GatorGeek Posted July 5, 2017 Share Posted July 5, 2017 Hello I've recently been given an older Dell XPS L321X laptop and am attempting to install El Capitan on it. Dell XPS L321X, i7-2637m, 4GB RAM, BIOS A04, Intel 3000 GPU @ 1366x768, Samsung SSD PM830 @256GB I've created the legacy bootable USB with Clover r4061 and the El Capitan installer following Rehabman's guide. I am able to get Clover itself to boot fine; however, when the installer begins I get a kernel panic and crash as shown in the attached screenshot. I've attached my EFI folder and config.plist in hopes that someone can help me identify the reason for the crash and get me moving ahead. EFI.zipcopy_plist.txt Thanks in advance for your help.

Administrators Bronxteck Posted July 5, 2017 Administrators Share Posted July 5, 2017 you can try removing GenericUSBXHCI.kext from your clover other folder Link to comment Share on other sites More sharing options...
GatorGeek Posted July 5, 2017 Author Share Posted July 5, 2017 I tried it without that as my first attempt at troubleshooting, but it didn't seem to help. Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted July 6, 2017 Moderators Share Posted July 6, 2017 This model has Fresco Logic USB 3.0 and there's no support for it. So the last working OS X that will run on it is Yosemite since GenericUSBXHCI stops supporting Fresco after Yosemite. Update: El Capitan /Sierra installation works. Drive must be MBR formatted Use left USB port to install See here for bootpack 1 Link to comment Share on other sites More sharing options...
GatorGeek Posted July 6, 2017 Author Share Posted July 6, 2017 Thanks Jake. That's certainly helpful information. Is there any hope of GenericUSBXHCI ever supporting Fresco again? Is there any way to disable USB3 on this notebook and live with only USB2 and install a more modern version of OSX? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted July 6, 2017 Moderators Share Posted July 6, 2017 So far I don't see any development of this kext or any other that will support Fresco. Only way to disable the USB 3.0 is to mod the BIOS. You could check https://www.bios-mods.com but I won't be responsible if it bricks your system in the process.

GatorGeek Posted July 6, 2017 Author Share Posted July 6, 2017 Fair enough. I'll see if I can get Yosemite to load on here. Modifying the BIOS sounds a bit beyond my area of expertise right now. Appreciate your time and help here. Link to comment Share on other sites More sharing options...
GatorGeek Posted July 10, 2017 Author Share Posted July 10, 2017 I've been able to successfully install Yosemite now, but am struggling to get Clover 4061 installed on the HDD so that I can boot without the USB. This model does not support UEFI, so I'm forced to install in Legacy mode. But no matter what combination of options I try, nothing seems to work. The install appears to complete, but when I reboot without the USB, all I get is "Operation System Not Found" Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted July 10, 2017 Moderators Share Posted July 10, 2017 I retract my statement in post #5. I got curious and decided to give El Capitan and Sierra a try. I was able to install El Capitan and Sierra but not without issues. Main thing, you need to format the drive to MBR! So that means you'll have to patch the installer with the MBR patch otherwise you won't be able to select the drive during install. You'll encounter the error you're getting now "Operation System Not Found" It's not able to read the GPT formatted drive. Issues I'm encountering: No USB 3.0 Support...right side USB is dead, only usable port is the left side (USB 2.0) Brightness slider not working, brightness stays the same (WIP) After wake from sleep, screen flickers if you don't see the brightness bar to either the lowest or the highest, nothing in between I think the reason is because of the low VRAM 386MB size. My system comes with i5-2467M and only 4GB of built-in ram. You can't add more as it's soldered in. I'd tried patching the FB to increase VRAM to 512 and 1024, but to no effect. Some artifacts will occur due to this low VRAM. I'll write up the steps and bootpack if you're interested in trying El Capitan. 1 Link to comment Share on other sites More sharing options...
