I'm trying to get an optane 905p working on my z390 dark with XP SP3. It sees it as a PCI device on bus 7 and it is recognized in the bios. However, it is not recognized as a drive in the OS. I used the storport.sys with SMART support, and the StorAhci_V1.0_20200928.rar. Should I need to do anything other than replace storport.sys?
I think I found the two files I missed in the previous archive. Playing with it more now.
I'm now using the storport.sys, stornvme.sys, and stornvme.inf from the 905p suggestions archive. I see in event manager that \Device\RaidPort3 and \Device\RaidPort4 and \Device\RaidPort5 encountered an error with stornvme.sys. It then seems to try to make a crash dump and fails.
Disabled Raid in the bios. The message says the error is on "\Device\RaidPort3". Attempting to update the driver for the NVME express controller just iterates the RaidPort (then, RaidPort4...5...etc)
