ASUS P8Z68 Deluxe Gen 3 PAD issues even with MMTool #311
Description
System
- CPU : Core i7 3770
- Motherboard: ASUS P8Z68 Deluxe Gen 3
- BIOS Version: 3603 (Latest)
- RAM : 32GB
- GPU: Intel Arc A770 16GB
- CSM is turned off. Make sure to confirm this in the BIOS and not with GPU-Z or similar since it can be inaccurate
- 4G decoding is enabled. Make sure to confirm this in the BIOS and not with GPU-Z or similar since it can be inaccurate
- UEFIPatch is applied (see Using UEFIPatch for more information). On some motherboards DSDT Patching is also needed
- I have read Common issues (and fixes)
Description
I followed the guide, and when I got to the UEFIPatch step, I patched the BIOS using the command line. It applied five patches: three for PciHostBridge, one for PciBus, and one for Runtime.
Next, I extracted the patched modules from the patched BIOS file to replace them in MMTool, since UEFITool was giving me PAD errors. However, even with MMTool, I still encountered PAD errors.
So, I attempted to patch manually using a hex editor. I opened both the original and the patched BIOS side by side, but when I tried to search for the modified bytes introduced by UEFIPatch, the hex editor couldn't find any — not even in the original BIOS image.
As a result, I couldn't apply the patch manually either.
I also tried to skip the Runtime patch, same issue.
My best guess is that this is due to compression issues.
Is there any known workaround for this problem?
If so, could someone please provide the steps to follow?
Thank you.
