My Ubuntu file server MB died :(! I need to replace it with one that supports legacy BIOS mode (CSM) as the ASR-51245 RAID controller I have doesn't work in UEFI mode and the system was build in BIOS mode anyway.

I'm after a budget solution so an m-ATX board with integrated CPU would do, but the case will take a full sized ATX MB, so they are fair game too.

Recommendations sought as I found MB manufacturer web-sites remarkably coy about whether they have CSM support or not.

If anyone in UK has a slightly used setup that would fit the bill, I could also be interested in that option ...

Many thanks
