Hi!

I accidentally corrupted my bios using Smokeless UMAF. Now the igpu won’t work unless I go into bios on a cold boot/restart, hit F10 to save and exit, then the igpu starts working.

Using CH341a FPT, dumped my current bios and attached to this topic.

Can someone make a clean bios or point me to the direction of how to make one?

If we can add the option to change igpu UMA buffer, that would be great!

Thanks!

The Asus file (EZ version) should be useful, just extract the UEFI image from the Aptio CAPSULE Header size: 800h (2048)
You may need to replace the 1rst pad volume as it contains your system data/win key lic.

Thanks! I did that today, fingers crossed, the laptop booted. But the problem persists. Still causing the iGPU to return code 43 in device manager. I believe the corruption might be in the padding. But I don’t know enough about bioses, evidently, to be certain it’s in the padding.

I’ve seen this issue with desktop boards when secure boot is not enabled. However, it’s enabled in my case, although, something about saving the bios on every boot makes it work.

I’ll play around with the non critical blocks unless there’s a better way to approach this.

I managed to fix the iGPU issue by patching the OROM VBIOS with UBU. I no longer need to go to BIOS to make sure it’s initialized.

Awful how Asus won’t fix this and the bios had been up for more than a year.

It’s been a great learning experience!

Thanks!
