ccvisabg Posted November 9, 2021 Share Posted November 9, 2021 Hello, i followed OC guide to install Vanilla install BigSur. Managed to install and boot into OS but my video card and sound not working. WIFI - not supported Audio - not working atm Video - no acceleration Tried to change couple of things but still my video shows 14MB of Vram memory Audio tried layouts 11, 12, 18, with no luck. Any idea is welcome at this point, tried to patch ram but there is no change maybe I'm doing something wrong. Here is brief summary of my hardware. Intel Core i7-5500U Computer Brand Name: Acer Aspire S7-393 Motherboard Model: Acer Aspire S7-393 Motherboard Chipset: Intel Broadwell-U PCH-LP (Premium) BIOS Manufacturer: Insyde Corp. Video Chipset: Intel HD Graphics 5500 Video Chipset Codename: Broadwell-U GT2 Video Memory: Unknown Audio - Realtek alc722 https://www.tonymacx86.com/attachments/screenshot-2021-11-08-at-8-43-05-png.533604/ Link to comment Share on other sites More sharing options...
Slice Posted November 9, 2021 Share Posted November 9, 2021 What guide did you use? Looks like wrong guide. Link to comment Share on other sites More sharing options...
ccvisabg Posted November 9, 2021 Author Share Posted November 9, 2021 (edited) Hi Slice, i used official OC guide (broadwell laptop), why you think that i used wrong guide? The problem is that i have video with no acceleration or if i patch it i got garbled screen (maybe related to csm) but bios is so restricted that i cannot if that is the problem. Attached is my "original" config. config.plist Edited November 10, 2021 by ccvisabg Link to comment Share on other sites More sharing options...
Allan Posted November 9, 2021 Share Posted November 9, 2021 Try to boot with this pre-made OC EFI folder for your Hardware: https://tinyurl.com/skaw2v94 Credits: @MaLd0n Link to comment Share on other sites More sharing options...
ccvisabg Posted November 10, 2021 Author Share Posted November 10, 2021 Thanks, same thing is happening when i put real device-id and platform. Computer BIOS is write protected so i guess i'm running out of options. 😕 Link to comment Share on other sites More sharing options...

ccvisabg Posted November 10, 2021 Author Share Posted November 10, 2021 Well, true but i cannot set any options for my video in BIOS. That is the breaker here. Link to comment Share on other sites More sharing options...

ccvisabg Posted November 11, 2021 Author Share Posted November 11, 2021 I don't have that option in BIOS unfortunately and BIOS is write protected. Link to comment Share on other sites More sharing options...

On my laptop #2 I resolved similar artefacts by reflashing BIOS to older version but this is not the option for you. Sorry. Link to comment Share on other sites More sharing options...
