Hello,
A visitor asked me last week how to install linux as double boot on a windows 10 *raid* hpz230.
the raid is a firmware raid, not a software one, present on the motherboard.
on the spot I was not able to make openSUSE to see the raid 1 two disks presents on the system.
YaST-install sees two disks, but can't configure the free space (locked obviously by the raid software).
However, these computers are SLES/SLED compatible

however, I don't see any suse/linux specific data on the raid config page

any clue?
Moterboard RAID or BIOS RAID is what is endearingly referred to a Fake-RAID. Nothing wrong with it, works fine, but depending on BIOS capabilities, unless the BIOS provides a way to sync a new drive in the case of the failure -- you are limited to the life of the original disks in the RAID set. This setup uses "dmraid", not "mdadm" to interface with the arrays. https://wiki.archlinux.org/title/Install_Arch_Linux_with_Fake_RAID Is still a good How to Setup Fake RAID, though you will have to ensure the dmraid module i present in initcfg via Drakut so the arrays can be activated and assembledd during boot. You will install the boot loader to BOTH /dev/sda and /dev/sdb, for example. -- David C. Rankin, J.D.,P.E.
