hello, pls contact our after-sales  email. , will send you the  newest bios version. thanks

Thank you for the Bios and Windows Key.

For information. With Crucial Storage Executive you can upgrade crucial SSD Firmware to

Drive Firmware Revision:      P9CR40D

But it's no information whats changed

For Bios Flashing you have to disable Secure Boot in Bios before. If not, you are not able to boot the usb stick.
In my case it was not possible to change the secure boot option. It was only possible to changed that entry after removing the second ssd form slot, then it was possible to change the Secure Boot Option and flashing the new bios.
Very tricky
For Backup the old Bios i changed the Flash.nsh entry to
  1. AfuEfix64_5.14.02.0026.efi  SER7V28-ORI.BIN /O
  2. echo Backup Bios erstellt. Weiter mit Taste zum Flashen
  3. pause
  4. AfuEfix64_5.14.02.0026.efi  Phx11HDF723007_SER7PRO_P5C8V31_20230916141813_IPUenable.BIN /p  /b /n  /k /L
Copy the Code
good luck

Simco
