Driver issue

Question

I installed a board in my XPS Special Edition Tower; it emulates a SCSI drive and will allow me to move files off an old audio recording system and onto my PC for editing.  I keep getting a driver error despite the driver having a legitimate signature.  The guy who owns the company, Bill, that makes the board & software has been trying to help me disable the feature that checks for valid signatures on drivers but we get an error when attempting (spelling might not be quite right as he was trying it remotely and I was just watching the screen) to run 'BDSedit /set testsigning on' from the command prompt.  The error is something to the effect that changing this parameter is not allowed.  Bill told me that we need to get into the BIOS to toggle that feature.  However, when I reboot and attempt to enter the mode, that in the old days would allow you access to the BIOS (via repeatedly tapping F2 or F10 or F12 or ESC; we tried them all), I just get the windows sign in screen after a very long boot process.  Bill thinks it's because I am using the HDMI port to connect to a flat screen TV that I use as a monitor.  He thinks that I'm not seeing the screens that would otherwise be seen because the driver for the HDMI isn't loading in time for me to see that screen and that the long boot is due to the timing out of the window where you'd have that option (if you could see it).  Kind of hard to articulate this clearly but, anyone have any ideas how to fix my problem?

If you have Windows 10 'fast startup' enabled (Windows sets this as default) then in most cases you can't access the BIOS at bootup (F2 for a Dell).   Disable fast startup and see if that lets you access the BIOS (Dell calls it setup).  However not all options in BIOS' are always available in the Dell BIOS so that still may not solve your problem.  The SCSI developer has to fix the problem, not the PC or Windows compensate for his shortcomings.   https://www.windowscentral.com/how-disable-windows-10-fast-startup#:~:text=How%20to%20enable%20and%20disable%20fast%20startup%20on,checkmark%20disappears.%208%20Click%20Save%20changes%20.%20

What video card do you have and is there a firmware update listed for that exact card under Video on the support page for XPS 8930. It fixes an HDMI issue, which may -or not- be related to the problem you're having. So you may want to run that update, if offered for your card.

The option you may need to disable in BIOS setup is Secure Boot. You may have to remove that new card, reboot and open BIOS setup by tapping F2 when you see the Dell splash screen. Then disable Secure Boot, save the change and exit setup. When you get back to the desktop, power off normally in Windows, reinstall that card and see if it works now....

'The guy who owns the company, Bill, that makes the board & software has been trying to help me disable the feature that checks for valid signatures on drivers'  Driver signtature enforcement is mandatory when secure boot is on. ELAM will not allow hardware or drivers to load without microsoft WHQL certificate. https://docs.microsoft.com/en-us/windows-hardware/drivers/install/early-launch-antimalware
