The particular issues may vary, but in general you should check ACPI tables first. When debugging sleep issues you may want to (temporarily) disable Power Nap and automatic power off, which appear to sometimes cause wake to black screen or bootloop issues on older platforms.
While it may not be required, sometimes you have to disable Thunderbolt support, Intel SGX, and Intel Platform Trust in BIOS if present. VT-x, Hyper Threading, Execute Disable Bit enabled in BIOS if present. See VerifyMsrE2 section for more details.ĬSM disabled in BIOS if present (you may need to flash GOP ROM on NVIDIA 6xx/AMD 2xx or older, using GopUpdate or AMD UEFI GOP MAKER could simplify things).ĮHCI/XHCI Hand-off enabled in BIOS only if boot stalls unless USB devices are disconnected. No slide boot argument present in NVRAM or anywhere else (it is not necessary unless you cannot boot at all or see No slide values are usable! Use custom slide! message from AptioMemoryFix).ĬFG Lock (MSR 0圎2 write protection) disabled in BIOS if present (consider patching it otherwise if you have enough skills). VT-d disabled in BIOS if present (you could also drop ACPI DMAR table with a bootloader). While no other motherboards with the same issue are known, consider this option to be first to check if you have erratic boot failures. WARNING: On some motherboards (notably ASUS WS-X299-PRO) this option causes adverse effects, and must be disabled. Most up-to-date UEFI BIOS firmware (check your motherboard vendor website).įast Boot and Hardware Fast Boot disabled in BIOS if present.Ībove 4G Decoding or similar enabled in BIOS if present.

Fixes mouse movement via EFI_SIMPLE_POINTER_PROTOCOLįork of the original OsxAptioFix2 driver with a cleaner (yet still terrible) codebase and improved stability and functionality.Sends pressed keys to APPLE_KEY_MAP_DATABASE_PROTOCOL.Generally modified UsbKbDxe works better on APTIO V, but for Z77, Z87, and similar AptioInputFix may be the only solution.
Reference driver to shim AMI APTIO proprietary mouse & keyboard protocols for File Vault 2 GUI input support. Due to the lack of time, this codebase may contain partially understood reverse-engineering samples, almost no documentation, hacks, and absolute ignorance of EDK2 codestyle. WARNING: The code in this repository should be considered to be a proof of concept draft quality, and is only intended to be used as a software implementation guide.
