    Upgraded to Windows 8.1, now SecureBoot has excluded access to the BIOS


      I've got a pc with an Intel mother board DH87RL, AA number AAG74240-401, BIOS Version Intel Corp. RLH8710H.86A.0320.2013.0606.1802, and an Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz processor. Using the Intel® System Identification Utility, I got the report reference ID 0225 3409 I upgraded my machine to Windows 8.1 and after that I was told that SecureBoot wasn't configured correctly. So I restarted, waited for the Intel logo, hit F2, and changed my SecureBoot settings.  I changed it from off to on, I believe.  I saved and restarted.  Now, everytime I restart first I hear 4 loud beeping sounds and I do not see the Intel logo, the first thing I see is the Windows desktop.  It's as if the Intel splash screen is not displaying correctly.  When I hit F2 repeatedly on boot I'm guessing it goes to the BIOS, because in this case it does not boot to Windows, but it also does not show me the BIOS screen. So, in summary, after I turned on SecureBoot in the BIOS, I can not see the Intel splash screen on boot, nor can I see the BIOS screen if I hit F2. Changing the jumpers on the mother board (as was suggested earlier in a similar discussion) didn't help. The BIOS is still not accessable ever since I've activated Secure Boot,  after installing MS Windows 8.1. Any suggestions?
