Asrock X79 Extreme 11 No post beep during test boots error A2


Oct 5, 2012
Hello, on several test boots I get no post beep the debugger on the mother board says a2 (IDE Detect) not sure what IDE its talking about there's no IDE that exists on this pc everything is sata no IDE to even plug into on the board. Now this is my first build so its probably my fault somewhere I'm just not sure where I've spent 3 days on this built reading the manuals of every item I got over and over again until my eyes burned just to make sure it was perfect I've checked and rechecked the cables and where there plugged into and how there plugged in + - Dummy GND and such not getting much help outta asrock support and cant find much info on the web except the same unanswered question One guy posted like five months ago sounded like I wrote it was the exact Identical situation down to the letter. Since I've never actually plugged a monitor into it I haven't seen bios but wouldn't expect to everyone else with this problem sees blank screens it seems least from what i've read. And actually can't plug a monitor in to check haven't gotten the rest of my stuff for my water system yet still being shipped so I cant leave it on much longer then to just hope to hear that magic beep. And sorry for the long post I'm a notorious ranter. This is what I have built and plugged in so far sorry its a cut in past I'm to exhausted to think straight atm.

You want to go into the bios and make sure that the sata mode is set to AHCI and not IDE. In an Asus board's bios it's under the Advanced tab and it's called the sata configuration. You have three choices , IDE, AHCI and RAID. Because you have a SSD you want to set the sata mode to AHCI.
