So i had this Accelsior collecting dust for some time while the Windows install in my 5,1 is at one of the slow SATA-ports. Idea was to speed it up a little, at least to the SSDs potential, by using this PCIe-card.

It's a Win 10 legacy install from DVD, updated to Win 11 Enterprise. It sits on it's own SAMSUNG 860 EVO 1TB. Boots fine at any of the normal SATA-ports, trays as well as in the optical departement. But with the Accelsior it just does not. Not even if it is the only bootable device in the machine.

I even activated AHCI-mode, following this guide. AHCI show up well activated in device manager. But no luck with booting with the Accelsior so far!

Any ideas anybody?
 
Just tested another 860 on the Accelsior. 2TB in this case, with Monterey / OC on it. And it booted up like a charm.
