Same problem for me with a Galaxy
tab pro S (128 Mo dedicated ram with it's 8086 191E0300 (HD515) graphics card)
- under El Capitan 10.11.6, it shows 11 Mb ram, and no acceleration.
- under Sierra : I can only boot with safe mode (-x). I tried the no cache option without success (it hangs after 2 60" tries). Without no cache option, it reboots.
Using the latest clover for Sierra (downloaded today
https://sourceforge.net/projects/cloverefiboot/)
- CloverConfigurator ACPi enables Fixdisplay
- CloverConfigurator Devices enables 0x191e0000 (also tried 0x191e0300)
- CloverConfigurator Graphics enables Inject Intel
Boot arguments : dart=0 npci=0x2000
Smbios : using MacBookAir 5.2
No Dsdt.aml
Can I mix Old way fixes and New way fixes in the acpi Tab ? (Clover Wiki explains all functions, except this question)
The laptop bios is basic : no DVMT-prealloc setting, but 128 Mo should be enough for it's 2160x1440 resolution.
More time tomorrow to diagnose this problem !
@RehabMan : I read as many tutos - explanations from you as I can. I'm starting learning how to use dsdt / Iasl ...
