Need some input on ASRock X99 WS - trying to boot to Sierra installer

08 June 2017 - 12:44 PM

Hi all,


I'm trying to get my ASRock X99 WS board with an E5-2695v3 to boot the Sierra installer (made using 10.12.5 but have tried earlier versions of the app too). I'm not having much luck, so would appreciate some help. I get almost all the way through the boot process but get a reboot at IOConsoleUsers: gIOScreenLockState.




CPU: Intel Xeon E5-2695v3
Mobo: ASRock X99 WS (not the WS-E) spec here
GPU: Quadro 295 but have also tried an even older GT 9500


This build was my old server hence the spec. The eventual aim is to drop in a better GPU to facilitate 4K displays and use it as a workstation for LR and PS and some 4K vid editing, but I need to know if I can get it working first.


What I've tried:


Varying boot arguments including disabling NV, web drivers etc

Varying settings in UEFI such as disabling C States, Serial Ports, Virtualisation etc.

Different system definitions (Mac Pro 6,1 and 5,1)


There have been plenty of success stories with the ASRock X99 Extreme 3's and 4's which I think only have a few small differences such as Intel Graphics and (I think) some have realtek Ethernet. The WS has no integrated graphics as they are assuming you're gonna drop a dedicated beast in for your applications. As such, I cannot fall back on Intel graphics. If the problem is one of the GPUs, I can get another, but I don't wanna grab one and then find it's the board.


I have attached my Clover folder, I'm not very experienced with Clover [I'm a legacy guy ;)] so I would appreciate any help.


Thanks :)
