Oh -- you meant linux-based sw-raid. SW-raids are included in
many Dell BIOS's, no-hardware is involved -- just SW -- and they work fine
to boot off of.

That's what is normally called fakeRAID as the BIOS only sets up the RAID
drives and everything else is done by software. And it *only* works
reliably with Grub when doing RAID1 i.e. mirroring. Grub can't boot
reliably from striping sw-raids as it has no driver for that.

Just for clarity, there are two different RAID implementations to
consider here.

"linux-based sw-raid" would normally be taken to mean RAID implemented
by linux and using the mdadm program and friends, with device names like
/dev/md*.

BIOS-based fakeraid is different.
