Catalina on z840 rx580 help needed after install Drives missing

Recommended Posts


Just installed Catalina to NVME quad Turbo drive using Clover 5102 on Z840 dual xeon rx580 gpu

NVMe ,SAS, & SATA drives are listed after scanning entries in Clover but no SAS or SATA drives showing as available in Catalina after login only NVMe Quad Turbo and G2 SSD all other devices seems to be working as expected.

any help would be greatly appreciated!

Here is shared link to sendme file created with runme 2 app.

Thanks for your help!

Tried the DSDT.aml file you provided:

results in ACPI errors and kernel panics

Which actually helped me isolate & figure out the problem: bad BIOS advanced setting: changed "UEFI except for video" to "legacy for all option ROMs"

no DSDT.aml file required

I have attached a zipped screen of the error FYI and future reference

Thanks again

Sorry for my late reply

forgot to enable the notify on reply option

I missed the kp capture in realtime and recovery involves removal of the rx580 card and installing nvidia fx3800 to boot from usb

and upon reboot I did not get the OSX has recovered for a crash message with option to send to Apple.

My last saved kp was without the DSDT.aml file you provided.

OSX dump:

I'll try your DSDT.aml file this weekend and reproduce the kp
