    Lenovo ThinkPad T420 with UEFI Only

    Hi all, First of all thanks for @tluck's EFI package and everyone else on this thread ----I got a T420 4180RW2, which has i7-2620M, HD3000 with a device id 0x0126 & NVS4200m with the device id 0x1057 (I turned of Optimus and use the internal graphics chip), QM67 and 1600x900 resolution. I used @tluck's Clover package ( b1942 ) to install 10.8.3 onto my T420. The system has recognized my HD3000 chip with its correct device ID and the resolution works fine, the kexts seemed loaded, but I got no qe/ci what-so-ever. I could not find the reason and would appreciate any help. btw, the nvs4200m's situation is similar: kext loaded and device id recognized, but no qe/ci. Option tested ---- SMBIOS-MBP8,3 & 8,1 graphicEnabler=yes or no load video bios = yes or no dsdt ---- my own without patch and tluck's version, placed in OEM folder. kextstat | grep Graphics: 62 13 0xffffff7f80b3f000 0x37000 0x37000 com.apple.iokit.IOGraphicsFamily (2.3.7) <10 7 5 4 3> 63 0 0xffffff7f80b76000 0x2e000 0x2e000 com.apple.driver.AppleIntelSNBGraphicsFB (8.1.0) <62 10 9 7 6 5 4 3 1> 72 2 0xffffff7f80a66000 0x3000 0x3000 com.apple.driver.AppleGraphicsControl (3.3.0) <71 62 10 9 7 5 4 3 1> 88 0 0xffffff7f80eac000 0x62000 0x62000 com.apple.driver.AppleIntelHD3000Graphics (8.1.0) <71 62 10 7 5 4 3 1>
