I have installed MacOS and Windows on the following hardware:
AMD Ryzen 7 3700X MSI B450M Mortar Max Sapphire Radeon Pulse RX 5600 XT 6G Samsung 860 QVO, 1 TB SSD (PciRoot(0x0)/Pci(0x1,0x3)/Pci(0x0,0x1)/Sata(0x5,0xFFFF,0x0)) - MacOS on this disk Kingston A2000 SSD 1TB M.2 2280 NVMe (PciRoot(0x0)/Pci(0x1,0x1)/Pci(0x0,0x0)/NVMe(0x1,15-AD-CD-26-28-B7-26-00)) - Windows on this disk
OpenCore 0.6.1 MacOS 10.15.7 both disks GPT UEFI
Both OSs boot nicely and work as a charm when selecting either of the disks as boot disks in the BIOS.
However, trying to boot Windows 10 from the Opencore Bootmanager (no matter whether PickerMode=internal or OpenCanopy) causes a Windows Blue Screen ("SYSTEM THREAD EXCEPTION NOT HANDLED").
To be on the safe side, I have added an appropriate entry to Misc->Entries:
<key>Arguments</key> <string></string> <key>Auxiliary</key> <false/> <key>Comment</key> <string>Not signed for security reasons</string> <key>Enabled</key> <true/> <key>Name</key> <string>Windows 10</string> <key>Path</key> <string>PciRoot(0x0)/Pci(0x1,0x1)/Pci(0x0,0x0)/NVMe(0x1,15-AD-CD-26-28-B7-26-00)/HD(1,GPT,2E9695CB-0F9A-4005-AADB-2FF9C96AD02C,0x800,0x32000)/\EFI\Microsoft\Boot\bootmgfw.efi</string> It points to the Windows 10 bootmanager on the Windows disk's EFI partition.
What's wrong with that? Why does this cause a BSOD? It is not clear to me why it works when booting from BIOS but not here.
config.plist attached (but maybe it has no relevance for the problem).
today I noticed that there is a LED on the F4 Key on the Precision Keyboard ( same as on F1 Key ). Does anyone have a code snippet that shows how to set the LED?
I've found a solution. The Method SB.PCI0.LPC.EC.HKEY.MMTS controls the LED state. It has one parameter:
0x00 - LED is off
0x02 - LED is on
0x03 - LED is blinking
I've build a LED toggle for my Thinkpad T460. Who wants to give it a try could find my source here
I know that a lot of you are using a Lenovo Thinkpad as Hackintosh. For those i've created an Assistant Application that allows you to use all your Function Keys on your Laptop. It should be compatible to all T-, R-, X- and E-Series Models with the right Keyboard mapping.
