I ask for help with DSDT Patching,
Motherboard: Asrock Fatal1ty Z170 Gaming K4,
CPU: CoffeeTime 0.99 Mod QTJ1,
GPU: Saphire 7900 XT.
Adding FFS module – ok
Enabling hidden 4G decoding – ok
UEFI Patching - ok (Remove <64GB BAR size limit (Skylake/Kaby Lake/Coffee Lake))
CSM-Disabled
Problems:
Above 4GB MMIO BIOS assignment - Enabled, causes a very long Windows boot time of 3-4 minutes.
GPU-Z says ReBar is Enabled, AMD Adrenalin says ReBar is not available.
In games, the FPS of 15 frames is catastrophically low, WINDOWS is "viscous".
I'm starting to do DSDT Patching, the problem is Decompiling
```
iASL Warning: There were 14 external control methods found during
disassembly, but only 0 were resolved (14 unresolved). Additional
ACPI tables may be required to properly disassemble the code. This
resulting disassembler output file may not compile because the
disassembler did not know how many arguments to assign to the
unresolved methods. Note: SSDTs can be dynamically loaded at
runtime and may or may not be available via the host OS.
To specify the tables needed to resolve external control method
references, the -e option can be used to specify the filenames.
Example iASL invocations:
iasl -e ssdt1.aml ssdt2.aml ssdt3.aml -d dsdt.aml
iasl -e dsdt.aml ssdt2.aml -d ssdt1.aml
iasl -e ssdt*.aml -d dsdt.aml
In addition, the -fe option can be used to specify a file containing
control method external declarations with the associated method
argument counts. Each line of the file must be of the form:
External (, MethodObj, )
Invocation:
iasl -fe refs.txt -d dsdt.aml
```
If ignored, I can't compile the file back without even making changes to the file. It is not compiled. Errors appear.
```

I can't fix it myself, I've tried recipes – there are even more mistakes.
My BIOS
[RebarMODBios.zip](https://github.com/xCuri0/ReBarUEFI/files/14384807/RebarMODBios.zip)
The original BIOS was modified in order
1) Coffee Time 0.99 + Opening hidden settings sections.
2) Resize BAR mod.
