I noticed that, after upgrading BIOS to latest version A19, if the E6230 booted to black screen and then went rapidly into sleep, I had no graphics corruption on wake. I therefore extracted A19's raw BIOS tables and re-patched the DSDT.

 

I'm pleased to say that my E6230 can now boot without issue with the latest BIOS version. Copy attached below.

DSDT_A19.aml.zip

 

Patches applied:

  • iGPU device renaming from VID to IGPU + injection of _DSM method for layout-id
  • injection of PNLF device
  • injection of AC device
  • injection of IMEI device
  • renaming of SD card reader device to SDXC + injection of compatibility with Apple's own reader
  • renaming of WLAN mini-PCIe device to ARPT
  • injection of _DSM methods in GLAN + EHCx + XHC devices
  • injection of _DSM_method to HDEF device for codec id
  • injection of power settings to EHCx and XHC devices
  • injection of "Darwin" Os to _INI method to support USB3.0
  • injection of IRQ NoFlags to HPET device
  • revamping of _PWR methods to USB devices (EHC, XHC, USB)

Graphics corruption is in fact due to Capri Framebuffer default memory size set at 256MB. Patching this down to 8MB solves the graphics corruption issue with all BIOS versions post A11. Patch is detailed in my E6230 guide.
