Getting stuck on Big Sur installation on Thinkpad T540p

Recommended Posts

I've downloaded Ollarila Big Sur .raw image and using premade efi for haswell laptop from this forum but still no luck to install MacOS on my device. It's always stuck on either waiting root device which can be solved by changing usb port and endless restart at "appleLMUcontroller::smcReadKey Error : received error 0x84 when reading....." 

My device spesification 

i5-4300M

Intel HD4600

8GB Ram

Realtek ALC292

 

i will provide DSDT.aml and snapshot of PCI-Z of my laptop on attachment.

Please help,

Thank you

yes, i've put my installer drive on usb2 port to solve "waiting for root device" problem, and i dont find sata ahci setting anywhere in my bios

 

with some googling i found that my latest bios update remove sata controller setting and now just use ahci mode for disk drive
