Troubleshooting continues - NVRAM reset required for every boot

Macpro5.1 OCLP 1.2.1 Sonoma

I have a variety of boot discs for this PC. All of which work except for my most recent installation. I just can't figure it out. I've made a lot of progress but just can't get it to boot consistently. If I do a NVRAM reset, it boots smooth straight to the login screen after doing the normal OCLP boot picker and verbose If I shut the computer down, or reboot, it goes into a boot loop where it's sometimes will boot to a black screen and sometimes to a login screen, but it usually takes at least three or four cycles. If I shut it down and do a reset, it boots every time.

WTF? Any suggestions?
