Yea but why would it hang on B6 and what does 'passcode testing' mean? I suspect it was actually hanging on the disk for some reason but i have no clue that was a few years ago and it seems to work now. I'll probably replace this motherboard in the next 18 months just haven't decided if i will go with amd or intel next round.]]> Tue, 05 May 2020 05:04:03 +0000 https://forum.asrock.com/forum_posts.asp?TID=8893&PID=75083&title=boot-codes-for-extreme4-z68-not-dr-debug#75083 <![CDATA[Boot codes for Extreme4 z68 (not dr. debug) : For further details check the...]]> https://forum.asrock.com/forum_posts.asp?TID=8893&PID=75079&title=boot-codes-for-extreme4-z68-not-dr-debug#75079 Author: komsomolec

I revealed this [URL=https://www.asrock.com/support/faq.asp?id=334]ASRock document[/URL] related BIOS codes.

B6 should be "passcode testing" code.]]> Tue, 05 May 2020 02:11:39 +0000 https://forum.asrock.com/forum_posts.asp?TID=8893&PID=75077&title=boot-codes-for-extreme4-z68-not-dr-debug#75077 <![CDATA[Boot codes for Extreme4 z68 (not dr. debug) : It is not resolve in the sense...]]> https://forum.asrock.com/forum_posts.asp?TID=8893&PID=74967&title=boot-codes-for-extreme4-z68-not-dr-debug#74967 Author: jake21

It is resolved in the sense that the system now boots fine and i have not had an issue with it since a week or two after this post (i forget how i resolved the issue as it has been a bit of time - and yes i"m still running the system 24/7 so it has proven quite durable. One of these days I will upgrade to something new but so far i've not had an immediate need.]]> Fri, 01 May 2020 22:12:37 +0000 https://forum.asrock.com/forum_posts.asp?TID=8893&PID=74967&title=boot-codes-for-extreme4-z68-not-dr-debug#74967 <![CDATA[Boot codes for Extreme4 z68 (not dr. debug) : jake21 wrote:I have an old...]]> https://forum.asrock.com/forum_posts.asp?TID=8893&PID=74964&title=boot-codes-for-extreme4-z68-not-dr-debug#74964 Author: komsomolec

Ok. Thanks. Yea it is getting a bit old. A2 seems to be initializing the disk sub system but i couldn't find B6. Hum. If ice-lake comes out by Nov maybe I'll 'upgrade'. System doesn't seem that old but certainly isn't new.]]> Tue, 12 Jun 2018 16:05:47 +0000 https://forum.asrock.com/forum_posts.asp?TID=8893&PID=52486&title=boot-codes-for-extreme4-z68-not-dr-debug#52486 <![CDATA[Boot codes for Extreme4 z68 (not dr. debug) : BIOS boot screen codes today are...]]> https://forum.asrock.com/forum_posts.asp?TID=8893&PID=52469&title=boot-codes-for-extreme4-z68-not-dr-debug#52469 Author: badbri

BIOS boot screen codes today are often difficult to track down. Asrock uses AMI BIOS which some boot codes can be found here, but they are a bit old: http://www.bioscentral.com/postcodes/amibios.htm
I am thinking you may have bumped something while you "fixed some sata cables", could be ram or some other connection. Have you tried pulling the ram and reseating it ? Note: That board was built around 2011/2012 and would be very susceptible to damage unless you took specific cautions when working on it. Make sure you pull the power cord before checking anything (same goes for new boards too!)
