bios

Hi guys, need a little help. I disabled VT-d, CSM and everything that could interrupt booting. I set my bios to see UEFI devices but it only sees my USB, and yes I copied EFI folder to EFI partition. The thing is, I don't have Windows installed, so I can't use EasyUFEI, is there something else I...

Asus TUF X299 Mark 2 I made the mistake of updating BIOS to v3006+ and my 10.13.6 failed to start. This mobo does NOT have USB flashback button and EZ FLASH would not allow earlier bios.cap files to be read/ downgraded. Getting a downgrade needed the following :- To create the DOS USB stick...

Finally my Kingston DC1000M (connected by an U.2 cable to an Asus WS-Sage X299) is booting and running! It was first of all shown in the OpenCore 0.6.6. Catalina Install. 1. The Install Guide of the Asus X299 informs us about, to have at least an CPU with 44 lanes to bei able to use the U.2...

Hello all, As mentioned in the title, my NUC does not show any video output (through Display Port) during boot. To use it I have to blindly guess the right combination of {arrow keys, enter key} that boots me into OS X El Capitan. When I guess the combination, after a few seconds, I finally get...

Hey! Please give some advice, cause i feel i am lost... I think i tried everything with Unibeast, Clover,and it's the same problem. I have a HP 250 G3 with Intel Celeron and i want to use Mac Os High Sierra (or lower) and i made a bootable USB following this guide...

Hi All, So my first venture over to Opencore has gone well however but it has thrown up a concern. If for any reason I get an unclean shutdown i.e. I'm at the picker list I think...crap I forgot to plug in that USB drive and push the reset button (no shutdown or restart option at the pick...

SOLUTION (using bcfg tool in OpenShell for some reason was not adding the entry. The following fixed the issue, but it may have just been the final step which was needed): Reflashed the BIOS then reconfigured to the same settings as stated below. Reset NVRAM via USB OpenCore (same as attached...

Hello Guys, I would like to ask, can the installation destroy the BIOS or damage EFI? In history I installed 5 computers (with Clover). From Sierra to Mojave. Every time without big troubles. In one case, an error occurred during the installation (probably due to incorrect EFI configuration...

Hi, i have been stuck with this problem for 6 hours now, and can't fix it still. I have looked on all websites and they all say i need to set XHCI Handoff to Enabled, however that doesn't exist in my asos BIOS. Anyone had this problem and solved it?

After a series of disasters with a Catalina upgrade, I'm now nearly back to a stable system with Mojave again. But every time I shut down my computer, on restart it won't boot past the 'Gigabyte' flash screen. I can't boot into BIOS and holding down the 'del' or 'F12' keys does nothing. The only...

Hi! I put a password on my Probook 4540s Bios when I bought it (that was a childish move) and now I forgot it because it was a long time ago. I contact HP support and they surprise me they don't reset the Bios password anymore the only option is to replace the board. Here is my chat history...

I installed macOS Catalina last Tuesday, a 100% vanilla installation, so the system is very stable, didn't have any problem so far, except for the clock, that is not matching my BIOS clock. MacOS will always be +4 hours compared to the BIOS, and when I boot to Windows, it uses the BIOS clock, so...

I am able to get the apple screen and the initial progress bar. When that first progress bar completes the screen just goes black and nothing else happens. I've searched the forums and can't seem to find a viable solution here. I followed the install guide as close as I could. When I got to the...
