Ok drives are now free, now the new storemi uses StoreMI Bottom Device Storage Controller instead of AMD Virtualized AHCI controller for Ryzen 400 series (if using the 400 series motherboard).
"The AMD StoreMI 2.x installation adds Storage Controllers seen under the Windows Device Manager. You can expect to see a “StoreMI Bottom Device” and “StoreMI Controller [storport]” for each installed hard disk and SSD storage device. Do not delete or modify these storage controllers. Each will be deleted if StoreMI is uninstalled and after rebooting."
however the installer is not installing the new Controller driver,
if you set the AHCI controller to AMD Virtualized AHCI controller for Ryzen 400 series then if prompts you to first uninstall the old store mi
if you set it to standard SATA AHCI Controller it prompts "storemı is unable to Support this motherboard's SATA Source HDD and SATA cache and SSD attachment. Using an NVMe SSD for the cache is supported"
So guess i need to workout how to install this StoreMI Bottom Device and StoreMI Controller [storport] ?
