AMI PCI-E AHCI & NVME UEFI Module Names?

[oXYnary]

I haven't seen much on this from my search here, the closest thread I could come to was this offsite.

While I don't need NVMe at this time, I do need ACHI via PCI-E to boot an SSD.

I'm attempting this on a Supermico X9SCI-LN4F
Bios: http://www.supermicro.com/support/resour...px?ID=3127

Anyhow, I tried
x10DRWN
Bios http://www.supermicro.com/support/resour...px?ID=3410
X9DAi
Bios: http://www.supermicro.com/support/resour...px?ID=3325


Both according to documentation support at least NVMe.  However, from my original link above, there is no Nvme, NvmeSmm, NvmeInt13 files in either.  There are no differences in at least the names of the AHCI modules: AHCI & AHCISMM.  Is there some list of what modules in the AMI bios effect booting from PCI-E via AHCI?  Would the NVMe module have that included?

The chipset on the board is the C204 PCH.  Should I search for another manufacturer entirely for one that supports AHCI?  Is this a straightforward mod, or is it going to require hex editors?  Last time I tried hexing, I ended up making two bios roms unbootable until reflashed.

i'm see you board bios inside and i'm not find any hidden nvme option, my think this feature com's with next gen4 1150 series

I found this page. Seems nvme isnt needed so much as a special samsung ahci module for uefi.

Issue is I tried 3 different samsung_m2_dxe and reflashed bios. Still, bios wouldnt boot from drive. Not even in legacy.
