I have a Z270 Classified on 1.02 and during boot it pauses on A2, sometimes A0, for about 30 seconds or more. This is the "IDE Detect" phase.
 
Drive setup is 2x Samsung Pro 960 NVMe cards, a Samsung Pro 850 in the first Intel Sata port, two Evo 840's in two Marvel ports and two older BD-RW's in the other two Marvel SATA ports. They all work just fine.
 
Same thing occurs with hotplug enabled or disabled.
 
Before I start pulling random things out to see if anything makes it better, would anyone happen to have thoughts on what might cause the pause? :)

    When that happened to me it was only in the BIOS SWITCH  1 (top) position
    BUT that was with BIOS 1.01
     
    After loading the new BIOS and possible a different driver loading all switched positions booted the same with out the long 30 sec pause.
     
    In my build notes I see that when I was having that problem a BIOS picture I took of PHC configuration ( advanced tab)
    For my Intel PCH  the ME FW version listed 0.0.0  but after new BIOS and other fiddling it said 11.6.0.1126

    I have just gotten a X99 FTW this is a new build, except for the SSD drive. It would cycle then hang on A2 then go to d7. I then hooked up the keyboard and the d7 stopped or was cleared but would hang on A2 and would not boot. Can anybody give me an assesment on this? Thanks!

    A2 = motherboard is looking for boot device.
     
    Possible issues:
     
    #1 Dead ssd/hdd.
    #2 Faulty sata cable.
    #3 Bad cmos battery.

    Mine only pauses on A2; it does boot, just takes a while. If yours doesn't boot at all, after waiting 30 secondsish, then it's a different issue to the OP.
     
    Experience says the cable is the primary suspect for your problem, then the drive or the port you plugged it into.

    Just use a non SSD sata drive and copy over later that is what I tried as I wanted a M.2 SSD later and the Intel ones were back ordered.
     
    #3 Bad cmos battery.
    AIDA64 is one test program that will give a  CMOS battery voltage level
     
    In the old days if the power supply is on the MB will not take power from the battery and will run the CMOS and RTC.
    so to test you had to pull the plug from the power supply and see if you lost the time or use a volt meter and look for 3.3 Volt in circuit
    on the battery holder.
    If you run on a UPS you may never know that you have a low CMOS battery
     
    if you pop the battery out it will light a regular LED ( try the legs on the LED both ways ) 
     
    -------------
    I think they moved the RTC circuits into the south bridge not sure and I have no idea now were the CMOS is located and if there is only one CMOS chip for all 3 BIOS chips.

    Thanks Cordorb! This is a new build. My old build got fried when an electrical storm it a transformer. And sent a power surge before all power was shut off. It literaly damaged my CPU and the socket some of my fans would not turn back on. everything has been replaced with new parts except the ssd drives and hdd drive. !'m now running a EVGA PSU  EVGA X99 FTW-K MB i76850K CPU Corsair Dominater platnum RAM and EVGA 1080FTW GPU so the only thing that was not new was the drives and it looks like I'm going to have to get new drives now. Thanks for sharing your info with me!
