  1. Hi Jake. The EFI posted wasn't actually the one I was using - have a load of different ones on my desktop and uploaded the wrong one. At your suggestion I tried out the install USB from my E6530 which actually booted up OK after I had checked the BIOS settings. On trying the same sequence with the E6540 install usb it also booted up fine and I completed the installation of Catalina. So it looks like I actually have a weird hardware problem on my laptop - boots Clover fine but only after a restart (exiting BIOS settings causes a restart rather than a cold start). Catali
  2. Thanks for that. Added new config.plist but still hangs on boot up. CLOVER_E6540_Catalina_new_config.zip
  3. Hi Jake. Removed SSDT.aml but didn't make any difference - still hangs in the same place. I built it on my E6530 but for i5-4310M processor - so would it be good for my E6540 as it has the i5-4310M or it that a big assumption? found this code in SSDT.aml: custom mode...........: 0 host processor........: Intel(R) Core(TM) i7-3630QM CPU @ 2.40GHz target processor......: i5-4310M number of processors..: 1 baseFrequency.........: 800 frequency.............: 2700 Looks like I'm out of luck with this install. As a final task I think I'll try and
  4. The display is a disaster area for sure but it's temporary. The machine came with a FHD display and I thought it was an added complication to install Catalina with it installed.So I have installed a scrap screen from my spares box for the meantime - but it's not pretty. The installer is vanilla built as outlined in the many excellent guides on the site. OS I think is 10.15.6 and Clover is v5118. Reset BIOS and set as suggested. Even started with F12 to make sure it was doing a UEFI boot. The version is A17 - unable to update to latest (goes through the motions but doesn't actu
  5. Many thanks Jake. Did as suggested and my boot gets a lot further but not all the way. I've attached my bootpack and a pic of where the boot halted. Any ideas of what to try. EFI_e6540_test.zip
  6. Hi Guys Previously installed Catalina on E6530 and works great but now need to install on E6540 for a mate. I started with this thread as it seemed to have all to have an EFI close to my actual laptop but unfortunately unable to get the installer to boot. I have attached my Clover folder. Clover boots for a bit and then hangs - no panic. Could someone have a look at the files or even suggest a better starting point for my build. Cheers. Specification of machine E6540 i5-4310M 6MB 480GB SSD Bios A17 (unable to get it to update to a later version but working o
  7. So decided to add the bios revision to the post only to find the bios was A07. Updated to A21 and both issues actually solved. Next job is to update the screen to Full HD 1080p.
  8. Hi. Been installing Catalina on a Dell Latitude E6530 using the excellent guide but have run into some issues. The install USB stick will display the apple logo and timer line on the laptop LVDS LCD screen until it gets about 2/3 across (looks like when it loads the display drivers) and then LCD screen goes black - although found that if you plug in a HDMI screen it boots to the end using the external screen. I went ahead and installed Catalina which went very smoothly but even when booting from main HDD LCD display will go blank during boot up but boot up completes
  9. Cheers. That did the trick so everything working 100%. Thanks so much for your help.
  10. Thanks for the reply. I have rebuilt it countless time but the result is the same. Here is the output from the rebuild:- sudo ./permission.sh Password: rebuilding //System/Library/PrelinkedKernels/prelinkedkernel kext file:///Library/Extensions/DisableTurboBoostBattery.kext/ is in hash exception list, allowing to load Kext with invalid signatured (-67062) allowed: <OSKext 0x7fba2884aaa0 [0x7fff8e37eaf0]> { URL = "CodecCommander.kext/ -- file:///Library/Extensions/", ID = "org.tw.CodecCommander" } KernelCache ID: 79467EA040F45B7C043B1554575197F2 k
  11. I was hoping someone could help me with an issue on an E5540 regarding loss of audio after sleep. The E5540 is running High Sierra and was installed using this guide and installation went fairly smoothly. I used the E7440_HS.zip bootpack as the E5540 does not have Nvidia (tried to rework for no Nvidia but was not able to get it working). Everything worked except SD card but fixed config and now works fine. However I don't have audio after waking from sleep - works fine (speaker and earphone) when first booted. After sleep no audio on speaker unless you plug/unplug earphones which
  12. More progress today. The DSDT-E6230-HD4000 allows me to boot up in 1080p and the USB ports and SD card reader all work fine. However external HDMI port is still not working. Have tried Enoch options IntelCapriFB=4 and DualLink=1 individually and together with no difference. After a little rooting around I discovered there are patches for AppleIntelFramebuffer.kext here and I applied these, reinstalled kext in SLE and rebuilt the cache. System rebooted fine in 1080p mode but HDMI port still not working. Can you suggest what else I can try. Cheers Aubrey
  13. Ran into some problems editing the DSDT.aml file I was using. MACiasl was not able to decode it and iasl.sh could decode it but found error when trying to recompile. However I discovered this DSDT-E6430-2CH.aml file in this guide which seems to have the patch already applied so opted to use it instead. It seems to work fine and I was able to boot up in 1080p mode - on the down side I don't seem to be able to use the external HMI port any more and the SD card is not working with the DSDT. My best option seems to be to try and sort out the decompile/compile issues with my first DSDT file
  14. Yes I have the dual mode cable and the LCD panel is working fine in the BIOS (in 1080p mode) and with Enoch. I will make the patch as you suggested and see if it gets me all the way to the desktop in 1080p Cheers
  15. Happy to report that HMI and SD card working perfectly but need some help with upgrading to a 1080p lcd screen. After a bit of searching i found the DSDT-E6430-2ch.aml DSDT file and tried it out. After replacing the panel system boots up to the Apple timer but screen goes black around half way across - laptop continues to boot up and if I attach external HDMI there is a garbled display (looks like a section of the LHS of the screen is repeated a few times). How should I proceed? I expected that a DSDT file with dual-channel LVDS enabled would probably work OK with 1080p screen but perh
