Huge Problem With Bios After Final Release

[e-senturk]

Hi, I've been using your clover for a while, it was working so far so good until the final catalina release. It triggered some bug on bios nvram part. My bios become unaccessable even after booted from instaler usb. I could be able to boot on windows or mac but when I tried to access bios just got blackscreen, then I tried to reflash bios via asus winflash tool but I couldn't because bios updates are installing into bios on asus devices sadly I got black screen again. I find a tool for ami bioses like ours, so I ve managed to fix the access bios but when I login catalina same thing happen again. Do you have any problem like that.

Anyone having this issue with that laptop just install emu-variable64.efi driver and rc scripts for this volume on clover. It brokes auto select on clover but its better than bios error.

I switched to opencore succesfully any after its nvram reset option I ve get rid of that problem. Also it might related with vsmc boot arg.

@valinor61 thanks for the update. Is this something you could submit as a PR to this repo to help us all? How can I do this on my machine?

[MohammadtaghiFarkhondekar]

I fixed it . Yesterday I will update project to v11 .

[e-senturk]

Without opencore or the tool I ve send it cant be fixed this error needs a nvram reset if anyone interested in I shared my opencore build based on that clover please add your system serial mlb rom and uuid value with opencore configurator in to the generic section. And add boot/opencore.efi to as a new boot option in bios if you cant access to the bios first use the file I send earlier (its on few post before) reflash your bios with all section. Expecially nvram part. OpenCoreGL553VD.zip
