It's an old motherboard but my point is that it boots fine when either: one NVMe and the network card, or both NVMe are installed, but not when all three are installed. How would that be related to FreeBSD compatibility? The chipset and all devices that I am trying to install are supported by FreeBSD 11.x. I just tried booting into a Debian live system and it also didn't enumerate NVMe drives properly. This means that it's not FreeBSD related and is no longer relevant for this list. I will try to play with BIOS settings to see if I can make it work that way. Thanks for all the help. Nvme drives are weird about power. I distrust the power estimate of 5-9w earlier in the thread... given the oddity with debian, it's not too crazy to think that. How far does FreeBSD boot though?
