I will not be able to help you.
But maybe give this list try:
Look for PCIe Slot Configuration:
In the BIOS, look under sections like Advanced, Chipset, or Peripherals. There might be an option to configure PCIe slots or ports individually. Look specifically for settings that mention "PCIe Bifurcation" or "PCIe lane allocation," as these control how PCIe lanes are distributed. You’ll want to change this from x1 to x4 if it’s currently splitting the lanes.
Check the SFF-8643 Port Settings:
Since this is a more specialized motherboard, there may be a specific setting for the SFF-8643 ports. Look under the storage or peripheral device settings. It might be listed under something like "SATA Express" or "NVMe Configuration."
BIOS Update:
If you’re stuck on an older version of the BIOS, the settings you need might be locked or unavailable. While you’ve already checked the support page for the 8-SATA version and found it incompatible, it might be worth reaching out in community forums or groups for this motherboard (if any exist) to see if someone has a newer BIOS version available for the SFF-8643 version.
Alternatively, consider looking for updates on unofficial BIOS modding sites, but exercise caution as these could void any warranties or cause other issues.
Modding the BIOS (if you’re feeling adventurous):
If no official BIOS is available, some users go the route of BIOS modding to unlock hidden features like bifurcation. Tools like AMIBCP (American Megatrends BIOS Configuration Program) allow users to tweak certain settings, but this comes with a risk, and I would only recommend this if you have a backup plan.
Fallback Option:
If you're unable to find a solution via BIOS, you could consider using an external PCIe card that supports NVMe or SATA over the SFF-8643 connectors to bypass the motherboard's settings. It’s not ideal, but it’s an alternative.
Consider Platform Limitations:
Finally, double-check if the CPU and chipset combination you’re using even supports the level of bifurcation you need. Some motherboard configurations may not be fully unlocked to adjust PCIe lane allocation dynamically depending on the chipset or CPU installed.
