big mystery :


What do   3 long POST ERROR beep sounds signify

It is a good idea to actually connect a beeper-speaker and both POWER LED as well as HDD LED and a USB cable with a LED in it.

That way you see and hear much better during power cycles or UEFI freeze / USB mouse freeze what is going on.

In particular, BIOS BEEP codes will be sounded upon BOOT ERROR, which does occur in some cases. The mainboard then reboots during circa 60 seconds but does not freeze.

Without hearing POST beeps, you might mistakenly think that the machine is frozen. Especially if there is mouse trouble of some kind, which the version 4.6 UEFI of May 2021 essentially fixed for me.]]> Sat, 19 Jun 2021 13:53:36 +0000 https://forum.asrock.com/forum_posts.asp?TID=19087&PID=87790&title=b450mhdv-r4-0-with-picasso-apu#87790 https://forum.asrock.com/forum_posts.asp?TID=19087&PID=87789&title=b450mhdv-r4-0-with-picasso-apu#87789 Author: zzu

It is a little confusing seeing Audio settings scattered across multiple UEFI menus.

Make just one SUBMENU named "Audio" with everything audio in it !

Since printed manuals stopped describing all those UEFI abbreviations and what not.]]> Sat, 19 Jun 2021 13:21:11 +0000 https://forum.asrock.com/forum_posts.asp?TID=19087&PID=87789&title=b450mhdv-r4-0-with-picasso-apu#87789 https://forum.asrock.com/forum_posts.asp?TID=19087&PID=87741&title=b450mhdv-r4-0-with-picasso-apu#87741 Author: zzu

seems like this motherboard UEFI does expose bifurcation.

like 8x or 4x4 PCI lanes for sharing or whatever.
