Hi, sorry for the delay.

Unfortunately this does not apply to j4105. If i disable "fast boot", i cannot see any new item / "CSM"

With the Z370 Gaming K6 The visibility of the CSM module is controlled by disable or enable fast boot. With fast boot enabled the CSM module is removed from the page. This is on the "Boot" page.]]> Thu, 02 Aug 2018 06:51:30 +0000 https://forum.asrock.com/forum_posts.asp?TID=8080&PID=54327&title=j4105-doesnt-have-legacy-bios-csm-mode#54327 <![CDATA[j4105 doesn't have Legacy BIOS (CSM) mode : Hi,i also have the j4105B version...]]> https://forum.asrock.com/forum_posts.asp?TID=8080&PID=54311&title=j4105-doesnt-have-legacy-bios-csm-mode#54311 Author: nightmw

Hi,

i also have the j4105B version and would like to use a LSI MegRaid 9260-8i Raid Controller in it.

Unfortunately i cannot enable the Legacy Bios mode - there is no setting for this in the bios. Therefore I cannot configure the controller using the controllers "WebBios".

If I Plugin the RaidController into to PCIExpress port I can see the controller under the advanced settings of the UEFI Bios. Trying to enter any configuration menu of that controller in the UEFI bios hangs the uefi bios. The mouse is moving, but the bios itself is not reacting to clicks.A reset via ctrl+alt+shift is possible though.

Any help/idea how I could configure that raid controller?

OMV uses a Debian installer so no reason either Legacy or EFI would present this.

Back when I had fiddled with OMV even then they warned you not to install it onto a pen drive but instead to a small SSD or HDD.

I can see in user manual that this option should be present, but I don't have it...

My config:

j4105 itself
Crucial DDR4 2400 4gb
Seagate IronWolf 4tb
PSU beQuiet 400W
HDMI-connected TV
USB-connected keyboard

Because of this, I cannot install OMV - actually this is my main problem. I tried to use both partition tables: MBR and GPT for my pendrive (SanDisk USB3 16gb). I've tried to decrease partition size up to 4gb. No success. Meanwhile unRAID is booting from it. So I suppose pendrive itself being USB3 16gb is not a problem (I've read somewhere that this may cause problems).
