You might have to move an existing MPX module from slots 1-2 to slots 3-4 in your Mac Pro.

You can also find installation instructions in the quick start guide in the Pegasus R4i package and on the Promise website.

Promise Utility Software Series Of Tones

When Mac Pro first recognizes the module, youll hear a series of tones from the module itself.

And youll hear another set of tones when you log in and the volume mounts successfully.

To manage the Pegasus R4i, install the Pegasus Utility software.

Promise Utility Software Update Clone 1

ONLY ONCE EVERYTHING IS CONFIRMED WORKING for 7 days, then update Clone 1 as your MASTER.

Cycle clones between 2 and 3 on whatever interval you choose.

The system drive on workstations rarely changes that much in a crucial manner and for many a bi-weekly update between multiple sources if sufficient.

After effects stopped displaying anything again and Premiere wont launch with this video driver issue.

I restarted, now its displaying stuff again, but in my comp, the video footage is displayed like this: View attachment 893477.

Just on a whim, restart your Mac while pressing the D key on your keyboard.

If its JUST your video window (not the entire screen) that shows issues, it very well could be corrupted file system andor permission issues (even at the root level) that are not allowing applications to properly access the system.

If youve moved your GPUs andor swapped PCIe cards, reseat EVERYTHING.

If there are the same video artifact issues, that is a METAL issue and very likely related to the MP7,1 not being supported by ANY Adobe app as of right now.

Your GPU is not on the approved list and Catalina just sucks with GPU performance (and issues) across software vendors.
