sleo Posted January 6, 2023 Author Share Posted January 6, 2023 Thanks. Dw1560 runs parallel on Windows 11. Dw1830 didn't run because there are no drivers for it under Win 11. I'll try installing a fresh copy of Monterey in that case and let you know. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted January 7, 2023 Administrators Share Posted January 7, 2023 Re: BIOS, I think you're very confused and no OC package can contain a BIOS update. If your BIOS version shows A09, that's what you got. You can only update your BIOS through the DOS/Windows .exe published by Dell, i.e. only from Windows or through a DOS-based USB key for instance. Rest assured OpenCore does not touch BIOS or BIOS settings in any way. Link to comment Share on other sites More sharing options...
sleo Posted January 8, 2023 Author Share Posted January 8, 2023 Hi, I found the cause... My DW1560 stopped working on Windows 11, so I went back to a standard Intel card, but that didn't work either! It is probably a bridge on the motherboard, as one of the service guys informed me in a conversation on the subject, suggesting that I should switch to a USB Wi-fi card. This is probably what I will do too, repairing the bridge or replacing the motherboard is much more costly in this case. Of the non-antenna options I'm thinking Archer T3U + driver from Chris1111. Unless you have a recommendation for something better? PS Thanks for the lesson on BIOS and OC. Indeed, I am unfamiliar with the subject. Link to comment Share on other sites More sharing options...
