marv Posted October 21, 2019 Share Posted October 21, 2019 I followed the Catalina section of the guide to prepare a boot medium for my Dell Latitude 7490 (i7-8650U). I also configured the BIOS as per recommendation. Unfortunately I cannot successfully boot into the installer. After some time I get scrambled characters and the stop sign. Any hints of what I can do? Here are screenshots of what I got: And the output of lspci on Linux: 00:00.0 Host bridge: Intel Corporation Xeon E3-1200 v6/7th Gen Core Processor Host Bridge/DRAM Registers (rev 08) 00:02.0 VGA compatible controller: Intel Corporation UHD Graphics 620 (rev 07) 00:04.0 Signal processing controller: Intel Corporation Skylake Processor Thermal Subsystem (rev 08) 00:14.0 USB controller: Intel Corporation Sunrise Point-LP USB 3.0 xHCI Controller (rev 21) 00:14.2 Signal processing controller: Intel Corporation Sunrise Point-LP Thermal subsystem (rev 21) 00:15.0 Signal processing controller: Intel Corporation Sunrise Point-LP Serial IO I2C Controller #0 (rev 21) 00:15.1 Signal processing controller: Intel Corporation Sunrise Point-LP Serial IO I2C Controller #1 (rev 21) 00:15.2 Signal processing controller: Intel Corporation Sunrise Point-LP Serial IO I2C Controller #2 (rev 21) 00:15.3 Signal processing controller: Intel Corporation Sunrise Point-LP Serial IO I2C Controller #3 (rev 21) 00:16.0 Communication controller: Intel Corporation Sunrise Point-LP CSME HECI #1 (rev 21) 00:17.0 SATA controller: Intel Corporation Sunrise Point-LP SATA Controller [AHCI mode] (rev 21) 00:1c.0 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port (rev f1) 00:1c.2 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port (rev f1) 00:1c.4 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port #5 (rev f1) 00:1f.0 ISA bridge: Intel Corporation Sunrise Point LPC Controller/eSPI Controller (rev 21) 00:1f.2 Memory controller: Intel Corporation Sunrise Point-LP PMC (rev 21) 00:1f.3 Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21) 00:1f.4 SMBus: Intel Corporation Sunrise Point-LP SMBus (rev 21) 00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (4) I219-LM (rev 21) 01:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.

Administrators Hervé Posted October 21, 2019 Administrators Share Posted October 21, 2019 Try without the patched DSDT; either remove it from ACPI/patched folder or select BIOS.aml table from Clover main menu->Options->ACPI configs when Clover boots.

marv Posted October 21, 2019 Author Share Posted October 21, 2019 Thanks, deleting ACPI/patches/DSDT.aml helped. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 21, 2019 Moderators Share Posted October 21, 2019 @Hervé You should be able to eliminate the DSDT.aml and add the following to enable the Fn+11 and Fn+12 for Brightness: SSDT-XOSI.aml & SSDT-BRT6.aml (attached ) and the following 3 rename patches: OSID -> XSID _OSI ->XOSI BRT6,2 -> BRTX,2 (in those order) FnKeyforBrightness.zip Link to comment Share on other sites More sharing options...
muttonhead411 Posted November 2, 2019 Share Posted November 2, 2019 Hi, I'm also facing the same issue as above, but deleting DSDT.aml did not help. I'm stuck at boot with this on screen, before it freezes. Any guidance on what else to try? Its odd cause my Mojave installer boots up fine Link to comment Share on other sites More sharing options...

muttonhead411 Posted November 2, 2019 Share Posted November 2, 2019 I basically used your catalina boot pack as it is without changing anything. How can I check to confirm @Hervé? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted November 2, 2019 Administrators Share Posted November 2, 2019 Details are available in the thread Requirements for Catalina which happens to be pinned to Our Picks column available on forum home page. I probably left the DW1820A properties injection in the Clover config. If you don't have such a card, that may cause issues... I guess I need to remove or comment out this injection in the pack again. Link to comment Share on other sites More sharing options...
muttonhead411 Posted November 2, 2019 Share Posted November 2, 2019 @Hervé apologies but which thread are you referring to on our home page? I have checked both the pinned post, don’t see anything related to this. Also I’m still on DW1820A, so its probably not that issue. Odd though, because I am able to boot clover and launch my Mojave’s installation fine, its just not able to boot Catalina installer. Freezes at some point with the no entry sign...

muttonhead411 Posted November 2, 2019 Share Posted November 2, 2019 Whops I found the thread. I’ll check again. Maybe I’ll post by clover folder next. Seems like a Catalina specific issue. Link to comment Share on other sites More sharing options...
