (Side note, I was able to cause the problem that put it in this bad state to begin with, and taking out the SSD fixed it again.) Link to comment Share on other sites More sharing options...
