hmmmm……itsas35.sys is the driver provided with P14.2. (I’m using the program under win11.)
This is actually the ItSas35_Win10_Win_Server_2016_2019_PCIe_P16 driver downloaded from the official website.
The driver files since the P23 are all mpi2ses.sys, I did use the 9500-16i driver which is itsas35i.sys not itsas35.sys.
Both of these drivers and the P411W-32P_4_1_2_1_HBA_signed_P14.2.fw firmware will cause a BSOD.
It occurs to me that after updating the firmware I’ve been using icydock’s MB699VP-B V3，No try sff-8654 to sff-8639 connector…
Maybe it’s because of the backplane?
