Unless you have a DSDT that was repatched off BIOS A22, expect to experience garbled graphics on screen. To avoid this, maximum BIOS version is A12. To revert to that BIOS version, 1st downgrade to tjhe lowest possible version available on Dell's web site, then upgrade to A12.


You'll find full installation details in this guide:


The HD4000 Capri layout to use depends on your built-in LCD resolution. Inject layout-id 0x01660004 for resolution GTE 1600x900, otherwise use 0x01660003 for lower resolutions such as 1366x768.


All your USB ports will workj as long as you:

1) rename EHCx devices to EH0x

2) inject/install a USB injector kext (Rehabman's USBInjectAll highly recommended)

3) use the appropriate SMBIOS (MBP9,x)
