Many thanks to @RolloZ170 for help with the EPS cable.
Next challenge will be the boot drive. I have a Samsung PM991 Nvme 2242 drive, which at first test doesn't show up in boot options, which was kinda expected. I know the issue is the UEFI bios doesn't have the code to see nvme boot drives.
There are BIOS Mods , or boot from USB (no thanks), or just get a SATA drive.
This is bios version 3202. Any recommendations for best option?
edit: oh the Bios is old, but 3107 has "1. Support ASUS NVMe devices display in post screen." in list of changes.. hmm
blah blah found out the mobo supports booting from nvme just fine. Thanks to the helpful folks on win-raid.com
UPDATE: I've not been able to see the PM991 Nvme drive at all yet, no matter the CSM, AHCI settings, and also nothing in Debian 11 Live.
This leads me to believe the 1x pcie lane from the 2242 slot is routed to the 2nd CPU. While that might seem trivial, it means that if i install the OS onto that drive, i won't later be able to remove the 2nd CPU in case i don't need the capacity and want to save on power and heat etc, not without reinstalling everything onto a SATA drive.
That little issue is really bugging me atm, i'm thinking i should just order a 2242 SATA drive and be done with it, but even the prices of those has nearly doubled recently according to a quick market scan, for a 128GB the older ones with less IOPS are 30€, newer faster ones almost 60€! Doesn't seem like much, but when you need like 3 thousand other components and cables, it all adds up.
I haven't installed the 2nd CPU yet to confirm, because it might make the system unbootable without the EPS cable, and i wanna use the system to upgrade firmware on myLSI3008 LSI SAS9300-8i controller, and also check out the stats and fw of the used DC P3700's i got from an ebay seller while i wait for the cable..
