Hi everyone. I got the Razer Blade 16 2024 Model with 4090 and i9-14th gen. Tryna turn off the Kernel DMA Protection but cannot find VT-d/DMA Protection option in BIOS. My BIOS version is 1.03. Win 11 pro 22h2. Wondering if such option can be found in unlocked BIOS and can be actually turned off.
My BIOS dump is here:
Thanks.
You could try to change the setting in NVRAM directly:
Thank you so much for ur reply!
I had a nice person named genius239 taught me this method too. Using setup_var SaSetup to change VT-d value. Unfortunately I get Unable to write data! error, which means even NVRAM write is protect by stupid Razer :((
He also taught me to extract NVRAM.txt to change value, but again, my nvram.txt doesnt contain VT-d option. Only stuff like BME DMA Mitigation shows up, which doesnt do anything.
