#178588 — BIOS Settings for Fake-RAID

[Multipart message — attachments visible in raw view] — view raw

At https://wiki.debian.org/DebianInstaller/SataRaid are these words:

Not to be confused with the Linux kernel's software RAID feature (Multidisk
> Device). This is the preferable and more reliable method to establish
> software RAID arrays.
> See the Debian installation guide for more information.


followed by these instructions:

Use the following method only if you want to have a dual-boot system with
> Debian and the other operating system on the same Serial ATA RAID:
> Set up your fake RAID in the BIOS (see owners manual).



I don't want a dual-boot setup. So I went to look at the Debian
installation guide
<https://www.debian.org/releases/stable/amd64/ch06s03#mdcfg>, which doesn't
tell me to do anything one way or the other with fake RAID in the BIOS. I
would assume that since I don't want to dual-boot, and therefore don't want
fake RAID, but rather only the Linux kernel's software RAID, that I should
turn off RAID in my BIOS (UEFI, actually), but when I did so, my
installation of Jessie wound up being a little different than what the
manual says, and resulted in a non-booting system.

So my question: If I don't want to use the BIOS's Fake RAID, and want to
use only the Linux kernel's software RAID, do I want to turn RAID off in
the BIOS, or leave it on? (I'm expecting to have other issues after solving
this one, but I gotta start with the most basic question before I can move
forward.)

Thanks!

Yes.

Also, always prefer dmraid over some fake RAID.
