First thing, running 2 macOS + Windows with one blade only is a bad idea with a MacPro6,1. To make it work reliably you gonna have to choose two.

Second thing, you don't need OCLP to run Monterey on a late-2013 Mac Pro, is natively supported. OCLP does not even support Mojave (Big Sur to Sonoma).
 
Thanks for your feedback! As written Monterey is the step towards running "the newest OS available". As there's no room for more disks, I upgraded to 1 TB (960 GB).

The Mojave partition is for running 32-bit apps and games.

If you really need Mojave, install it to a TB dock/drive/etc. Works fine here.

Mojave with Monterey in the same disk will led to corruption, different and incompatible APFS versions.
 
That shouldn't happen with separate partions? - but with your experience you reckon it will?! Btw, it's Mojave with "whatever OS is newest" = Sonoma right now via OCLP (via Monterey) and then a Bootcamp partition

Yes, it will corrupt the Monterey container/partition/whatever, Mojave APFS version is incompatible and even if you disable auto mounting it will corrupt in the long run.

Anyway, this is way off-topic for a thread that is for tracking BootROM releases.

The on-topic issue is, why I can't install, when the Boot ROM is up to date. Still have to put an original Apple SSD into it to do anything. Thought that would be fixed by now?

Sorry, but this is not on-topic since you already have the current BootROM release.

Once the BootROM upgrade is already installed to the Mac Pro, Software Updates/macOS install/etc won't touch it again until Apple release a newer BootROM upgrade (which probably won't happen again or Apple would be testing the newer firmware by now with Monterey 12.7.6 betas).

Your issue is OCLP or even something related to the Aura SSD.

That's not because you installed OCLP to the Aura ESP?

Mojave is not compatible with OCLP, OCLP spoofs 2019 Mac Pro to run Ventura and Sonoma, so, since 2019 Mac Pro is not compatible with Mojave, you will not get it to install or work.

Remove OCLP ESP, reset the NVRAM and you can install Mojave. If you need OCLP help, please go to one of the Unsupported Mac threads.
 
It's a trash can (2013) model. And right now I'm just asking why I can't install Mac OS on a OWC Aura 1 TB SSD

Again, this is an issue not related to the thread that tracks late-2013 BootROM upgrades.

If you want help with OWC Aura + late-2013, open a dedicated thread for that and/or call OWC technical support.
