Welp. Installing Debian on a Mac Pro 4,1 is failing at the point of not being able to identify the internal drive. Grub can see em, the installer can′t. 🙃

Did I mention this computer has the ridiculous Mac Pro RAID card installed?

Did I make a fatal error in removing the drive containing Mac OS X and putting in a fresh drive?

I tried checking for ways to enable AHCI (and struck out on figuring that out with the options available to me in grub from the installation media), tried enabling fake RAID SATA controller mode from grub.

Okay, so removing the RAID card was a little unnerving (documentation is a little scant), but I was able to get it out and the computer then started failing at booting from the external FireWire drive (this is good news, stay with me). One tip, there‘s a bar in the back to slide toward the front to release the card.
Since I have an encrypted disk, the encryption setup is hard coded to the drive assignment at installation (in this case, sda, but with an internal drive in place, it became sda and, well, it did not have encryption nor a bootable OS). Putting the external drive inside got me to the boot step, but now the upper expansion bay fan was at max (not fun for quite, at home use.
I figured I‘d need to reset the PRAM, but after a quick search to verify, I also added unplugged for 30 seconds, pressed and hold the power button for 10 seconds, and then reset the PRAM.

Next to see if I can expand my boot partition to use more of that 4TB on the drive…

For non-Mac people, a PRAM reset is conducted by holding down the Command (Win or Super key on other keyboards) +Option (Alt for you other OS users) + P + R keys until I heard the startup chime twice (hearing the system power down a bit after the first chime was probably the sign you need, but out of tradition of quicker booting system with quiter startups, I wait to hear that bong once more).
